Hi,

I have a complex XSLT transformation and I am trying to figure out how to proceed with.
I am attempting to collect the information associated to a particular PortId. However this information is distributed across various elements as indicated below.
In the example below the information for port_id2 is across two <Map> elements. How would I extract the DOMAIN_ID associated to the same port_ids and transform them into the <ServicePort> element in the output xml.

Input.xml -

<AttributeList>
<Map>
<entry>
<key>PortId</key>
<value>port_id1</value>
</entry>
<entry>
<key>DOMAIN_ID</key>
<value>one</value>
</entry>
</Map>
<Map>
<entry>
<key>PortId</key>
<value>port_id2</value>
</entry>
<entry>
<key>DOMAIN_ID</key>
<value>13</value>
</entry>
</Map>
<Map>
<entry>
<key>PortId</key>
<value>port_id2</value>
</entry>
<entry>
<key>DOMAIN_ID</key>
<value>14</value>
</entry>
</Map>
</AttributeList>

Transformed.xml -

<?xml version="1.0"?>
<ServicePorts>
<ServicePort>
<PortId>port_id1</PortId>
<ServicePortDetails>
<VlanId>one</VlanId>
</ServicePortDetails>
</ServicePort>
<ServicePort>
<PortId>port_id2</PortId>
<ServicePortDetails>
<VlanId>13</VlanId>
</ServicePortDetails>
<ServicePortDetails>
<VlanId>14</VlanId>
</ServicePortDetails>
</ServicePort>
</ServicePorts>
<BandwidthSubscriptions>

Apologies for loosing the indentation but I couldn't get it right :(.
Thanks in advance.

Regards
Ananya

Hi Ananya,
this is a grouping problem; have a look at this web page that explain the various approaches at the problem: http://www.jenitennison.com/xslt/grouping/
