Something along these lines would work

Subject: [xsl] reccursive sum ?
For each "ME" node in LIST.xml, i calculate the number of "devoirs". To do
so I must open each MATIERE.XML and making a count of all "DEVOIR" nodes.
LIST.xml looks like this :
<LISTE-ME>
<ME id="0010"/>
<ME id="0045"/>
<ME id="0152"/>
</LISTE-ME>
Each ME has a description in his own file, for instance the file 0010.xml
looks like this :
<ME ref="0010">
<FOURN label="anything">
<DEVOIR name="anything">
<DEVOIR name="anything">
</FOURN>
<FOURN label="anything">
<DEVOIR name="anything">
<DEVOIR name="anything">
<DEVOIR name="anything">
</FOURN>
</ME>
The XSL apply on LIST.xml looks like this :
<xsl:template match="LISTE-ME">
<xsl:for-each select="ME">
<xsl:variable name="ThisMEid">
<xsl:value-of select="@id"/>
</xsl:variable>
ME <xsl:value-of select="@id"/> :
<xsl:call-template name="NbreDevoirsME">
<xsl:with-param name="MEid" select="$ThisMEid"/>
</xsl:call-template>
devoirs <br/>
<xsl:for-each/>
</xsl:template>
<xsl:template name="NbreDevoirsME">
<xsl:param name="MEid"/>
<xsl:variable name="MEfile">
<xsl:value-of select="$MEid">.xml
</xsl:variable>
<xsl:value-of select="count(document($MEfile)/ME/FOURN/DEVOIR"/>
</xsl:template>
The Output would be here something like this :
ME 0010 : 5 devoirs
ME 0045 : 3 devoirs
ME 0152 : 7 devoirs
What i'd like is the total number of devoirs for all ME. ==> TOTAL = 15
devoirs
At this point I do not manage anymore :
* I m pretty sure the solution must be a reccursive template, but i did
not
find it ...
* I thought about a way to calculate this sum :
if I write <xsl:value-of select="5+3+7">, it gives 15.
So I put in a variable "string" the expression to be calculated :
<xsl:variable name="String">
<xsl:for-each select="ME">
<xsl:variable name="ThisMEid">
<xsl:value-of select="@id"/>
</xsl:variable>
<xsl:call-template name="NbreDevoirsME">
<xsl:with-param name="MEid" select="$ThisMEid"/>
</xsl:call-template>
<xsl:if test="position()!=last()">
+
</xsl:if>
</xsl:for-each>
</xsl:variable>
Off course, when I write <xsl:value-of select="$String"/> the processor
don't calculate it, it just dysplay the string.
Is there a way to tell him, $string must be interpreted as a Xpath
expression which you must calculate ?
