MDN’s new design is in Beta! A sneak peek: https://blog.mozilla.org/opendesign/mdns-new-design-beta/

An XPathExpression is a compiled XPath query returned from document.createExpression(). It has a method evaluate() which can be used to execute the compiled XPath.

Methods

  • evaluate (contextNode, type, result) - provide a context node/document, XPathResult constant, and XPathResult to store the query or null to return a new XPathResult.
  • evaluateWithContext (contextNode, contextPosition, contextSize, type, result) - provide a context node/document, context position, context size, XPathResult constant, and XPathResult to store the query or null to return a new XPathResult.
