Totalize nodes attibutes

[sgubert]

Hi,I have a little problem that I don't know how to resolve.I want to totalize some nodes. I'll give an example:

<CATEGORIES>	<CATEGORY ID="CAT1">		<ITEM VALUE="1"/>		<ITEM VALUE="1"/>		<ITEM VALUE="1"/>		<ITEM VALUE="1"/>	</CATEGORY>	<CATEGORY ID="CAT2">		<ITEM VALUE="2"/>		<ITEM VALUE="2"/>		<ITEM VALUE="2"/>		<ITEM VALUE="2"/>	</CATEGORY>	<CATEGORY ID="CAT3">		<ITEM VALUE="3"/>		<ITEM VALUE="3"/>		<ITEM VALUE="3"/>		<ITEM VALUE="3"/>	</CATEGORY><CATEGORIES>

I want to totalize the categories with ID CAT1, CAT2 e CAT3 separately. CAT1=4 CAT2=8 and CAT3=12.After, I would like to get the total sum of all Categories, for example, 24.I hope someone can help me,ThanksSamuel

Bar bones of a solution is as follows:

<xsl:template match="CATEGORIES">  <xsl:apply-templates/>  <xsl:value-of select="sum(CATEGORY/ITEM/@VALUE)"/></xsl:template><xsl:template match="CATEGORY">  <xsl:value-of select="sum(ITEM/@VALUE)"/></xsl:template>

Depending on the exact result format you want to add elements and text structuring the result.
