[jdom-interest] Getting comments in a Document

[Edelson, Justin]

Are you creating the comments in your XSLT with the <xsl:comment> tag?

The XSLT spec defines the default rule for comments to be to strip them.
See http://www.w3.org/TR/xslt#built-in-rule

Jason,
Thanks for the help. I changed my code to getDescendants() and it worked
correctly. I can now see the comments.

But, the next problem surfaces. I find an Element node, create a new
Document with that node as the root, and transform it into an HTML
stream.
The transformed HTML stream does not have comments in it. There is also
no
indication from the feedback generated during the transformation that
comments are being seen.  Here is my code:

    Iterator commentIterator;
    Filter comments = new ContentFilter( ContentFilter.COMMENT );
    File inXslt = new File( xsltfn );
    File inDir = new File( sourceDir );
    File in = new File( inDir, fname );
    Document doc = JdomAssistant.docMaker( in );
    for ( commentIterator = doc.getDescendants( comments);
         commentIterator.hasNext();)
    {
        Comment comment = (Comment) commentIterator.next();
        System.out.println( "comment: " + comment.getText() );
    }
    Element root = doc.getRootElement();
    Element prelreqs = (Element) XPath.selectSingleNode( root,
           "/dmodule/content/proced/prelreqs");
    Document prelDoc = new Document( (Element) prelreqs.clone() );
    XSLTransformer tran = new XSLTransformer( inXslt );
    Document newPrelDoc = tran.transform( prelDoc );
    System.out.println( "After transform: " );
    for ( commentIterator = newPrelDoc.getDescendants( comments);
          commentIterator.hasNext();)
    {
        Comment comment = (Comment) commentIterator.next();
        System.out.println( "comment: " + comment.getText() );
    }

I see the comments in the first for loop, and none in the second. Does
the
default transformer pass comments through?

getContent() only works one level deep.  getDescendants() might work 
better for you (it returns a lazy Iterator), or an XPath like
//comment().
