iterate
Evaluate the function to return an iteration of selected nodes.- Specified by:
iteratein interfaceSequenceIterable- Overrides:
iteratein classExpression- Parameters:
context- supplies the context for evaluation- Returns:
- a SequenceIterator that can be used to iterate over the result of the expression
- Throws:
XPathException- if any dynamic error occurs evaluating the expression
