DESCRIPTION

The Web::DOM::XPathExpression class implements the DOM XPathExpression interface. It represents a compiled XPath 1.0 expression.

METHOD

The following method is available:

$result = $expr->evaluate ($node, $result_type, $result)

Evaluate the XPath 1.0 expression. The first argument is the context node (Web::DOM::Node object) used to evaluate the expression. The other arguments are optional. The second argument is the namespace prefix resolver, specified as either a code reference or the Web::DOM::XPathResolver object. The third argument is ignored. The method returns the Web::DOM::XPathResult object containing the evaluation result. [DOMXPATH] [DOMPERL]
