public class FuncHere
extends org.docx4j.org.apache.xpath.functions.Function
The 'here()' function returns a node-set containing the attribute or processing instruction node or the parent element of the text node that directly bears the XPath expression. This expression results in an error if the containing XPath expression does not appear in the same XML document against which the XPath expression is being evaluated. Mainpart is stolen from FuncId.java This does crash under Xalan2.2.D7 and works under Xalan2.2.D9 To get this baby to work, a special trick has to be used. The function needs access to the Node where the XPath expression has been defined. This is done by constructing a FuncHere which has this Node as 'owner'.
