My preference when I see poorly-designed XML like this is to start by writing a
transformation that turns it into well-designed XML, in this case converting
<Level_1_Amt>100</Level_1_Amt>
to
<Amt level="1">100</Amt>
The great advantage of this is that you only need to do it once; from then on
you can work with your easier-to-manipulate XML.

Hello all,
I have a data scenario like this (edited down for clarity) where I have
multiple tags that have the actual level number in the tag name:
<foo>
<Level>
<Level_No>1</Level_No>
</Level>
<Level>
<Level_No>2</Level_No>
</Level>
<Level>
<Level_No>3</Level_No>
</Level>
<Cost ID='1'>
<Level_1_Amt>100</Level_1_Amt>
<Level_2_Amt>200</Level_2_Amt>
<Level_3_Amt>300</Level_3_Amt>
</Cost>
<Cost ID='2'>
<Level_1_Amt>50</Level_1_Amt>
<Level_2_Amt>100</Level_2_Amt>
<Level_3_Amt>150</Level_3_Amt>
</Cost>
<Cost ID='3'>
<Level_1_Amt>175</Level_1_Amt>
</Cost>
<Cost ID='4'>
<Level_3_Amt>400</Level_3_Amt>
</Cost>
</foo>
I am trying to sum up the amounts in the following code, but am getting a
syntactical error about how I am trying to pass the parameter value into the
tag name:
<xsl:stylesheet version="2.0" xmlns="http://www.w3.org/1999/xhtml";
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:xs="http://www.w3.org/2001/XMLSchema";>
<xsl:output method="xml" indent="yes"/>
<xsl:template name="buildLevel">
<xsl:param name="levelNum"/>
<Level_Amt>
<xsl:value-of
select="sum(/Story/Level_{$levelNum}_Amt)"/>
</Level_Amt>
</xsl:template>
<xsl:template match="Cost">
<xsl:for-each select="/foo/Level">
<Level>
<xsl:call-template name="buildLevel">
<xsl:with-param name="levelNum"
select="Level_No"/>
</xsl:call-template>
</Level>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
Is there a way I can do something like this? I am trying to avoid explicitly
calling each tag by name since there could be up to 9 levels in the data and
there are multiple tags that have the level number in them. Thank you in
advance.
