Hi,

I have a problem related to comments while using mod_proxy_html (version
3.0.1) with libxml2 (version 2.7.6). 
The problem consists in dropping some comments from HTML code while parsing
for URL rewrite.
Having a short look in code, I suspect the unexpected behaviour comes from
libxml, but I am not 100% sure, please forgive the out of topic comment, if
no so. 

When having an HTML document in form:

<html xmlns="http://www.w3.org/1999/xhtml ">
   <head>
       <meta name="description" content="....."/>


  here


      ..


  That piece of non-space text ends the head and open the <body>


      <!--[if lte IE 6]>
            <link href="..." rel="StyleSheet" type="text/css" media="all" />
      <![endif]-->
      <script type="text/javascript" src="..."></script>
       <!--[if lte IE 6]>
              <script type="text/javascript" src="..."></script>
       <![endif]-->
  </head>
     ...
</html>

After parsing with SAX, the first comment is dropped, only the comment found
as last child in the <head> element is preserved.
Does anyone know if dropping comments inside tags, is a problem related to
libxml?


  Except that the HTML prser seems to do its job 

paphio:~/tmp -> xmllint --html tst.html
tst.html:12: HTML parser error : Unexpected end tag : head
  </head>
         ^

<body><p>

      <!--[if lte IE 6]>
            <link href="..." rel="StyleSheet" type="text/css"
media="all" />
      <![endif]-->
      <script type="text/javascript" src="..."></script><!--[if lte IE
6]>
              <script type="text/javascript" src="..."></script>
       <![endif]-->
     ...
</p></body>
</html>
paphio:~/tmp ->

  oh and the extra space at the end of your xmlns definition makes your
data not XHTML !
