hi,
It seems you did not understood my problem, or I did not explain well
since I am not very good in ingleesh :)
(Or perhaps I did not understood your answer too;)
I don't want to create CSS code, I want to read CSS code.
What I have to do is to get in a var, the CSS code that is in the head of the
document, then remove it (or it will produce an error), and then to put each
css code block in each tag of the document in theirs 'style' attribute.
I had a quick look at HTML_CSS and it seems it is only designed to create CSS
code and not to read it yet. Am I wrong?
Here is an exemple, I have to transform the code of the file "what_I_have.svg"
to a string "$what_I_want" before to feed IM with it.
Cheers
