How I can get an ancestor ....

[Éric Riblair <eriblair@xxxxxxxxxxxx>]

HI,

In my work, I want to have an attribute value of an ancestor of a node ...

There is the context:

I built a list of HREF with the disorders to pass 2 arguments to an asp
file ... but I can't get the ID of the plant

...<xsl:for-each select="disorders/SgDisorderType" order-by="@IDENTIFIER">
            <DIV STYLE="margin-left:26pt; margin-right:1pt; font-size:10pt; 
	     font-weight:bold; padding-top:0pt;">
           <A TARGET="description">
           <xsl:attribute name="HREF" >
              disorder.asp?disorder=<xsl:value-of select="@IDENTIFIER" />
	&amp;plant=<xsl:value-of select="ancestor(SgPlantType[@ID])"/> 
           </xsl:attribute> 
           <xsl:value-of select="@NAME"/>
           </A>
           </DIV>
</xsl:for-each> ... 

The result of this is: ...disorder.asp?disorder=doryphore&plant=solanacées
And the XML look like this:

<SgPlantType CLASS="SgPlantType" NAME="tomate, aubergine et poivron"
ID="tomate,_aubergine_et_poivron">    
        <description></description>
        <categories>    
            <category>solanac&#233;es</category>
        </categories>
        <disorders MANAGER="DisorderTypes">    
            <SgDisorderType NAME="doryphore"
IDENTIFIER="doryphore"></SgDisorderType>
            <SgDisorderType NAME="anthracnose"
IDENTIFIER="anthracnose"></SgDisorderType>
            <SgDisorderType NAME="mildiou"
IDENTIFIER="mildiou"></SgDisorderType>
            <SgDisorderType NAME="br&#251;lure alternarienne"
IDENTIFIER="brulure_alternarienne"></SgDisorderType>
            <SgDisorderType NAME="septoriose"
IDENTIFIER="septoriose"></SgDisorderType>
</SgPlantType>

Thanks for any help,
Eric
