parse_xml
===============================================================================
This is an example of using the XML parsing facilities of
XML-RPC For C/C++, in particular its libxmlrpc_xmlparse library.
Feed XML (any XML - doesn't have to be XML-RPC) to this program as
standard input. It parses it and tells you what it sees.
Example:
$ ./gen_sample_add_xml | ./parse_xml
