“Tabs” section of Visio (see attached file) ‘page1.xml’ file is transformed into a self-closed tag after the file is processed using the libraries.
Code used:
// Load diagram
Diagram diagram = new Diagram(dataDir + "Tabs_normal.vsdx");
// Save diagram
diagram.Save(dataDir + "Tabs_normal_Target.vsdx", SaveFileFormat.VSDX);
What you will see in target file is that the changes from tag pair into self closed XML element and as such basically removed the feature.
