[xsl] Selecting node contents from several xml-files

[Jarkko.Moilanen@xxxxxx]

Hi!

Is there some possibility to select node values (numbers) from 
several xml -files and then count them all together? 

I did try to use 

<xsl:for-each select="$P1//P1Kurssi/P1Arvosanat">
//variable declared below
<xsl:for-each select="$P2//P2Kurssi/P2Arvosanat">
<xsl:value-of select="count(arvosana)"/>

<xsl:variable name="P1" select="document('P1.xml')"/>
<xsl:variable name="P2" select="document('P2.xml')"/>

example of xml -file:

<?xml version="1.0"  encoding="ISO-8859-1" standalone="yes"?>
<Document title="Keskiarvot kurssien arvosanoista">

<P1Kurssi koodi="P1" name=" P1 Johdatus vuorovaikutteiseen mediaan" 
link="http://hypst09.uta.fi:6969/cgi-bin/html?P1";>
        <Opiskelijoita>23</Opiskelijoita>
    	<P1Arvosanat>
		<arvosana>3</arvosana>
		<arvosana>2.25</arvosana>
		<arvosana>1.75</arvosana>
		<arvosana>1.25</arvosana>
		<arvosana>2.75</arvosana>
	</P1Arvosanat>
</P1Kurssi>
</Document>
