Hi Derrick,

That doesn't sound too bad at all to me.  I created a single utility 
function that handles that for any tag I need to inject:

    void setEndTag(Tag tag)
    {
        TagNode endTag = new TagNode();
        endTag.setTagName("/" + tag.getTagName());
        tag.setEndTag(endTag);
    }

That works like a charm!

Thanks,
Tom
