Filtering a specific string

[Sue]

I'm comparing a large source file base and there is a commented string at the top of each file that has to do with a source code branch change. In many cases, this is the only change in the file, but I'd like to ignore the change in the file comparisons. The first file looks something like:
* $URL: http://subversion.test.com/core/src/model

and the second file looks something like:
* $URL: http://subversion.test.com/newbranch/src/model

Is there some way to let ExamDiff pro know to ignore that line in both files so that ONLY other changes in the file shows up in the diff? Suggestions (and/or) samples of how to do this would be appreciated.
