===== Description =====

This //Node.js// addon provides an //XML// parser and preprocessor.

===== Installation =====

Simply launch ''npm install xppq''.

For more details, see [[:s:i:main:|installation]].

===== Usage =====

If you want to test, launch ''npm explore xppq %%--%% node test.js''.

You can also take a look to this [[:s:s:xppqnjs:runkit.js|file]] for examples of use of //xppq-node//, and test them online on //[[:runkit:xppq:|Runkit]]//, where you can also test //xppq-node// with your own scripts.

==== Parser ====

To use the parser, you need to define a callback like this [[http://github.com/epeios-q37/xppq-node/blob/master/test.js#L77|example]]. Then you call ''xppq.parse(//stream//,//callback//);'', like [[http://github.com/epeios-q37/xppq-node/blob/master/test.js#L153|here]], with ''//stream//'', a stream providing the //XML// data you want to parse, and ''//callback//'', the previous mentioned callback.

==== Preprocessor ====
 The preprocessor (''xppq.Stream'') is a stream which takes a stream providing the //XML// data, and provides also //XML// data. So, it can be inserted between a method which takes an //XML// providing stream, like the parser above, and the stream it handles, like in this [[http://github.com/epeios-q37/xppq-node/blob/master/test.js#L157|example]].
