HTML Support

HTML Tags

The WbHtmlView attempts to ignore mismatched or missing Tags. It can parse any HTML, no matter how badly messed up the Tags are, although it might do a pretty bad job of rendering the results. It does simplistically attempt to repair missing </p>, but other problems are solved by ignoring Tags. Warnings will appear on the command line showing its best guess as to what the problem was. Valid tags include:

  • a - anchor Ex:<a href="#fragment">Title</a> and <a name="fragment">Title</a> (Attributes href and name)
