You would have to continually scan back through the document until  
you encounter a "<!--" or a "-->".  In the first case, you  
encountered the end of a comment, in the second, the end of a tag.   
Now for the question.  What about:

<!--<badtag>yippie<!--<reallybadtag>!</reallybadtag></badtag>-->

First, not entirely up on my XML, but is the above legal?  If so,  
then finding the end (beginning in document order) of the comment  
becomes lots of fun.
