convert string to xml {{{Aparently your <xsp:expr>result</xsp:expr> returns a string and not and XML stream. You can use JTidy to convert your String to an XML stream. It's classes are available in Cocoon! Here's a code snip out of an XSP page that converts a POST from a brower based html editor to an XML stream.

• <xsp:structure>

  • <xsp:include>org.w3c.tidy.Tidy</xsp:include> <xsp:include>java.io.ByteArrayInputStream</xsp:include>

  </xsp:structure> <page>

  • <xsp:logic>

    • String strContent = request.getParameter("content");

      ByteArrayInputStream in = new ByteArrayInputStream( strContent.getBytes() ); org.w3c.dom.Document doc = null; org.w3c.tidy.Configuration conf = new org.w3c.tidy.Configuration(); try {

      • Tidy tidy = new Tidy(); //Do not show "parsing" messages tidy.setQuiet(true); //Do not show warnings in the Servlet Engine console tidy.setShowWarnings(false); //set the output type tidy.setXmlOut(true); //Set the encoding tidy.setCharEncoding( conf.LATIN1 ); //Set output options tidy.setBreakBeforeBR(false); tidy.setQuoteNbsp(true); tidy.setQuoteAmpersand(true); tidy.setLiteralAttribs(true); //Omit the document type in the tidy output tidy.setXmlPi(false); //parse the document tot a DOM tree doc = tidy.parseDOM(in, null);
      } catch (Exception e) {
      • //Do some error handling here
      }

    </xsp:logic> <content>

    • <xsp:expr>doc.getDocumentElement()</xsp:expr>

    </content>

You will need to tweak the Tidy parameters, but you get the idea, I guess. The DOM stream from JTidy is automatically converted to SAX by Cocoon (correct me if I'm wrong) so you can do regular transformations in the pipeline afterwards.
