Re: [igraph] node data not being recognized

[Gabor Csardi]

Matthew,

I've just checked http://graphml.graphdrawing.org/specification.html,
you cannot have <key> inside of <graph>. Ie. your file should be something 
like:

<?xml version="1.0" encoding="UTF-8"?>
<!--  An excerpt of an egocentric social network  -->
<graphml xmlns="http://graphml.graphdrawing.org/xmlns";>

<!-- data schema -->
<key id="name" for="node" attr.name="name" attr.type="string"/>
<key id="gender" for="node" attr.name="gender" attr.type="string"/>

<graph edgedefault="undirected">
<!-- nodes -->
<node id="1">
 <data key="name">Jeff</data>
 <data key="gender">M</data>
 </node>
<node id="2">
 <data key="name">Ed</data>
 <data key="gender">M</data>
</node>
</graph>
</graphml>

Ps. it's ok if you don't join the list, but please consider that
i need to acknowledge your emails "by hand" and this might cause
delays, plus you might miss some of the answers.
