I really appreciate you explaining this in English for me.  You have
been a big help. 

Thanks,

Kenny Akridge

Sure, I can try to explain it.

Essentially it's a grouping problem (see
http://www.jenitennison.com/xslt/grouping/muenchian.html). In your case
you want to bring together all of the AccountLineItem nodes that have
the same value for GLAccountNumber. Your summation is correct, we just
grab each unique AccountLineItem/GLAccountNumber we encounter and the
inner loop collects all the AccountLineItem nodes that match the
GLAccountNumber. I may have never come up with this method on my own
either, but that's why I read this list, it's a good place to learn new
techniques. :)

Breaking down the selection:
select="AccountLineItem[GLAccountNumber[not(. =
preceding::GLAccountNumber)]]

In English: 
Select all AccountLineItem nodes which have a child GLAccountNumber node
that is not equal to any preceding GLAccountNumber nodes.

The preceding:: axis here would also grab GLAccountNumber nodes that are
outside of AccountLIneItem nodes. In your case this doesn't matter, but
to be more specific I probably should have written
preceding::AccountLineItem/GLAccountNumber.

While writing this I noticed that you don't need to select the
AccountLineItem nodes in the outer loop, but just the GLAccountNumber
nodes. That would change the select statement to:

select="AccountLineItem/GLAccountNumber[not(. =
preceding::AccountLineItem/GLAccountNumber)]"

In English:
select GLAccountNumber nodes that are children of AccountLineItem nodes,
and are not equal to any preceding GLAccountNumber nodes that are
children of AccountLineItem nodes.

The references to GLAccountNumber in the loop would change to
self::node() or . (dot). Changing the select statement isn't critical,
but it might make it easier to follow what is being used.

Enjoy,
Josh

Josh, it seems like this code loops over the first node of every
different GLAccountNumber.  Then, it looks like an inner loop of all
nodes that match the node held in the outer loop.  Is this correct?  I
would have never thought of this.  I don't even really understand how it
works.

Can you explain this for me:

<xsl:for-each select="AccountLineItem[GLAccountNumber[not(. =
preceding::GLAccountNumber)]]">

Thanks.

Your problem is here:
<xsl:if test="not(GLAccountNumber = following::GLAccountNumber)">

following::GLAccountNumber is returning the next GLAccountNumber in
document order, not in the order that the for-each is iterating over the
elements.

One solution would be to group the AccountLineItem elements together by
GLAccountNumber and then output the subtotal after processing each
GLAccountNumber. 

<xsl:key name="account-by-number"
match="/ArrayOfAccountLineItem/AccountLineItem" use="GLAccountNumber"/>

<xsl:template match="ArrayOfAccountLineItem">

	<!-- iterate over distinct account numbers -->
	<xsl:for-each select="AccountLineItem[GLAccountNumber[not(. =
preceding::GLAccountNumber)]]">
		<xsl:sort select="GLAccountNumber" data-type="text"
order="ascending"/>
		<!-- iterate over all matching account numbers -->
		<xsl:for-each select="key('account-by-number',
GLAccountNumber)">
			<xsl:sort select="substring(SettleDate,1,10)"
data-type="text" order="ascending"/>
			<xsl:sort select="LineItemID" data-type="number"
order="ascending"/>

			<xsl:apply-templates select="."/>

		</xsl:for-each>

		<!-- Summary line, used to be in xsl:if in the
AccountLineItem template-->
		<tr>
			<td colspan="11">
				&#xA0;

		</tr>
		<tr>
			<td colspan="4">

			<td colspan="2" class="fieldName"

		</tr>
