Re: [igraph] Problem loading Graphml file with edge weights in igraph

The <data> keys should be _inside_ the corresponding <edge> tags and  
not after them. igraph is pretty conservative in GraphML parsing, so  
it refuses to load any GraphML file that does not adhere to the  
GraphML standard (although it definitely shouldn't crash, I'll check  
that later).

So the proper syntax is:

<edge source="2" target="3">
  <data key="d1">17.19</data>
</edge>
