Though the XSLT and XQuery share the same data model, type system and function library they are created by different working groups within W3C in order to work in large collections the query language was initially created and this language deals with the large collections of XML documents and not only with large collection of the documents it can also work with the documents that are individual documents, there are many differences between these languages.
In the web development circles the XHTML is continually expanding, since there are
The web server should be connected to databases it has to retrieve the data and the web server has to process it and format it into HTML and after that it has to be sent to the client. The users can increase the life of the servers by reducing the load on it by using XML and XSL. The extensible style sheet language is a style sheet format for XML documents which is the counterpart to the cascading style sheet in HTML, when the user sends XML and XSL to the client, the client creates HTML for the user the process of the server also becomes fast
Simon sprott who is the author of this article gives us an insight into xml data binding. His article describes how XML data binding guides in managing Xml documents using a collection of simple objects. An XML schema is used for formulation of the rules to define its shape. Generally, an XML document can be read into an XML library and manipulated through simple get and set methods in programming. Similarly, the converse is true. i. e XML data binding library can be the source. This means that a document can be created and serialized as an
Let's suppose that you have an XML document and you need to process its data in a compiling language, such as C or C++. In such a case, you would have to create a program that would automatically parse the requested documents, basing on their structure.
XSD from CodeSynthesis comes to help the programmer work with XML data structures by automating the process of creation of code by creating the required C++ classes from an XML instance specification file.
By using CodeSynthesis XSD, you can easily create programs that work directly
Forms are a part of our lives. They are used day by day in the ordinary life, but online they have a special place. They are the primary way of collecting information, being used for search engines, polls, surveys, electronic commerce, and even on-line applications. Every type of user-interaction on-line is done through web-forms of some sort. However, this technology is already showing it's age. Being created 5 years before XML, it has limitations, that make developer's and user's lives harder. Among them are:
As forms are older than XML,
The XSLT and XQuery standards were created by different working groups within W3C. The both share the same data model, type system and function library, and both include Xpath 2.0 as a sub language. XQuery was initially created as a query language that would work with large collections of XML documents; it can also work with individual documents. So, its capabilities overlap with XSLT, which was designed to allow input XML documents to be transformed into XML or other formats.
Anyway, there are great differences between these
An imperative application of XML is the exchange of electronic information among numerous data resources on the net. XML data always propagate on the net and applications need to add and cumulative data from different resource. It also clean and alter the data to aid exchange. This presentation is about querying language for XML known as XML-QL. This argument is suitable for performing the above jobs. As XML-QL is declarative and relational comprehensive query language of coding and is quite easy that it can be optimized and time. This
An XML Pipeline specifies a sequence of operations to be performed on a collection of XML input documents. Pipelines take zero or more XML documents as their input and produce zero or more XML documents as their output.A pipeline consists of steps. Like pipelines, steps take zero or more XML documents as their input and produce zero or more XML documents as their output. The inputs to a step come from the web, from the pipeline document, from the inputs to the pipeline itself, or from the outputs of other steps in the pipeline. The outputs from a step

Although XQuery was initially conceived as a query language for large collections of XML documents, it is also capable of transforming individual documents. As such, its capabilities overlap with XSLT, which was designed expressly to allow input XML documents to be transformed into XML or other formats.The XSLT 2.0 and XQuery standards were developed by separate working groups within W3C, working together to ensure a common approach where appropriate. They share the same data model, type system, and function library, and both include XPath 2.0 as a
An important application of XML is the interchange of electronic data (EDI) between multiple data sources on the Web. As XML data proliferates on the Web, applications will need to integrate and aggregate data from multiple source and clean and transform data to facilitate exchange. Data extraction, conversion, transformation, and integration are all well-understood database problems, and their solutions rely on a query language. We present a query language for XML, called XML-QL, which we argue is suitable for performing the above tasks. XML-QL is a
In this article, we will walk through marshalling data to and from XML, using a XML data-binding API. The first question is, why? Why not use SAX or DOM? Personally, when I sit down to work with XML, I get frustrated with the amount of code that you need to write to do simple things.
I came across JDOM and found it to be something I was looking for. DOM is built to be language-agnostic, and hence doesn't feel very "Java-like." JDOM does a great job in being DOM, in a way I would like to use it in Java.
For some applications, I don't want to even

