Re: [xsl] Selecting templates by root elements from input (sub-) docs

[Joerg Heinicke <joerg.heinicke@xxxxxx>]

Hello Yves,

if you write

<xsl:apply-templates select="document($my_subdoc)/*"/>

a template is searched matching on the root element of the subdoc, which 
should be <chapter/> or <section/>.

In these (both (?)) templates you need to declare the parameter:

<xsl:template match="chapter">
    <xsl:param name="my_subdoc" select="'default value'"/>
    <xsl:value-of select="$my_subdoc"/>
</xsl:template>

The <xsl:value-of/> should output the value of the param now. If not, 
you must post a bit more out of your XSLT.

Regards,

Joerg
