PHP :: Bug #49820 :: XSLTProcessor returns Error at xsl:variable with comment inside

[2009-10-09 13:03 UTC] felixsigl at gmail dot com

Description:
------------
I have a lot of XSL files which i want to process with the libxml XSLTProcessor. But the XSLTProcessor returns Error at xsl:variable with a comment inside. I don?t know exactly if this is a bug but i think so.

I know that i should use either a select attribute or child nodes in the variable to define the variable. but shouldn?t comments be ignored in that way?

Reproduce code:
---------------
the variable in the xsl file:

doesnt work!:
<xsl:variable select="1" name="var" >
   <!-- comment -->
</xsl:variable>

works:
<xsl:variable select="1" name="var" />

works too:
<xsl:variable name="var" >
   <!-- comment -->
</xsl:variable>

Expected result:
----------------
transformed XML

Actual result:
--------------
Error 1: compilation error: file file:///C:/Programme/xampp/test01.xsl line 4 element variable Line: 0 Column: 0 Error 1: XSLT-variable: The must be no child nodes, since the attribute 'select' was specified. Line: 0 Column: 0

Thank you for your bug report.

Can you also reproduce it if you remove the whitespace between the variable tags? In your example, the variable element would have a text child node with some whitespace in it. Technically, this is not allowed since the variable tag should have no content at all.

Hi, 

i have tried:

<xsl:variable select="1" name="var"><!--comment--></xsl:variable>

thus no whitspace

but the same error: XSLT-variable: The must be no child nodes, since the attribute 'select' was specified.

The second example without whitespace is a bug in libxslt. It's a pretty minor issue, but maybe I'll fix it in libxslt.

I had a deeper look at the XSLT spec and it seems the both cases are bugs in libxslt.

The following commit fixes this bug in libxslt
