Gephi XML parser fails when encountering U+0001 #1164
Description
Related to MyWebIntelligence/MyWebIntelligence#216 (comment)
This issue was found in Gephi 0.8. I haven't tried on Gephi 0.9.
Try importing the following GEXF document in Gephi :
<?xml version="1.0" encoding="UTF-8"?>
<gexf xmlns="http://www.gexf.net/1.2draft" version="1.2">
<graph mode="static" defaultedgetype="directed">
<attributes class="node">
<attribute id="domain_title" title="domain_title" type="string"/>
</attributes>
<attributes class="edge">
<attribute id="weight" title="weight" type="integer"/>
</attributes>
<nodes>
<node id="n1" label="n1">
<attvalues>
<attvalue for="domain_title" value="�a"/>
<attvalues>
</node>
</nodes>
<edges>
</edges>
</graph>
</gexf>
Note the funky character as attribute value, it's U+0001 (and this is where the XML parser trips).
This character is forbidden in XML 1.0 documents, but allowed in XML 1.1 documents. See https://en.wikipedia.org/wiki/Valid_characters_in_XML
