Hi Ronan,
Thanks for the explanation.
Now it?s clear regarding that expression.
I am facing problem
For the below input
<connection destination="block.0/event.1" source="block.0/event.0"/>
<connection destination="block.0/event.2" source="block.0/event.1"/>
<connection destination="block.1/event.4" source="block.1/event.3"/>
<connection destination="block.1/event.5" source="block.1/event.4"/>
<connection destination="block.1" source="block.0"/>
For now I get output as
Line 1 : block.0/event.0 -> block.0/event.1 - > block.0/event.2
Line 2 : block.1/event.3 -> block.1/event.4 - > block.1/event.5
Line 3 : block.0 -> block.1
-------------------
Here in line 3 how can I get (Line:1) -> (Line:2)
i.e.
(block.0/event.0 -> block.0/event.1 - > block.0/event.2)
->
(block.1/event.3 -> block.1/event.4 - > block.1/event.5)
block.0 -> block.1 means
All events in block.0 followed by all events in block.1
--------------------
I tried this but I am unable to get.
Can you or any one please help in doing this ?
Please help !
Thanks,
Yaswanth

Hi can you please explain me what exactly the below line is doing and how
it
is working?
<xsl:for-each
select="/root/connection[not(/root/connection/@destination = @source)]">
First, some facts:
* If a connection has a destination that does not equal the source of
any other connection, then it is and the end of the chain.
* If a connection has a source that does not equal any other
connection's destination, then it is the start of the chain.
/root/connection[not(/root/connection/@destination = @source)]
This line is designed to select all the nodes that represent the start
of a chain. It does this by expressing the above statement in XPath:
"If a connection has a source that does not equal any other connection's
destination, then it is the start of the chain."
So, we want to select connections:
/root/connection
with a source attribute:
/root/connection[(_at_)source]
that does not equal any connection's destination:
/root/connection[not(/root/connection/@destination = @source)]
I hope this explains it...
