Returning HTML String intact from Extension Function

[David Bigwood <Da...@chordiant.com>]

I have a problem running a Java extension function from an XSL stylesheet in
Xalan.
The Java Class I am calling returns me a String, which contains HTML tags.
I wish to use the HTML as supplied to change the output of the XSL
stylesheet.

Unfortunately, I believe the string is escaped as/before it is returned to
me and instead of getting, e.g.

<h1>Hello</h1>

I get something like:

&lt;h1&gt;Hello&lt;/h2&gt;

Does anyone know how I can stop the string being encoded and/or make use of
the HTML as HTML?

Thanks in advance
-David

David-

As Gary said, the best thing to do is to return the <H1> tag itself,
however I ran into a situation where I needed to include the contents of
an HTML file that was not well-formed XHTML.  Here's the way to
accomplish this:

There is a supported way to mimic the <xsl:value-of ...
disable-output-escaping="yes" /> behavior in extensions.  Here's the
code to do this:

        try {
            if ( disableOutputEscape ) {
                context.outputToResultTree( context.getStylesheet( ) ,
                  elementFactory.createProcessingInstruction(
                    Result.PI_DISABLE_OUTPUT_ESCAPING , null ) ) ;
            }

            context.outputToResultTree( style , content ) ;

            if ( disableOutputEscape ) {
                context.outputToResultTree( context.getStylesheet( ) ,
                  elementFactory.createProcessingInstruction(
                    Result.PI_ENABLE_OUTPUT_ESCAPING , null ) ) ;
            }
        } catch ( java.net.MalformedURLException mue ) {
        } catch ( java.io.FileNotFoundException fnfe ) {
        } catch ( java.io.IOException ioe ) {
        }

The variable "disableOutputEscape" is determined by the value of an
attribute in the extension function, "style" is the Stylesheet being
used (determined by context.getStylesheet( )), "content" is a String of
the content I want to send, and "elementFactory" is (an inappropriate
name for) a DOM Document object simply used to create the processing
instructions.  "Result" is javax.xml.transform.Result.

HTH,
--Jason

Return what you'd like to see in the output.  Namely, an <h1> element
node with a "Hello" text node child.
