Re: [xsl] Yet Another Entity Ref question!

[Marco Guazzone <sguazt@xxxxxxxxxxx>]

Thanks Mike!!
However the problem is more general; suppose you have a content management
engine that takes as input an XML, applies an XSL and produces an HTML.
So an unknown user write an XML sheet (following a well-known grammar);
inside this sheet he/she can put an element like
     <entity>ent</entity>
where "ent" can be numberi (e.g. "#x0A") or symbolic (e.g. "agrave").
The engine should transform this element into the entity reference "&ent;"
(e.g. "&#x0A;" or "&agrave;"), through an XSL template like:

<xsl:template match="entity">
  <xsl:text
disable-output-escaping="yes"><![CDATA[&]]></xsl:text><xsl:value-of
select="." /><xsl:text>;</xsl:text>
</xsl:template>

the problem arises when I use the result of this template; if the result
is taken as-is, I will get the right thing ("&ent;"); if the result is
stored inside a variable I have to disable-output-escaping when using
xsl:value-of. For example

XML
...
<doc>
  <label>Foobar<entity>ent</entity></label>
</doc>

XSL:
...
<xsl:template match="doc">
   <xsl:apply-templates select="label" /> <!-- ok! -->
   <xsl:variable name="label">
      <xsl:apply-templates select="label" />
   </xsl:variable>
   <xsl:value-of select="$label" />  <!-- not ok -->
   <xsl:value-of disable-output-escaping="yes" select="$label" />  <!-- ok
-->
</xsl:template>
...

So I can't substitute the value of the entity with the related UNICODE
representation because I don't know that entity.
Any idea?
Thanks so much!!
