Tee hee, so much for Plone's amazing standards compliance ;-) Looking closer, it was actually the ids that were causing the problem. Ids can't start with _ in HTML 4.01 but it is perfectly legitimate in XHTML. So, Plone is compliant with XHTML. I have been customising the templates in the past and it takes a lot of work, on many templates, all over the place. Well, your filter only changes things that are in main_template... ??? The filter runs on the HTTPResponse object, thus changing all the HTML output, not just the ouput from main_template. In addition, I'd like to keep the content stored in the ZODB as XHTML. Why? Well, looking forward, if the NZ government guidelines finally support XHTMl, we'll just need to remove the filter. In addition, we want to be able to transform the content with XSL transformations. Finally, Kupu and Epoz are good at producing XHTML, but don't support HTML 4.01. And, last but not least, I can upgrade Plone without having to rework all my templates now. Bwahahaha... the other great myth ;-) Before, i had to modify 10-12 templates at least. Between Plone 2.0.4 and 2.0.5, these templates got changed and I had to spend 20 hours or so reworking the HTML ouput and testing. Now, when we move to Plone 2.1, I hope to do no work at all. I don't think it is a myth :-) Cyrille ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )

Hi all,
I got the filter to work. I just added 3 lines of code in
ZPublisher.HTTPResponse.HTTPResponse (thanks for your suggestion,
Dieter):
doctype_str_search = re.compile(r'!DOCTYPE.*')

-//W3C//DTD HTML 4.01 Transitional//EN
http://www.w3.org/TR/html4/loose.dtd;', body)

You can't be serious, right?
The above do NOT suddenly make it HTML 4.01, I'm 90% sure ;-)
Really, you should be customising the templates to serve HTML in the
format you need rather than persuing this insanity...

[Zope] Re: HTML post processing in Zope
Hi Chris,
Well, you'd better believe it :-)
It works for me so far. But if you have specific examples that I can use
to improve the filter, they would be very welcome.
Two additional things that I had to do to be HTML 4.01 compliant:
* replace html ... with html (remove the namespace information)
* remove the login portlet: Plone uses form parameters __ac_name and
__ac_password, which the W3C validator rejects as invalid.
I have been customising the templates in the past and it takes a lot of
work, on many templates, all over the place. In addition, I'd like to
keep the content stored in the ZODB as XHTML. And, last but not least, I
can upgrade Plone without having to rework all my templates now.
But if you have a better idea, your suggestions are most weclome.
Back to the insanity ;-)
Cheers.

It works great except that... it breaks the WebDAV ( I can still connect
but can't see the files).
I'd like to add a condition there: if WebDAV, don't do anything. But all
I have is the body. No port, for instance...
I thought of testing: if content type = 'text/html', byt WebDAV will
probably be of that type.
Any suggestion will be wecome.

Answering my own questions: Testing for text/html does the trick as WebDAV follows some other content type (probably text/xml). It works great!

Thanks for your help! Yes, it's irritating isn't it? I've worked on an NZ government site before, but in PHP. You can use Apache to parse the HTML, mod_python allows you to use PythonOutputFilters, where you can use a regexp to clean up the HTML. I'd personally think that using Apache would be faster, but I may be wrong. -- Phillip Hutchings http://www.sitharus.com/ [EMAIL PROTECTED] / [EMAIL PROTECTED] ___ Zope maillist - Zope@zope.org http://mail.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope-dev )
