I am defining a DyanmicSyntaxLanguage.  I've got the bracket highlightting to work except that nested brackets aren't getting highlighted correctly.  For every opening bracket the first closing bracket gets highlighted.

For example:

((test) asdf )

 

How can I get the parser to match these correctly?

Hi Norbert,

I can't read your language definition since it's all on one line.  But anyhow, please take a look at what we did in the ActiproSoftware.Cpp.xml example.  That supports nesting fine.
