lucky,
Do you want to replace a list of words with a single word, or replace a list
of words with an alternate list of words?

Did you look up RegEx.Replace in the online help?

http://msdn.microsoft.com/library/d...tregularexpressionsregexclassreplacetopic.asp

This topic provides a sample:
http://msdn.microsoft.com/library/d...RegularExpressionsRegexClassReplaceTopic1.asp

Here is an example of replacement patterns:

General information on Regular Expressions:
http://msdn.microsoft.com/library/d...s/cpguide/html/cpconcomregularexpressions.asp

For replacing a list with a list I normally use the overload that accepts a
MatchEvaluator. For replacing a list with a single word I normally use the
overload that accepts a single string. I have not used replacement patterns
yet...



Expresso & RegEx Workbench both have wizards of varying degrees to help you
build your expression, plus they allow you to test your expressions, also
the analyzer/interpreter in each is rather handy.
