I needed to find the total purchase order amount given the quantity and line item price on an X12 850 using XSLT and .NET to transform XML into HTML.
In my case:
PO102 = Quantity
PO104 = Price
Add the following to the stylesheet declaration:
xmlns:msxsl=”urn:schemas-microsoft-com:xslt”
for example:
<xsl:stylesheet version=”1.0″ xmlns:xsl=”http://www.w3.org/1999/XSL/Transform” xmlns:ns0=”http://schemas.microsoft.com/BizTalk/EDI/X12/2006″ xmlns:msxsl=”urn:schemas-microsoft-com:xslt” xmlns:var=”http://schemas.microsoft.com/BizTalk/2003/var” exclude-result-prefixes=”msxsl var userCSharp” xmlns:userCSharp=”http://schemas.microsoft.com/BizTalk/2003/userCSharp>”>
In your XSLT use the following code, modifying the referenced node and element within your XML
<xsl:variable name=”tmpTotal”>
<total_amount>
<xsl:for-each select=”ns0:PO1Loop1″>
<item>
<xsl:value-of select=”ns0:PO1/PO102 * ns0:PO1/PO104“/>
</item>
</xsl:for-each>
</total_amount>
</xsl:variable>
<total>
<!–<xsl:variable name=”myTotal” select=”msxsl:node-set($tmpTotal)”/>–>
<xsl:variable name=”myTotal” select=”$tmpTotal”/>
<xsl:value-of select=”sum(msxsl:node-set($myTotal)/total_amount/item)” />
</total>
