I want to add the Shipping Totals for each of the different orders (Message) into one total that I store in the Orders Table of my DB. I guess I need to use recursion, but nothing I have read on this is making any sense to me. It also does not help that they are using a <Component> tag then a <Type> to identify what each pricing item is. How do I return just the Shipping value, then add them up for a grand total?

(Better formated example available on request)

Also, while I'm at it. Is there a way to setup a sort of auto-increment number? I have used (xsl:value-of select="position()" />, but this is reset to 1 when the master node changes, and I would instead like to continue with the numbers in order.

[brucec]

You can accomplish it with Javascript in your XSLT or better yet, instead of using JS, you could try using a server side scripting language like ASP or PHP to increment the numbers and create the XML on the fly. Then use your xsl:value-of select to grab the value.

[schenz]

I do not care so much about the auto-increment stuff, I'll work around it.....

Here is the solution for the Adding of the Shipping Totals:
ok, this seems to be the solution:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<x#*$!put method="html" indent="yes"/>
<xsl:include href="Style1.xsl"/>

<xsl:template match="/">
<!-- Call the cosmetic formatting template -->
<xsl:call-template name="Style1"/>
<html><body>
<xsl:apply-templates/>
</body></html>
</xsl:template>

<xsl:template match="Envelope/Message">
<h1>Order Number: <xsl:value-of select="OrderReport/OrderID" /></h1>
Total Shipping: <xsl:value-of select="sum(OrderReport/Item/*/Component[Type='Shipping']/Amount)" />
</xsl:template>
