Hi I want to use some dot files generated for graphviz but I have some parsing issues. I am using HTML labels and it seems to cause problems. Here is my example: graph G { "1" [label=<foo<br/>bar>,shape=box, ]; "2" [shape=box, ]; "1" -- "2" [fontcolor="#FF0000", color="#FF0000", label="2.4e-04", ]; } This HTML label ("label=<foo<br/>bar>") causes this error: Traceback (most recent call last): File "community_graph_tool.py", line 47, in <module> main(sys.argv[1:]) File "community_graph_tool.py", line 30, in main g = load_graph(idotfile) File "/usr/lib/python2.7/dist-packages/graph_tool/__init__.py", line 1956, in load_graph g.load(file_name, fmt, ignore_vp, ignore_ep, ignore_gp) File "/usr/lib/python2.7/dist-packages/graph_tool/__init__.py", line 1712, in load ignore_ep, ignore_gp) RuntimeError: Wanted right bracket to end attribute list (token is "<identifier> 'bar'") If I remove <br/>, I get another error: Traceback (most recent call last): File "community_graph_tool.py", line 47, in <module> main(sys.argv[1:]) File "community_graph_tool.py", line 30, in main g = load_graph(idotfile) File "/usr/lib/python2.7/dist-packages/graph_tool/__init__.py", line 1956, in load_graph g.load(file_name, fmt, ignore_vp, ignore_ep, ignore_gp) File "/usr/lib/python2.7/dist-packages/graph_tool/__init__.py", line 1712, in load ignore_ep, ignore_gp) RuntimeError: Unclosed HTML string (at end of input) And if I completely remove the "label=<foo<br/>bar>,", it also removes all errors. Thanks for your work and time. Johan
