Description Jose Kahan 2007-10-18 08:11:12 UTC 
mod_autoindex is generating invalid XHTML markup. The xhtml namespace was 
missing in emit_preamble(). I'm including a patch against both 2.2.6 and trunk 
that fixes it.

Bug report 34519 is quite similar, but mentions other enhancements (and didn't 
include a patch). I decided to make a new bug report as I was not sure if it 
was OK to reply to one of the points given in the previous report.

Committed to trunk as r59381 (http://svn.apache.org/viewvc?rev=593778&view=rev).
Thanks for the patch.

Proposed for backport as r593818 (http://svn.apache.org/viewvc?rev=593818&view=rev).
Comment 5 Ted Guild 2007-11-13 15:43:56 UTC 
Here's an idea:

These autoindexes should not only be valid markup but promote open standards
(valid markup) by linking back to W3C's Validator.  If you are open to the idea
it would be ideal if Apache were to include W3C valid markup logos in the /icons
directory so as to distribute load of serving those icons on all the new valid
autoindex URIs.

In turn we can promote adoption of Apache 2.2, as apparently many are still 1.3,
on the Validator's results page eg  

http://validator.w3.org/check?uri=http%3A//www.w3.org/&doctype=Inline&%20outline=

We could give an alternate markup for Apache instances >2.2.N to all users or
perhaps just for sites we detect the Server: header as still Apache 1.3 or 2.0

I don't like it.

mod_autoindex is generating invalid XHTML 1.0 Transitional for fancy list.
Configuration:
IndexOptions Charset=utf-8 XHTML FancyIndexing FoldersFirst VersionSort
IndexHeadInsert "<meta http-equiv=\"content-type\" content=\"text/html; charset=utf-8\" />"

HeaderName secret.html
ReadmeName secret.html

There is problem with hr markups:
document type does not allow element "hr" here; missing one of "button", "ins", "del" start-tag

You can read it here: http://validator.w3.org/check?uri=http%3a%2f%2fgabrys.biz%2fimages%2f

Its should be outside pre markup. They are created in lines 1603-1608 and 1814-1819. Problem can be solved with replece specifed lines:
1604 -> ap_rputs("</pre><hr", r);
1608 -> ap_rputs("><pre>", r);
insert ap_rputs("</pre>\n", r); under 1813
1819 ap_rputs(">\n", r);
delete 1821, 1822, 1823

I don't test it, because I am a new FreeBSD and Apache user, and I not able to do a lot of things now :/
