# Description

An XPathExpression represents a parsed XPath expression. They are created with XmlContainer::parseXPathExpression and evaluated with XmlContainer::queryWithXPath.

Parsed XPath expressions are useful as the cost of the expression parsing and optimization can be amortized over many evaluations.
