But you should really consider using Transformer as Jaxier suggested. Thats
what "filters" XML data in Cocoon so acts as a Filter.
If you need to do this in Java (write your own Transformer [Filter]), you
can take a look at one of the simplest Transformers
in Cocoon sources: CleaningTransformer
cocoon-sax/src/main/java/org/apache/cocoon/sax/component/CleaningTransformer.java
You just consume SAX events and generate new ones :)
