RE: [xsl] Passing a Map as parameter to XSLT.

["DEVAL SHAH" <devals9@xxxxxxxxxxx>]

Hello,
Thank you for the reply.

I am still not able to access the parameter that I pass to XSLT.

Let me explain what I want to do.

I want to pass in key,value pairs to XSLT. I hava a Map object in Java which 
contains this key value pair. I read in some forum that there is no direct 
way to pass this object as a Map so I need to convert it into xml format. So 
I am converting it into a xml format and setting it as the parameter. I am 
using javax.xml.transform.Transformer. I set the parameter as:
transformer.setParameter("XSLTParameter",xmlDoc);
where xmlDoc is some org.w3c.dom.Document object.

Now in xsl I try to get this parameter using <xsl:param name="XSLTParameter" 
/>.
I want to loop through the xml document that I have passed in XSLTParameter 
using some key.
So I define
<xsl:key name="xsltParameterMap" match="/*/map/entry" use="@key"/>

I Tried to loop in following manner.

<xsl:for-each select="key('xsltParameterMap','line')">
.........
</xsl:for-each>

XSLT is not going inside this loop. I am sure I am setting 'line' as one of 
the key value in the XML that I am passing as parameter to the XSLT. So it 
should go inside the loop.

Any help on this ?

Thanks
Deval
