Detailed Description

Class XPATH keeps track of what we are working on within a PTREE.

Then if an exception is thrown, the place within the tree that gave us grief can be reported almost accurately. To minimally impact speed, merely assign const char* pointers during the tree walking expedition. The const char* pointers must be to C strings residing either in the data or code segment (i.e. "compiled in") or within the XML document, but not on the stack, since the stack is unwound during the throwing of the exception. The XML document will not immediately vanish since we capture the xpath (using function Contents()) before the XML document tree (PTREE) is destroyed.
