RE: [xsl] Connecting the Source and Destination fields

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

Hi All,
Christoph, Thanks for the reply .. 
After having a look at past posts regarding micro-pipelining...
If I am not wrong, by applying micro-pipelining technique we are trying to
get an output which in turn is processed to get the actual output.
Please correct if I am wrong. I think I am not !

I think even after sorting my input (using micro-pipelining) I will not be
able to get the desired output.

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.2/event.7" source="block.2/event.6"/> 
<connection destination="block.2/event.8" source="block.2/event.7"/>

<connection destination="block.2" source="block.0"/>
<connection destination="block.1" source="block.2"/>


I am expecting
block.0 -> block.2 -> block.1
 
i.e. where each block is replaced with the connections of events in that
block .. I get 

---------------------

(block.0/event.0 -> block.0/event.1 - > block.0/event.2)  
-> 
(block.2/event.6 -> block.2/event.7 - > block.2/event.8)             
->
(block.1/event.3 -> block.1/event.4 - > block.1/event.5)

---------------------
This is what exactly I am expecting 


Thanks
Yaswanth

This seems to be a use-case for the in another thread mentioned so-called 
"micro-pipelining". First process the input data to make them fit your 
needs, then do whatever you want with the cleaned up data. 

Hope I got it right this time...

Greetings Christoph
