What version are you using? Unfortunately, the versions currently distributed with Boost (that's Spirit V2) is more like a beta as it has some bugs and isn't feature complete (that's why we didn't put it in the front row, keeping Spirit.Classic as the main version to use). OTOH, the code in Boost SVN trunk (that's V2.1) is really very stable and has matured a lot. If you want to experiment with Karma this is definitely the version to use. The expressions described by OvermindDL1 should work, so I suspect you're trying to make it working using the outdated code...

HTH
