Description Raphael Champeimont 2009-06-12 20:31:27 UTC

Found under MediaWiki 1.15

To reproduce:
1. Make a page with "<math>\int_A</math>" as its only content.
2. In LocalSettings.php set wgMimeType to "application/xhtml+xml"
3. Go to the created page.
You get a parse error because an element is not closed, in this piece of code:
"<p><span class="texhtml"></p>"
The problem is the not closed span.

Comment 1 Brion Vibber 2009-06-23 00:48:36 UTC

Works for me... I never even get this span in my output, can you clarify?

Comment 2 Raphael Champeimont 2009-06-23 11:05:47 UTC

Well, you can look at that page on my wiki, which consists only of the wiki code <math>\int_A</math>:

Comment 3 Alexandre Emsenhuber [IAlex] 2009-08-26 20:02:41 UTC

The problem is not that the span is not closed, but that there is a <p></p> arround it. See the complete source:
<p><span class="texhtml">
</p>
<table>
		<tr style='text-align: center;'><td><span style='font-size: x-large; font-family: serif;'>&int;</span></td></tr>
		<tr style='text-align: center; vertical-align: top;'><td><i>A</i></td></tr>
</table>
<p></span>
</p>

Could reproduce locally if tidy is disabled.

Comment 4 Raphael Champeimont 2009-08-26 21:31:35 UTC

Ok. So is it not a bug because I should use tidy if I want XHTML or is it still a bug because it should nevertheless produce correct XHTML?

Comment 5 Alexandre Emsenhuber [IAlex] 2009-08-27 06:33:00 UTC

This is a bug because it should produce correct XHTML. :)
