Custom transformer
I have an xml document :
<?xml version="1.0" encoding="UTF-8"?>
<xsp:page xmlns:xsp="http://apache.org/xsp"
xmlns:my_NS="http://www.my_NS.com/my_NS/query/1.0">
<my_NS:document>
<my_NS:query VERSION="2.0" RESULTSPACE="R1">
<my_NS:property NAME = "DocType">
<my_NS:elem>DOCUMENT</my_NS:elem>
</my_NS:property>
</my_NS:query>
</my_NS:document>
</xsp:page>
In my transformer I need to get all that si between "<my_NS:document>
</my_NS:document>" tag and put it in a string or a String buffer.
Which method can do that for me ?
Sax "Characters" method only returns DOCUMENT, but I also need the tags.

I saw that and I've already implemented this method.
Where I'm stuck is that these methods return a "void" so how can I store my
tags and text in a StringBuffer?

If you inherit from the AbstractSAXTransformer, you only have
to invoke startSerializedXMLRecording() before the first element
arrives that you want to have included in your string.
And at the end invoke endSerializedXMLRecording() and you get
all the XML inbetween as a string.
Have a look at some other transformers using the AbstractSAXTransformer
for samples.

You should implement almost all the methods of ContentHandler interface,
such as:
startDocument()
startElement()
characters()
endElement()
endDocument()
etc. and store everything you need into a String buffer.
For an example you can take a look at classes in
src/java/org/apache/cocoon/transformation/helper/ package.
