Re: Loading an external file of index

Jeni,

I've tried your sample using xalan and it complains.

The code is :

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="1.0">
        <xsl:variable 
name="sharedDoc">document('../shared/shared.xml')</xsl:variable>
        <xsl:key name="mysetofkeys" match="KEYBASE/KEY" use="@NAME"/>

        ....

    <xsl:template match="KEYREF">
        <xsl:variable name="keyrefname" select="@LINKEND" />
        <xsl:for-each select="$sharedDoc">
                <b><xsl:value-of select="key('mysetofkeys', 
$keyrefname)/ACRONYM" /></b>
        </xsl:for-each>
    </xsl:template>

        ...

</xsl:stylesheet>


And the error is, at runtime transformation :

=============================
Transforming...
XPATH: Can not convert #UNKNOWN to a NodeList!
Xalan: was not successful.
XSLProcessor: done

Any idea ?

Regards,

Pierre
