Subject: htmltools incorrectly parsing HTML containing server-side tags

I'm using HTML Tools 1.09 to parse HTML that contains tags that are to
be processed by the web server.  For example, here's an image tag:

<img src="<$DCGallery$>Separators/gtabseps.gif" alt="this is a
seperator">

The <$DCGallery$> will be replaced by some text when returned to the
browser by the web server.

What I'm noticing is that HTMLTools doesn't handle tags that contain an
such an embedded tag.  It seems to make an attempt at correcting what
it sees as invalid HTML.  So the above tag, after going through the
parser and having a new class added, using:

element.add_attribute('class', ' wide_content')

results in the following tag:

<img src="<$DCGallery$>Separators/gtabseps.gif"
class="wide_content"><$DCGallery$>Separators/gtabseps.gif" alt="this is
a seperator">

The image tag is closed after the new class attribute and the
server-side tag is duplicated and contains the alt attribute from the
original image tag.  Has anyone encountered such behavior?

I know that HTML Tools probably wasn't built to handle HTML with
embedded server-side tags, but for this project I need to process HTML
before being served up by the web server.  Shouldn't HTML Tools ignore
tags found within the quotes of the src attribute's value?  Is there an
option or patch that might get HTML Tools to ignore tags found within
the values of tag attributes?
