Looking forward to your advice

INPUT File

Please note the placement of parentheses. Adding or removing a pair of parentheses in the wrong place will cause errors.

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:key name="rowByB" match="row" use="concat(generate-id(preceding-sibling::row[A='Unit'][1] ), B)"/>
<xsl:template match="/*">
<xsl:copy>
<xsl:for-each select="row[A != 'Unit'][count(.|key('rowByB', concat(generate-id(preceding-sibling::row[A='Unit'][1]), B))[1] )= 1]">
<xsl:copy>
<xsl:copy-of select="A"/>
<xsl:copy-of select="B"/>
<xsl:variable name="AddSum">
<xsl:value-of select="preceding-sibling::row[A='Unit'][1]/following-sibling::row[1]/B"/>
</xsl:variable>
<D>
<xsl:choose>
<xsl:when test="B = $AddSum">
<!-- add Unit value -->
<xsl:value-of select="sum(key('rowByB', concat(generate-id(preceding-sibling::row[A='Unit'][1]), B))/D) + preceding-sibling::row[A='Unit'][1]/D"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="sum(key('rowByB', concat(generate-id(preceding-sibling::row[A='Unit'][1]), B))/D)"/>
</xsl:otherwise>
</xsl:choose>
</D>
</xsl:copy>
</xsl:for-each>

Hi James,

I have taken your advice and have gotten to a certain point where i seem to be hitting a wall.

Im attaching a sample of the input file and the XSLT which i have editted so far.

I need the conversion to only sum up the <royalty>, <amount>, <fee> etc elements of the following elements of rows which preceding <type> elements are named RELEASE and have the same <releaseid> and <order> number of the RELEASE rows <order> number. Otherwise i need the data just the way it is displaying a single TRACKS's row. Also, for the row which has been consolidated for a RELEASE, i need its type to be named RELEASE aswell to identify it. Im not sure how to get the when/otherwise coding to do this..


Looking fowrard to your feedback and thank you extremely much for your help,

Mike
