You have to use the variables feature of the current WD. Replace the second TR element in your attempted solution by the following: <TR> <xsl:variable name="cols" expr="Column"/> <xsl:for-each select="../../Columns/Column"> <TD> <xsl:variable name="colname" expr="@name"/> <xsl:value-of select="$cols[@name=$colname]"/> </TD> </xsl:for-each> </TR> Roger Costello wrote: > > Hi Folks, > > Are you up for a mind-bending XSL problem?
