XSL transformation question

[psynergy]

Hello!

I have the following document structure

<Items>
<Item>
<Type>foo</Type>
<Value>1.00</Value>
</Item>
<Item>
<Type>bar</Type>
<Value>-2.00</Value>
</Item>
<Item>
<Type>foo</Type>
<Value>1.00</Value>
</Item>
<!-- more <Item>s here -->
</Items>

To summarize, <Items> can contain any number of <Item>
tags. Each <Item> tag contains <Type> and <Value> tags.

What I need to do is the following. Given value of &quot;foo&quot;,
I need to find all <Item> tags with <Type> set to &quot;foo&quot;
and print out the sum of all <Value>s.

Is this something that can be done? I can't figure this
out for the life of me... heh

Thanks!

The simplest approach will be to use the style sheet below:
_________________________________________________________

<xsl:stylesheet xmlns:xsl=&quot;

http://www.w3.org/1999/XSL/Transform&quot;

version=&quot;1.0&quot;>
<xslutput method=&quot;html&quot; version=&quot;4.0&quot; />
<xsl:template match=&quot;/&quot;>
<xsl:apply-templates />
</xsl:template>
<xsl:template match=&quot;Items&quot;>
<p>
<xsl:apply-templates />
</p>
</xsl:template>
<xsl:template match=&quot;Item&quot;>
<xsl:variable name=&quot;type&quot; select=&quot;Type&quot; />
<xsl:number format=&quot;1. &quot; />
<xsl:value-of select=&quot;$type&quot; />
<xsl:value-of select=&quot;' sum = '&quot; />
<xsl:value-of select=&quot;sum(/Items/Item/Value[../Type=$type])&quot; />
<br />
</xsl:template>
</xsl:stylesheet>
