Re: custom transformer
Thanks for the tip, but after playing around with it I realize that I'm mixing up two different things. If I throw the SAXException, the rest of the original pipeline is still executed, after which the error pipeline is executed. What I want is to stop the original pipeline from the moment the exception is thrown, and thus not do any other transformations (this is required 'cause one transformer does some FTP stuff). To make things clearer : I'm starting from an XSP using esql to fetch fields from database. When an error occurs on database level (esql:error-results), the current pipeline may NOT be executed any further, but a new pipeline should be activated (this is why I thought I could invoke the error pipeline). Any suggestions ? Could I use redirects inside the esql:error-results tag ? Or is there a better solution ? Thanks again !

If you can't throw a ProcessingException in setup, wrap a SAXException around your real exception. In the case of AbstractDOMTransformer, transform() doesn't declare any exceptions (which it should IMO), so you might have to rewrite the notify() method in your transformer so that your transformation operation can throw exceptions. -Bertrand - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Custom transformer
From: Lionel Crine [EMAIL PROTECTED] 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:elemDOCUMENT/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 ? 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. -- Konstantin Sax Characters method only returns DOCUMENT, but I also need the tags.

Re: Custom transformer
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?

For an example you can take a look at classes in src/java/org/apache/cocoon/transformation/helper/ package. 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.
