XSLT: Multiple conditional variable assignment

[obanite]

Hello,

Is there a better way of doing:

  <xsl:variable name="frlink">
  <xsl:choose>
  <xsl:when test="@isFriend = '0'"><xsl:value-of select="concat('friends.php?add=', @uid)"/></xsl:when>
  <xsl:otherwise> <xsl:value-of select="concat('friends.php?add=', @uid)"/></xsl:otherwise>
  </xsl:choose>
  </xsl:variable>
  <xsl:variable name="frstr">
  <xsl:choose>
  <xsl:when test="@isFriend = '0'"><xsl:value-of select="'FR_ADD_TO_FRIENDS'"/></xsl:when>
  <xsl:otherwise> <xsl:value-of select="'FR_REMOVE_FRIEND'"/></xsl:otherwise>
  </xsl:choose>
  </xsl:variable>

I.e. in an procedural language I would do:

if(a)
{
i = someval; j = someval; k = someval;
}
else
{
i = someotherval; j = someotherval; k = someotherval;
}

In XSLT it seems to be a case of put the conditional inside every single variable assignment - is there a better way?

Thanks,

Dave

There is another way, although this has it's own problems.

You could create a super variable

<xsl:variable name="super">
  <super>
    <xsl:choose>
      <xsl:when test="@isFriend = '0'">
        <frlink><xsl:value-of select="concat('friends.php?add=', @uid)"/></frlink>
        <frstr><xsl:value-of select="'FR_ADD_TO_FRIENDS'"/></frstr>
      </xsl:when>
      <xsl:otherwise>
        <frlink><xsl:value-of select="concat('friends.php?add=', @uid)"/></frlink>
        <frstr><xsl:value-of select="'FR_REMOVE_FRIEND'"/></frstr>
      </xsl:otherwise>
    </xsl:choose>
  </super>
</xsl:variable>
 

However, then $frlink beomes: $super//frlink
and $frstr becomes $super//frstr

If this causes errors due to result-tree-fragments, then you might need to use exsl:node-set($super//frlink) or msxsl:node-set($super//frlink)
