Hendrik Lipka / spxml

Mbed port of the Simple Plain Xml parser. See http://code.google.com/p/spxml/ for more details. This library uses less memory and is much better suited to streaming data than TinyXML (doesn\'t use as much C++ features, and especially works without streams). See http://mbed.org/users/hlipka/notebook/xml-parsing/ for usage examples.
