Detailed Description

This component is used to parse a complex XPath 2.0 expression or pattern into an expression tree for easy evaluation.

An expression can be compiled once and evaluated many times against the same or different DOM trees (from XML or JSON). An expression supports XSLT evaluation via the use of the XSLT context node and access to active variable values (see P6R::p6IXpathVariables).
