call
Evaluate the expression- Parameters:
context
- the dynamic evaluation contextarguments
- the values of the arguments, supplied as SequenceIterators- Returns:
- the result of the evaluation, in the form of a SequenceIterator
- Throws:
XPathException
- if a dynamic error occurs during the evaluation of the expression
-
resolveQName
Static method to resolve a lexical QName against the namespace context of a supplied element node- Parameters:
lexicalQName
- the lexical QNameelement
- the element node whose namespace context is to be used- Returns:
- the result of resolving the QName
- Throws:
XPathException
- if the supplied value is not a valid lexical QName, or if its namespace prefix is not in scope
