Returns a xml.DomNodeList object containing all DomNode objects matching an XPath 1.0 expression.expr is the XPath1.0 expression, nslist is a list of prefixes bounded to namespaces in order to resolve qualified names in the XPath expression. This list must be filled with an even number of arguments, representing the prefix and its corresponding namespace.
selectByXPath( "//d:Record", "d", "http://defaultnamespace") selectByXPath( "//ns1:Record", NULL) selectByXPath( "//ns1:Records/ns2:Record", "ns1", "http://namespace1", "ns2", "http://namespace2")
Invalid example:
selectByXPath( "//ns1:Record", "ns1")This example is invalid because the namespace definition is missing.

A namespace must be an absolute URI (ex 'http://', 'file://').
In case of error, the method throws an exception and sets the STATUS variable with the appropriate error number.
