Hi there,
I am using igraph in order to read, process and write graphml files of
graphml version 1.1 (http://graphml.graphdrawing.org/xmlns/1.1/graphml.xsd).
I get the graphml files from a java generator and postpress them with
the igraph python interface.
The problem is, that the java graphml generator creates specific
namespaces in the files, e.g.
"xmlns:ns2="http://www.w3.org/1999/xlink"; " such that it results in a
file that looks like follows:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<graphml xmlns:ns2="http://www.w3.org/1999/xlink";
xmlns:ns3="http://graphml.graphdrawing.org/xmlns";>
<ns3:graph id="Barabasi-Albert-73751112" edgedefault="undirected">
<ns3:node id="0"/>
<ns3:node id="1"/>
<ns3:node id="2"/>
<ns3:edge id="0" source="1" target="0"/>
<ns3:edge id="1" source="2" target="1"/>
</ns3:graph>
</graphml>
which is not readable by igraph anymore ("igraph._igraph.InternalError:
Error at foreign-graphml.c:1139: Graph index was too large, Invalid value").
I am currently using Debian Jessie with igraph 0.7.0 and Python 2.7.8.
You have any ideas on how to fix that without processing the file
through awk/sed?
Regards,
Robin
