Name
XPathExpression: a compiled XPath query â Firefox 1.0, Safari 2.01, Opera 9: Object â XPathExpression
Methods
-
evaluate( )
Evaluates this expression for a specified context node.
Description
An XPathExpression object is a compiled representation of an XPath query,
returned by Document.createExpression(
)
. Evaluate the expression against a particular document
node with the evaluate( )
method.
If you need to evaluate an XPath query only once, you can use
Document.evaluate( )
, which
compiles and evaluates the expression in a single step.
Internet Explorer does not support the XPathExpression object.
For IE-specific XPath methods, see Node.selectNodes( )
and Node.selectSingleNode( )
.
