Is There a Regular Expression to Pull all the Capital Letters out of a Phrase?

Updated August 18, 2015
asked on August 18, 2015

I am asking to see if anyone has a regular expression that would pull just the capital letters out of an expression?  For example if I have the committee name Technical Advisory Committee, I want an express that will pull just TAC.  I have tried [ABCDEFGHIJKLMNOPQRSTUVWXYZ] and \p(Lu) but each only pulls the 1st capital letter.  I have tired to use * and + and {n,} to get all but I can't make it pull all the capital letters.

 

Thanks for any help!

In-line regular expression does not support all the options you would get if you used the Pattern Matching activity. You can use Ken's workaround below or switch to using a Pattern Matching activity. I find the activity a bit more straightforward to use in this case because it has the exact options you want: case sensitiveness and combining results.

you only need to use [ABCDEFGHIJKLMNOPQRSTUVWXYZ]

I did this, and then you can use the outputted token as the value of a token, then display that token with the "Apply Index" and "all Items separated by a space, then on the token in the field after you exit the editor, remove the space in the middle of the '[ ]'

What product are we talking about? If it's either Workflow or Quick Fields, you want to set pattern matching to return "all matches" instead of "first match".

In workflow I am trying to pull just the capital letters in the token dialog box when I use the field to name something.  I want the field itself to have the committee name spelled out.  When I use it to name a document I want just the capital letters to show.

Jennifer,

You can also use [A-Z] to capture capital letters.  [a-z] captures lower-case.  This may make it easier if you have to reproduce this later on.

I can't see your full expression, does the same expression work no matter how many words are in the phrase?  Some have 3, some have 5, some have 6.