Emerging XML technologies are available in the following categories on alphaWorks:
* Database - XML opens the door to a new generation of databases: object databases that can manage heterogeneous, non-tabular information. Relational databases manage a subset of XML, but XML is more general.
* DTDs - The XML Document Type Definition (DTD) defines the constraints on a specific class of XML documents. It is used by the XML parser to validate and interpret individual XML documents.
* Editors - XML is optimized for creating, editing, and viewing
Unlike the original HTML forms, the creators of XForms have used a Model-View-Controller approach. The "model" consists of one or more XForms models describing form data, constraints upon that data, and submissions. The "view" describes what controls appear in the form, how they are grouped together, and what data they are bound to. CSS can be used to describe a form's appearance.
An XForms document can be as simple as an HTML form (by only specifying the submission element in the model section, and placing the controls in the body), but XForms

ABSTRACT
This paper is devoted to the construction of processors of a language for describing links between resources in XML documents, which is based on the application of functional programming methods and representation of XML data as S-expressions. An implementation in the high-level functional programming language Scheme, the system SXLink compatible with the XLink specification of the W3 consortium, is considered. A survey and comparative analysis of the existing implementations of the XLink language are given. Typical difficulties associated
Introduction
This specification defines the XML Linking Language (XLink), which allows elements to be inserted into XML documents in order to create and describe Link between resources.
XLink provides a framework for creating both basic unidirectional links and more complex linking structures. It allows XML documents to:
*
Assert linking relationships among more than two resources
*
Associate metadata with a link
*
Express links that reside in a location separate from the linked resources
An important application of XLink is in
This section describes the terms and concepts that are essential to understanding XLink, without discussing the syntax used to create XLink constructs. A few additional terms are introduced in later parts of this specification.
2.1 Links and Resources
[Definition: An XLink link is an explicit relationship between resources or portions of resources.] [Definition: It is made explicit by an XLink linking element, which is an XLink-conforming XML element that asserts the existence of a link.] There are six XLink elements; only two of them are considered
XML Linking Language (XLink) is a generic framework for expressing links in XML documents, to complete its placement in hypertext systems such as the Web. It can be used to create simple links, such as those that are an essential part of HTML documents, or more complex types of links, such as multiended links and link databases.
XML Linking Language (XLink) Version 1.0 [W3C Recommendation] provides a generic framework for expressing links in XML documents. Hypertext, which requires linking, is the foundation of the Web, and adding sophisticated
Description
XLink defines how to insert links in XML documents. It specifies a framework making it possible for XML applications to recognize XML elements as having link semantics. In addition to the simple, two-ended, unidirectional links which are well-known from HTML, XLink allows more general links, which must not be embedded in the document, can have any number of ends, and can be multidirectional.
XLink is the XML Linking Language. It allows elements to be inserted into XML documents in order to create and describe links between

In order to appreciate XML, it is important to understand why it was created. XML was created so that richly structured documents could be used over the web. The only viable alternatives, HTML and SGML, are not practical for this purpose.
HTML, as we've already discussed, comes bound with a set of semantics and does not provide arbitrary structure.
SGML provides arbitrary structure, but is too difficult to implement just for a web browser. Full SGML systems solve large, complex problems that

Sometimes it seems you spend more time manipulating XML files than you do writing Java code, so it makes sense to have one or two XML wranglers in your toolbox. In this article, Laurent Bovet gets you started with XmlMerge, an open source tool that lets you use XPath declarations to merge and manipulate XML data from different sources.
As a Java developer you use XML every day in your build scripts, deployment descriptors, configuration files, object-relational mapping files and more. Creating all these XML files can be tedious, but it's not
The Extensible Markup Language (XML) describes a class of data objects called XML documents which are stored on computers, and partially describes the behavior of programs that process these objects. XML is a subset or restricted form of SGML, the Standard Generalized Markup Language (ISO 8879). The goal of XML is to enable generic SGML to be served, received, and processed on the Web in the way that is now possible with HTML. XML has been designed for ease of implementation and for interoperability with both SGML and HTML.
XML customizes SGML in a
Tree controls provide a hierarchical view of data and XML provides a way to structure data hierarchically, so viewing XML data as a tree structure is a natural fit. But browsers don't provide a tree control. Instead, use this mix of XML, XSLT, JavaScript, and CSS to produce an extensible HTML tree control.
After writing the Build an Object-Oriented Tree Control Using JavaScript article, it occurred to me that using XML as the data source for the tree would be a natural fit. I wanted to create a solution that was both maintainable and extensible. That
VTD-XML is a new open source XML processing API that provides a great alternative to SAX and DOM that doesn't force you to trade processing performance for usability. Find out why this Java-based, non-validating parser is faster than DOM and better than SAX.
VTD-XML is a new, open-source, non-validating, non-extractive XML processing API written in Java. Different from current XML processing technologies, VTD-XML is designed to be random-access capable without incurring excessive resource overhead. One key optimization of VTD-XML is non-extractive
Welcome to Processing XML with Java, a complete tutorial about writing Java programs that read and write XML documents. This is the most comprehensive and up-to-date book about integrating XML with Java (and vice versa) you can buy. It contains over 1000 pages of detailed information on SAX, DOM, JDOM, JAXP, TrAX, XPath, XSLT, SOAP, and lots of other juicy acronyms. This book is written for Java programmers who want to learn how to read and write XML documents from their code. The paper version is published by Addison-Wesley, and can be found at fine

