Why is hit false? I'm trying to find any Name XML field that has an 's' in the name. I don't understand what could be wrong.

Thanks!

You are using . in a character class, where it means literally ., I think you mean to use in the sense of any character - so .* rather than [.]*

string regex = "<Name(.|\\s)*>.*s.*</Name>";

With XPath, this could be as easy as /Name[contains(.,'s')]
