Xpp -- XML pull parser, xpp3 is a very fast XML Parser and xpp of the third edition. Xpp2 is the second version of xpp. Xpp3 is the successor of xpp2 and implements the xmlpull API defined by the http://www.xmlpull.org. Xpp3 can only be used to parse XML, but does not support adding a node tree. According to a comparative test, xpp3 is six times faster than dom4j, that is, 1/6 of the time is used.
Xpp3 uses the Apache 1.1 variant license protocol.
