You should know a little bit about XML, XPath. The XPointer specification relies also on XML Schema. We recommend you our tutorials for XML and XPath. and interactive XLab: XLab - xpath expressions, XLab - xpath axes, XLab - xsl:value-of, XLab - string functions.

XPointer is intended to point to XML-based media types. Standard excerpt: "The framework is intended to be used as a basis for fragment identifiers for any resource whose Internet media type is one of text/xml, application/xml, text/xml-external-parsed-entity, or application/xml-external-parsed-entity."

Some notes about XLinks and XPointers

Introduction about XLink and XPointer.

You already know how to link XML documents together with XLink, and isolate specific nodes or node collections with XPath. Now uncover the third and final piece of the XML linking jigsaw - XPointer, an experimental technology from the W3C, which allows you to create XML links to specific points or ranges within an XML document.

A brief rundown of XLink and XPointer from an email from Eve Maler that has since been posted on the Oasis site.

The issuing of patents on software has been an industry hot topic for a while. Now it's the XML community's turn to get burned. The XML-Deviant reports this week on a Sun patent causing consternation on XML-DEV.

The W3C’s new XML Pointer (XPointer) standard provides a method for identifying pieces or fragments of an XML document. XPointer extends the XPath standard and reuses many of the same concepts, evaluation rules, and syntax. But there’s more to it than just that.

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 of Internet media type text/xml or application/xml.

XPointer is a W3C proposed standard for the addressing of arbitrary fragments of XML documents. XPointer extends XPath, which is used to address nodes, and adds support for single positions within a text node (the so-called points) and ranges within and across element nodes.

The W3C XML Linking Working Group has announced the release of XML Pointer Language (XPointer) Version 1.0 as a W3C Candidate Recommendation. The CR replaces the second last-call Working Draft version of January 08, 2001, and is open for public comment through March 4, 2002. XPointer is "built on top of the XML Path Language (XPath), which is an expression language underlying the XSL Transformations (XSLT) language.

The W3C's XPointer, a language used to reference XML fragments, has entered Candidate Recommendation phase, where implementation experience is solicited from developers.

A software component that incorporates or uses an XPointer processor because it needs to access XML subresources. The occurrence and usage of XPointers, and the behavior to be applied to resources and subresources obtained by processing those XPointers, are governed by the definition of each application's corresponding data format (which could be XML-based or non-XML-based). For example, HTML Web browsers and XInclude processors are applications that might use XPointer processors.

This is an overview about XPointer on PDF format.

After years of work, the World Wide Web Consortium (W3C) Tuesday gave a thumbs up to XML Pointer Language (XPointer), providing a way to identify and point to segments of an XML (define) document.

The XML Linking WG has just published four XPointer Working Drafts, representing the dissection of XPointer into a general framework and multiple independent schemes: element(), xmlns(), and xpointer().

Unlike its companions XLink and XML Base, XPointer has retreated from Candidate Recommendation to Last Call Working Draft status.

The XML Pointer Language (XPointer) is the language to be used as the basis for a fragment identifier for any URI reference that locates a resource of Internet media type text/xml or application/xml.

XLink and XPointer seem ready to move forward after Daniel Veillard released the decisions of the XML Linking Working Group regarding the comments on the XLink and XPointer CRs.

The much delayed XPointer specification has broken into four pieces, including an XPointer Framework and three schemes - xmlns(), element(), and xpointer(), with all but the last in Last Call.
