When running my program (graphml.cpp/hpp), I get:
./batch-c-delaunay-10000: line 7: 2801 Abgebrochen ./separator -i /algodaten/separator/graphs/large/c-delaunay.graphml -f /algodaten/separator/graphs/large/output/c-delaunay-dj-noopt.csv --best-fundamental-cycle -p -d TRACE - main() entered TRACE - command line parsed TRACE - options analysed and stored terminate called after throwing an instance of 'boost::parse_error' what(): parse error: on line 6680, column 1: invalid value "

From the file:

From the program:
node_mapstd::string label_map(g); // throw-away stuff ... dynamic_properties dp; ... dp.property("label", make_leda_node_property_map(label_map)); ... read_graphml(in, g, dp);
Why does the GraphML reader try to parse the d0 (label) attribute as a double?!
Thanks a lot!

It seems to me not that it is trying to parse the label as a double, but that the label value is invalid, i.e. empty. Could you send the whole file (preferebly) or at least the line (6680) where the error happens, so that I can take a closer look?
Thanks, Tiago

According to the file you sent my by private mail, around line 6680 there is the following (white space and newlines omitted):
<data key="d4"></data>
And 'd4' is the key for a property of type double named 'label' (hence the confusing error message). Such an empty entry cannot be converted to a double value, so indeed the file is invalid...
Cheers, Tiago

OK, thanks a lot.
I renamed the property to label2 to avoid confusion. Is it possible to have attributes with the same name for nodes and edges?
And maybe the error message should mention for which kind of graph element the attribute is ...
Cheers,
Jens

Yes, it should be possible.

Yes that would be clearer. I'll see if I get around to it. (of course, patches are always welcome :-)

Yes, it should be possible.
And the dynamic_properties object distinguishes them with some tag, right?

It distinguishes them with the key type (vertex or edge descriptor, or a graph_property tag).
