[xsl] 'xsl:variable' as dynamic select for 'xsl:for-each'...

[Ollie Lord <ol@xxxxxxx>]

Hi all,

I'm having problems creating an xsl:variable that I can use as the node set 
for an 'xsl:for-each' tag.

Basiacally...
    <xsl:variable name="selectclause" select=" some nodes "/>
    <xsl:for-each select="$selectclause">
       ... my code...
    </xsl:for-each>


My problem is that the select statement of the variable needs to be 
dynamic. Such as... (and I know this doesn't work.. )

  <xsl:choose>
    <xsl:when test="$clientid = ''">
       <xsl:variable name="selectclause" select = "//client"/>
    </xsl:when>
    <xsl:otherwise>
      <xsl:variable name="selectclause" select = "//client[$clientid]"/>
    </xsl:otherwise>
  </xsl:choose>

  <xsl:for-each select="$selectclause">
	my code
  </xsl:for-each>

It doesn't work because the contents of the variable 'selectclause' cannot 
be changed.


Of course, this doesn't work either...

    <xsl:variable name="selectclause">
      <xsl:choose>
        <xsl:when test="$clientid = ''">"//client"</xsl:when>
        <xsl:otherwise>"//client[$clientid]"</xsl:otherwise>
      </xsl:choose>
    </xsl:variable>

  <xsl:for-each select="$selectclause">
	my code
  </xsl:for-each>


... because the content of $selectclause isn't a node set.

Does anyone have any advice for me?? Any help would be very much appreciated.

Thanks,
Ollie Lord.
