Perhaps you can post a real (or baudlerized sample) snippet of your actual data. It's amazing what a bit of exposure to regular expressions can help one spot, and here, you'll have many such well-educated eyes looking for proxy-para-markers.

I'm actually surprised -- no, very surprised -- that this request hasn't been posted higher in the thread.
