Subject Re: [StrSubstitutor] Can StrSubstitutor be used without a prefix or suffix?
Date Mon, 10 Sep 2007 21:27:30 GMT
To be clear, I meant that I wrote my own search & replace code, not 
using StrSubstitutor.

Even if it were possible to do something with StrMatcher, as a future 
enhancement, it might be nice if it could also be done by setting the 
prefix and suffix to "" directly from the StrSubstitutor API.
