The Evolution of XPath: What’s New in XPath 3.0

by Dimitre Novatchev

This course covers XPath 3.0, a gigantic step forward from previous versions which gives the programmer unprecedented functional programming capabilities and possibilities for problem solving.

What you'll learn

XPath 3.0 is the latest version of XPath, the language for navigating XML documents. XPath is to XML documents like what SQL is to Relational Database Management Systems. The new W3C XPath 3.0 Recommendation gives us a language with amazing power resulting from its ability to define its own higher-order functions. If you think that you know XPath, but want to master version 3 of XSLT, XQuery, or future versions of XProc, XSD, Schematron, or pretty much any other modern programming language, then you need to start here. This course covers all new features of XPath 3.0: the XPath Data Model 3.0, operators, constructs, and expressions, along with the most powerful new feature - the function type. This course gives in-depth coverage of XPath 3.0 side-by-side with practical demos of their real-world applications.
