Regex Validation

[varunrap]

Hi,

I have an application in which I need to validate a word which might have multiple variation. For example, the word "trust". I need a regex validation to pull out variations like, trusty, tr-ust, tr ust, trustall. Could anyone suggest a regex pattern for this?

You cannot really use regex to validate against possibly hundreds of related words related to one word (you can also have trustee, trustiness, trustworthy, trustful, etc.)

Regex validation will however allow you to strip any non-alpha characters, so you can compare only the alpha characters of the word.

Therefore tr-ust, tr'ust, tr ust or t*r*u*s*t will always validate to trust.

static bool IsEquivalentString(string s1, string s2)
{ 
  return s1==Regex.Replace(s2,"[^a-zA-Z]","");
}

Hope this helps

Stripping out alphanumeric characters, is not an option. Unfortunately due to the configuration and setup of the application, I need something that will block the different varitions of the word.
