XHTML, HTML and CSS compressor

Last week Fry-IT released CheckoutableTemplates which is a templating module add-on for Zope. It includes a module called slimmer.py which can compress XHTML, HTML and CSS. The CSS had a flaw in it that I hadn't foreseen. This flaw arises when you use M$ Internet Explorer hacks like this for example:

#centercontent {
   margin-left: 259px;
   voice-family: "\"}\"";
   voice-family: inherit;
   margin-left: 271px;

Now that bug has been fixed, so I give you: The XHTML, HTML and CSS compressor It's a little application of slimmer.py so that the compressing can be tested and so that one can see the effect.


These guys have done it with JavaScript but not as good and they hope to sell each license for $7.
hey, i've been working on something like this for a while now http://flumpcakes.co.uk/css/optimiser/
I like it. It's much more clever than mine. We should combine our efforts since we obviously take two completely different approaches and that they would work together. What programming language do you use?

I was trying your nice tool for compressing an XHTML file, but the compressor removes white-spaces from an attribute value (that is between double quotation marks).

I hope you can correct this,
Peter Bengtsson
Really?? That's a bug. Can you provide me with an example where it happens and I'll try to fix it.
Nadeem Afana
Here is an example:

<example attribute="This is a test." />
Nadeem Afana
Well, add spaces between the double quotation marks.

It seems that this tool removes spaces too.
Peter Bengtsson
I see the problem. It actually saves whitespace before and after but not inside the attribute. example (. replaces whitespace):

>>> from slimmer import html_slimmer
>>> html='''<example attribute="....This is....a test...." />'''
>>> html_slimmer(html)
'<example attribute="....This is a test...." />'

You're right. It is a bug.

However, I can't find the time to work on this now. To begin with, whitespace slimming on HTML is often less important since HTML is often regenerated every time unlike CSS and Javascript which is often more static and needs only to be slimmed once per build.

I've taken note of the bug but not going to commit any time to it now I'm afraid. Thanks for spotting it!

It does not matter.

Is not there an executable version or source code of your code?
Peter Bengtsson
No but you could quite easily make one yourself with py2exe. The instructions are quite easy.
Good afternoon. I feel like a tiny bird with a big song!
I am from Cyprus and now study English, tell me right I wrote the following sentence: "More than 16,000 graphics and more than 60 card girls banked in the system defence, easyhome prepaid mastercard."

Thanks :o. Deborah.
