/*
Pcbnew PLUGIN for Eagle 6.x XML *.brd and footprint format.
XML parsing and converting:
Getting line numbers and byte offsets from the source XML file is not
possible using currently available XML libraries within KiCad project:
wxXmlDocument and boost::property_tree.
property_tree will give line numbers but no byte offsets, and only during
document loading. This means that if we have a problem after the document is
successfully loaded, there is no way to correlate back to line number and byte
offset of the problem. So a different approach is taken, one which relies on the
XML elements themselves using an XPATH type of reporting mechanism. The path to
the problem is reported in the error messages. This means keeping track of that
path as we traverse the XML document for the sole purpose of accurate error
reporting.
User can load the source XML file into firefox or other xml browser and follow
our error message.
Load() TODO's
