Why can't you save this as a text file and search the text file? Any line breaks should come out properly in the text file. One purpose of RTF is to mark where line breaks are, among other things.

Comment on Re: How can I find a line in a RTF file?
A few lines (using Win::OLE or even a system call to whatever RTF-capable editor you have) to begin your processing with the "save as text" operation shouldn't add more than a trivial coding job, and should incur only a small time penalty.
