Outputting Conditional Comments

ole_v2 · November 12th, 2006, 06:15 PM

I'm guessing despite my XSLT newb status that outputting something such as this is actually impossible because its not valid XML.

Code:

<![if !IE]><p>IE ignores this</p><![endif]>

Are there any workarounds?

At the moment I'm considering a PHP hack, as I'm running my XSLT via PHP anyway.

Code:

<ifNotIe><p>IE ignores this</p></ifNotIe>

Code:

$outputFromXslt = str_replace(
    $outputFromXslt, 
    array('<ifNotIe>', '</ifNotIe>'), 
    array('<![if !IE]>', '<![endif]>')
);

Yes, that's more-or-less true. You can sometimes handle "almost-XML" output by using disable-output-escaping if your processor supports it, but producing real XML output and then post-processing it as you propose is probably a cleaner solution.

OK cool, thats what I did anyway.

There should really be a literal element for this sort of thing that lets you break free from the bounds.
