Re: [xsl] Get value from $Variable

[David Carlisle <davidc@xxxxxxxxx>]

whenever you have an idiom of the form

)/Languages/Language[@Language_Id=$Language_Id]

I think it's worth using a key, it might be quicker but whether it is or
isn't it makes the code a whole lot easier to read.


     <xsl:for-each select="Weekdays/Day">
          <xsl:variable name="Current_Id" select="@Id"/>
          <xsl:value-of select="$Language/Weekdays/Weekday[@Wd_Id =
$Current_Id]"/><xsl:if test="following-sibling::*[1]">, </xsl:if>
     </xsl:for-each>

could all be replaced by:

<xsl:value-of select="Weekdays/Day/key('k',@Id,$Language)" separator=", "/>


where the key is something like


<xsl:key name="k" match="Weekday" use="@Wd_Id"/>
