Re^4: Need help with a nested IF statement

That worked very well. Can you tell me what \b is looking for when you write "/\bnet"? What is considered a Word boundry? Also your split line, what is it doing logic-wise. I am pretty new to Perl and Regex still confuses me slightly. Thanks.

Can you tell me what \b is looking for when you write "/\bnet"? To prevent it from matching "foonet" What is considered a Word boundry? Between a `\W` and a `\w`, between a `\w` and a `\W`, between the start of string and a `\w`, and between a `\w` and the end of string. As a regex pattern: `/(?<=\w)(?!\w)\|(?<!\w)(?=\w)/` [download] Also your split line, what is it doing logic-wise. It splits between a `\n` and a `\w`.	[reply] [d/l] [select]

What is considered a Word boundry?

Between a \W and a \w,
between a \w and a \W,
between the start of string and a \w, and
between a \w and the end of string.

As a regex pattern:

/(?<=\w)(?!\w)|(?<!\w)(?=\w)/
