Table 11-1 lists small XML parsers that can be used with the MIDP platform. Each parser will be explored in subsequent sections, but the table here gives you a quick way of comparing parsers. Each of these parsers is released under some type of open-source software license as listed in the License column. The Size column shows the approximate size of the compressed class files for the parser. The Type column describes the parsing paradigm using one of the following:

• "Pull" indicates that the programmer repeatedly calls a method on the parser to propel it through a document.

• "Push" means that the parser runs through the entire document by itself, invoking callback methods in your code when important events happen. SAX parsers implement the push paradigm.

• "Model" indicates that the parser builds some internal representation (in memory) of the document. After parsing is finished, your code can examine this model and pull out element data.

  Table 11-1: Small XML Parsers

  NAME	URL	LICENSE	SIZE	MIDP	TYPE	SAX
  kXML	http://kxml.enhydra.org/	EPL	34KB	yes	pull	no
  MinML	http://www.wilson.co.uk/xml/minml.htm	BSD	13KB	no	push	1.0
  NanoXML	http://nanoxml.sourceforge.net/	zlib/libpng	10KB	patch	model	1.0 optional
  TinyXML	http://www.gibaradunn.srac.org/tiny/	GPL	13KB	no	model	no
  wbxml	http://www.trantor.de/wbxml/	GPL	19KB	no	push	1.0

The MIDP column indicates whether or not the parser source code compiles without modification on the MIDP platform. Finally, the SAX column tells what version of SAX the parser supports.

Table 11-2 provides more information about each type of license, listing both the license name and a URL that provides more information.

In the following sections, I'll describe each parser. I'll explain how to make the parser compile for MIDP, as well as how each parser can be used from a MIDlet.
