[xslt] Still issues with functions

[Nikolai Weibull <now disu se>]

Hi!

The following

<xsl:stylesheet version="1.0"
               xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
               xmlns:func="http://exslt.org/functions";
               xmlns:a="a"
               extension-element-prefixes="func">
 <xsl:output method="text" encoding="UTF-8"/>

 <func:function name="a:a">
   <func:result>
     <xsl:apply-templates mode="a"/>
   </func:result>
 </func:function>

 <xsl:template mode="a" match="node()">
   <xsl:text>a</xsl:text>
 </xsl:template>

 <xsl:template match="/">
   <xsl:variable name="a" select="a:a()"/>
   <xsl:value-of select="$a"/>
   <xsl:text>,</xsl:text>
   <xsl:value-of select="$a"/>
   <xsl:text>&#x0a;</xsl:text>
 </xsl:template>
</xsl:stylesheet>

with

<a/>

as input outputs only

a,

One would expect it to output

a,a

That’ll only happen if we replace the definition of “a” with 
“string(a:a())”.

I have no suggestion as to why this is happening, but I assume it 
has something to do with the latest modifications of the handling 
of functions and result trees fragments and such.

This was tested with the latest sources from the Git repository.
