How do I not include the first part of a Text String in my Regex?

I am using the Text String cdblt31.funtimes.com and DO NOT want to include "cdbltl31" in my Regex. How do I not capture that part?

>Solution :

This pattern will match all except the part you don’t want.

\.\w+\.\w+$

• First is a point which we have to escape as \. because it has a special meaning in regex.
• Then \w matches any word character (basically letters and numbers).
• + means one or more times ie. any number of repeats (except 0).
• We then re-use the same symbols \.\w+ because we want to match a second point and more word characters.
• Finally $ means the end of the line.
  We could also write

(\.\w+){2}$

I’ll let you look up the new characters.
