The DOT parser for label= strings does not seem to be properly handling: 1) backslash escaping 2) multiple values using | separator 3) nested values using { } See the "project" node label value in the attached file, and view the file in ZGRViewer to see what's expected.
Created attachment 189349 [details] Illustrates problem.
There are actually two different issues here: The first is escaping in quoted strings. This part is fixed with bug 337639 according to the DOT language spec (http://www.graphviz.org/doc/info/lang.html, in particular the footnote at the bottom): surrounding quotes are removed, and escaped quotes are converted to plain quotes (see TestGraphInstanceDotImport#escapedQuotes). The second is support for the special record syntax (http://www.graphviz.org/doc/info/shapes.html#record). Supporting that involves both extending the grammar and creating custom figures (contributions welcome, see also bug 321775).
Support for record-based shapes is handled in bug #454629 and support for html-like labels is addressed in bug #321775. As the initially reported parsing issues have been resolved, closing this as fixed.
