Problem with own Generator and XSLT
Hello,
For a project we are working on, we are implementing our own generator,
which is supposed to combine multiple input sources (XML-FS, OODB, RDB,
...) and output one XML. We started out with the generator having all
XML hardcoded in our generator, so it would look like this:
public void generate() throws IOException, SAXException,
ProcessingException {
....
// xmlConsumerAdapter calls xmlConsumer
this.xmlConsumerAdapter.startNSElement("info", "title");
this.xmlConsumerAdapter.characters("MuX [" +
this.parameters.getParameter("OutputType", "NULL") + "]");
this.xmlConsumerAdapter.endNSElement("info", "title");
...and so on
We then copied a part of our xml output (The part containing the
navigation) and moved it to a xml file on the filesystem.
No matter what way we tried to include this file however and send it to
the xml consumer, no xsl transformation of any elements below the
included navigation occurred.
We then implemented a way of turning compents in the xml output of, so
cocoon/myproject?nav=0 would simply not include the nav file, then all
other elements would be transformed.
Is this a bug in cocoon? (We reported it as #3057) What would be the
correct to send xml code from the filesystem to xmlConsumer?
Here is what we tried:
1.
//nav File is a String to the existing nav file
Source is = resolver.resolve(navFile);
is.toSAX(this.xmlConsumer);
2.
XMLReader xr = XMLReaderFactory.createXMLReader();
xr.setContentHandler(super.xmlConsumer);
xr.parse(new InputSource(new FileReader(navFile)));
Thanks a lot for your help!
martin

Thank you so much, its working perfectly now. It must have been the
startDocument() that caused the transformation to stop.
I just closed the bug, sorry if anyone wasted time on my error.
thanks once more

AW: Problem with own Generator and XSLT
Posted by Carsten Ziegeler <cz...@sundn.de>.
Hi,
1. did you try to read and transform your file using the standard
file generator? (in sitemap: <map:generate src="file.xml"/>)
2. If you include an xml source inside your generator into your
stream, your first approach (using toSAX()) is the way to go,
but when using toSAX() (or any other method), all sax events
for parsing this document are send, including the startDocument()
and endDocument() event.
So if you include this, you have to ignore those two sax events.
For exactly this purpose exists the
org.apache.cocoon.xml.IncludeXMLConsumer
class.
If 1. does not work, it may be that your stylesheet is the source
of error.
If you still have problems, include your xml and xsl file if possible.
