Re: Xsl:variable content should be empty

<snip />

<xsl:variable name="link" select="file_link"> </xsl:variable>

<snip />

As you can see, I am trying to construct an html link from the filename
and path held in the <file_link> element.

This works fine when I call the stylesheet in-line or from Javascript in
Internet Explorer, but when I run it with the PHP XSL extension, it
generates a warning: Xsl:variable content should be empty since select
is present. It's only a warning and the output is still as expected, but
clearly I'm doing something wrong.

>From reading up it seems to me this IS an xslt issue rather than a PHP
one. I just don't understand it.

<!-- with select -->
<xsl:variable name="x" select="file_link" />

<!-- with sequence constructor -->
<xsl:variable name="x"><xsl:value-of select="file_link" /></xsl:variable>

<!-- or more complex, like this: -->
<xsl:variable name="x">
   <xsl:for-each select="bla">
      <xsl:call-template name="xyz" />
      <xsl:apply-templates select="." />
   </xsl:for-each>
</xsl:variable>
