I am looking for a regex string (to use in GA) that identifys entries that start with words in full capitals.

For example to include:

but exclude:

I have tried to use: ^[A-Z]{5,25}

Any ideas?

To match a string that starts with an upper-case word, use:

^[A-Z]+\b.*

If you want to exclude particular upper-case words at the start of the string, for instance TOM and JERRY, modify it to:

^(?!(?:TOM|JERRY)\b)[A-Z]+\b.*

Explanation

  • The ^ anchor asserts that we are at the beginning of the string
  • [A-Z]+ matches upper-case letters
  • \b is a word boundary that matches a position where one side is a letter, and the other side is not a letter (for instance a space character, or the beginning of the string)
  • .* matches any chars to the end of the string

For the second one, (?!(?:TOM|JERRY)\b) is a negative lookahead that asserts that what follows is not TOM or JERRY, followed by a boundary.
