small XML parser for Java
NanoXML is a (actually more than one) small XML parser for Java. It provides the Java packages net.n3.nanoxml.*, net.n3.nanoxml.sax.* and nanoxml.* in nanoxml2.jar, nanoxml2-sax.jar and nanoxml2-lite.jar. The package nanoxml.* is source compatible with NanoXML 1 but is more restrictive on what it will parse than NanoXML 1.
