Re: [sumo-user] Programmatic Access to NETEDIT
To change a node position you can create a patch file like this:
<nodes>
  <node id="myNodeID" x="newX" y="newY"/>
<nodes>
netconvert -s old.net.xml -n patch.nod.xml -o patched.net.xml

This can be done in ~4 lines of python so you won't get a big advantage from using sumolib.xml.parse.


Unfortunately, we never got around to documenting all sumolib functionality.
SUMO documentation tends to grow via user questions so feel free to ask about specific functions.

Jakob

Hello,

  Thank you for for the prompt reply.
  I have searched into sumolib.xml.parse but I can't see how I can use 
it as I can't find any documentation. I have also tried sumolib but I 
can not see how I can change a node's position.

Thank you,
Tom
