| Re: [sumo-user] Defining variables in .rou file? |
Hi,
actually you can use XML entities to do that:
<!DOCTYPE routes [
<!ENTITY speed "10">
]>
<routes xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:noNamespaceSchemaLocation="http://sumo.dlr.de/xsd/routes_file.xsd";>
<vehicle id="0" depart="0" departSpeed="&speed;">
<route edges="4/1to3/1 3/1to2/1 2/1to1/1 1/1to0/1"/>
</vehicle>
</routes>
This may work only as long as XML validation is enabled in SUMO (which
it is by default but it is sometimes disabled in the examples).
Best regards,
Michael
