[xsl] Connecting the Source and Destination fields

["Yaswanth" <yaswanth.mtrx@xxxxxxxxx>]

Hi All,

I am trying to arrange the chain of event connections by mapping the Source
and Destination of each Connection.

When my XML file is something like this:

<connection destination="event.1" source="event.0"/>
<connection destination="event.2" source="event.1"/>
<connection destination="event.3" source="event.2"/>
<connection destination="event.4" source="event.3"/>

// Ordered
// Please note that The Destination Value of any node is equal to the Source
value of the next Node
           
Here I am taking the 'source' value from the first 'connection' and by keep
on appending the 'destination' value of all the 'connection's I get the
Output as:


event.0 -> event.1 -> event.2 -> event.3 -> event.4

Problem:

Now my XML input file is changed to some thing like this :

<connection destination="event.1"  source="event.0"/>                
<connection destination="event.3"  source="event.2"/>
<connection destination="event.2"  source="event.1"/>
<connection destination="event.4"  source="event.3"/>

// Unordered
// Please note that The Destination Value of any node is not always equal to
the Source value of the next Node
           
If I process this XML file in the same way I did the earlier one I will get
output as:

event.0 -> event.1 -> event.3 -> event.2 -> event.4

Here event.1s destination is event.2 only but in the Output I am having
event.3 as the destination.
event.2's destination is event.3 only but in the Output I am having event.4
as the destination.
event.3's destination is event.4 only but in the Output I am having event.2
as the destination.

I know this is happening because of the Logic I used in arranging these
things..

Can I get some push on how to arrange these things in Order?!
