Subject Re: [StrSubstitutor] Can StrSubstitutor be used without a prefix or suffix?
Date Mon, 10 Sep 2007 20:38:08 GMT

Thanks for the advice. I had briefly looked at that and didn't see an 
obvious "match anything" StrMatcher so I opted to write my own code. 
Depending on formating, it's only around ten lines of code.
