The URLs which has been using traditionally are simple and easy but those are quite limited a URL points at a complete single document, it is like linking to the third sentence in a seventeenth paragraph in a document this can be done if the author of the document has written access to the document being linked to, though the author does the linking it can insert named anchors into the targeted document so it is almost inconvenient always,  Xpointer defines an addressing scheme for individual parts of an XML document. And application that needs

Before discussing its important learn few basic concepts of data binding. In spite of what element is used for binding and the kind of data source, every binding need to follow a model demonstrated by following figure: Data binding is nothing but the bridge between binding target and binding source. We are going to discuss about the WPF data binding concepts: There are four components in each binding and these are binding target object, target property, binding source, and path to value in binding source to use. The best example

The W3C recommendation allows any digital data to be signed, and this includes an XML document, an XML element of a document, and the content of an XML element as particular cases. When we talk about an XML signature, we are actually referring to an XML document, which contains the Signature (defined in the namespace http://www.w3.org/2000/09/XMLdsig#) as one element (which may be the root element). But the document may also contain other elements, among which the most important are, of course, the original data objects being signed. Depending on

Traditional URLs are simple and easy to use, but they’re also quite limited. For one thing, a URL only points at a single, complete document. More granularity than that, such as linking to the third sentence of the seventeenth paragraph in a document, requires the author of the targeted document to manually insert named anchors at the targeted location. The author of the document doing the linking can’t do this unless he or she also has write access to the document being linked to. Even if the author doing the linking can insert named anchors into

XML data binding refers to the process of representing the information in an XML document as an object in computer memory. This allows applications to access the data in the XML from the object rather than using the DOM to retrieve the data from a direct representation of the XML itself. An XML data binder accomplishes this by creating a mapping between elements of the XML schema of the document we wish to bind and members of a class to be represented in memory. When this process is applied to convert an XML document to an object, it is called

If you browse the Web at all, you probably use forms more often than you realize. Nearly all on-line interaction (as opposed to static text delivery) takes place through some kind of form. To enhance the use of forms on the Web, the World Wide Web Consortium (W3C) sponsored the development of XForms. Instead of further altering the existing forms language that is part of HTML, the W3C membership agreed that a new approach was necessary. Several years later, this has become XForms 1.0, an official Recommendation of the W3C. Like XHTML, SVG, and

XLink Attribute Usage Patterns While the XLink attributes are considered global by virtue of their use of the namespace mechanism, their allowed combinations on any one XLink element type depend greatly on the value of the special type attribute (see [XLink Element Type Attribute (] for more information) for the element on which they appear. The conformance constraint notes in this specification detail their allowed usage patterns. Following is a summary of the element types (columns) on which the global attributes (rows) are allowed, with an

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

XLink Elements and Attributes XLink offers two kinds of links: Extended links Extended links offer full XLink functionality, such as inbound and third-party arcs, as well as links that have arbitrary numbers of participating resources. As a result, their structure can be fairly complex, including elements for pointing to remote resources, elements for containing local resources, elements for specifying arc traversal rules, and elements for specifying human-readable resource and arc titles. XLink defines a way to give an extended link special

XLink Markup Design This section describes the design of XLink's markup vocabulary. Link markup needs to be recognized reliably by XLink applications in order to be traversed and handled properly. XLink uses the mechanism described in the Namespaces in XML Recommendation [xname] to accomplish recognition of the constructs in the XLink vocabulary. The XLink namespace defined by this specification has the following URI: http://www.w3.org/1999/xlink As dictated by [xname], the use of XLink elements and attributes requires declaration of the

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

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 XML Namespaces Recommendation seems to be causing a great deal of confusion. This note attempts an alternative explanation of the mechanism described in the Recommendation which I hope will be less confusing. In the data model implied by XML, an XML document contains a tree of elements. Each element has an element type name (sometimes called the tag name) and a set of attributes; each attribute consists of a name and a value. Applications typically make use of the element type name and attributes of an element in determining how to process the

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

Schema component is the generic term for the building blocks that comprise the abstract data model of the schema. An XML Schema is a set of ·schema components·. There are 13 kinds of component in all, falling into three groups. Primary Components: The primary components, which may (type definitions) or must (element and attribute declarations) have names are as follows: 1.Simple type definitions 2.Complex type definitions 3.Attribute declarations 4.Element declarations Secondary Components: The secondary components, which must have

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

W3C Schema can quickly become complex and difficult to determine if they are validating the correct vocabulary. The addition of embedded Schematron schema only makes this problem worse. Schema Unit Test (SUT) introduces a framework for testing XML Schema. This framework has two parts. The first is a namespace and vocabulary for embedding test cases into sample XML documents, designed to highlight what is legal and what is not legal in the vocabulary defined in the schema under test. This aspect is independent of what schema language is used and

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

This section of the requirements involves the type and variety of data locations, or "targets", that an XPointer must be able to identify. These requirements make frequent reference to XML information objects such as elements, attributes, PIs, and characters. The formal definition of these objects, their relationships such as ordering, containment, and attribution, and their precise correspondence to XML syntax constructs are the domain of the XML Information Set Working Group. For more detail on the relationship, see the XML Linking Working Group's

XPointer is based largely upon a widely-used technology, the Text Encoding Initiative "extended pointer" [Sperberg-McQueen 1994], [Ide 1995]. Extended pointers provide axes for navigating within trees and a rudimentary predicate language for selecting nodes along axes, and have been implemented in several SGML-based browsing systems. TEI extended pointers introduced "location terms" including root, here, id, child, descendant, ancestor, previous (sibling), next (sibling), preceding, following, and pattern (content matching by regular expressions) --
