Again and again, if you have XML as a string and want to push it over
the pipeline, and have it recognized as 'XML' (SAX events), you need to
parse it, using an XML parser. Using disable-output-escaping is a trick
of which I'm very suprised it even works inside Cocoon, and certainly
wouldn't like to see used in the Cocoon samples.
There are various solutions:
* parse the XML in the flowscript and pass the result as a DOM or a
SaxBuffer to the view
* embed (x/c)include statements in the template that address the
to-be-embedded XML using the module source
* or use a class like the StringXMLizable attached with this message,
and use it like this in the template:
#{mypackage.StringXMLizable.new(/myobject/mystring)}
this essentially wraps a string (here addressed as /myobject/mystring)
and turns it into an XMLizable object. This of course supposes that the
string contains well-formed XML.
