XPath-XLink-XPointer

In the course XPath-XLink-XPointer the participants learn to apply the XPath, XLink and XPointer specifications to localizing and linking fragments in XML documents.

XML Overview

The course starts with an overview of the XML document structure and components of XML documents. This focusses on the role of elements, attributes and text. The difference between well-formed and valid documents is also discussed.

XPath Expressions

Next XPath is addressed with which nodes in an XML document that meet certain conditions can be selected. The syntax of XPath expressions with predicates, node selection and functions is discussed.

XPath Axes

And also the various search axes that XPath has are treated.

XPath Data Types

XPath uses the data types from XML Schema and these are explained as well.

XLink

Then attention is paid to XLink with which XML fragments can be linked together. After discussing the limitations of HTML links, the Simple and Extended links in XLink are treated. Also Link Behavior and the Semantic and Traversal attributes of links are discussed.

XPointer

Finally XPointer is on the course schedule with which the internals of XML documents can be addressed. The relationship to and the differences with XPath are explained.

Audience Course XPath-XLink-XPointer

The course XPath-XLink-XPointer is intended for anyone who wants to learn how to search XML with XPath and how to make XML connections with XLink and XPointer.

Prerequisites Course XPath-XLink-XPointer