XQuery is a query language (with some programming language features) that is designed to query collections of XML data. It is semantically similar to SQL.
XQuery 1.0 was developed by the XML Query working group of the W3C. The work was closely coordinated with the development of XSLT 2.0 by the XSL Working Group; the two groups shared responsibility for XPath 2.0, which is a subset of XQuery 1.0. XQuery 1.0 became a W3C Recommendation on January 23, 2007.
"The mission of the XML Query project is to provide flexible query facilities to extract data
W3C XML Schema is one to specify the structure of and constraints on XML documents. As usage of W3C XML Schema has grown, certain usage patterns have become common and this article, the first in a series, will tackle various aspects of the creation and usage of W3C XML Schema. This article will focus on techniques for building schemas which are flexible and which allow for change in underlying data, the schema, or both in a modular manner.
Designing schemas that support data evolution is beneficial in situations where the structure of XML instances
An XML Schema Definition (XSD) is an instance of an XML schema written in XML Schema. An XSD defines a type of XML document in terms of constraints upon what elements and attributes may appear, their relationship to each other, what types of data may be in them, and other things. It can be used with validation software in order to ascertain whether a particular XML document is of that type, and to produce a PSVI.
XSDs were the first W3C-recommended XML schemas to provide a namespace and datatype aware alternative to using XML's native Document Type
XML Signature (also called XMLDsig, XML-DSig, XML-Sig) is a W3C recommendation that defines an XML syntax for digital signatures. Functionally, it has much in common with PKCS#7 but is more extensible and geared towards signing XML documents. It is used by various Web technologies such as SOAP, SAML, and others.
XML signatures can be used to sign data–a resource–of any type, typically XML documents, but anything that is accessible via a URL can be signed. An XML signature used to sign a resource outside its containing XML document is called a
More and more devices including PCs, PDAs, mobile phones, and various kinds of appliances are being connected to the network and many people are trying to use them for network applications such as e-commerce. One of the most important requirements for a network application is the security of data exchanged through the network.
XML has been widely accepted as a standard format for data exchange in Internet and security mechanisms for XML documents and messages must be provided in the first place. The security mechanisms have to be implemented in Java
Description
This work defines the XML Pointer Language (XPointer), the language to be used as a fragment identifier for any URI-reference that locates a resource of Internet media type text/xml or application/xml.
XPointer has been split into a framework for specifying location schemes, and three schemes: element(), xmlns() and xpointer(). The framework and the first two schemes form the XPointer Recommendation, and provide a minimal inventory of mechanisms.
The xpointer() scheme, which is based on the XML Path Language (XPath), is still under
This specification defines the XML Pointer Language (XPointer), the language to be used as the basis for a fragment identifier for any URI reference that locates a resource whose Internet media type is one of text/xml, application/xml, text/xml-external-parsed-entity, or application/xml-external-parsed-entity [IETF RFC 2376]. This specification does not constrain the syntax or semantics of URI references to resources of other media types, although it provides extension facilities that may be used with other types.
XPointer supports addressing into
Unlike its companions XLink and XML Base, XPointer has retreated from Candidate Recommendation to Last Call Working Draft status.
Daniel Veillard noted that:
"This second Last Call has been made necessary by a change required to XPointer to insure that URI References built using XPointer are context independant. This specific addition is detailed in section 5.2.1 of this XPointer Working Draft."
The problem appears to revolve around namespaces, as the spec now adds:
"For any XPointer part that uses the xpointer scheme, the evaluation context
XPointer, a language for referring to locations of fragments of an XML document, brings similar (but more expansive) capabilities to using URLs with hashes in order to link to a particular point in an HTML document. Learn more about this language, including the controversy it has stirred up and the alternative schemes it has spawned.
The XPointer Framework [W3C Recommendation] defines a language that you can use to refer to fragments of an XML document. You're perhaps already familiar with how you can use URLs with hashes ("#") in them to link to a
Abstract
This document is a liaison statement from XML Linking Working Group to the XML Information Set working group. Because the XPointer specification under development in the XML Linking WG must refer to structural parts of XML documents, the structure it addresses must be explicit. Document structure specifications such as DOM and the XML Information Set may wish to consider the XPointer requirements in order to insure interoperability when used with XPointer and XLink. Thus we have set out in this document, some constraints we believe XPointer
