GREP Expression help

[Catharine26941291c64a]

Sorry to bother, but I'm still struggling with GREP! I need an expression that superscripts the numbers at the start of a string of references - for example:

1Princess Margaret Hospital, Toronto, ON, Canada; 2University of Manitoba, Winnipeg, MB, Canada; 3London School of Economics, London, UK; 4Hospital Universitario 12 de Octubre Madrid, Spain.

The references need to remain a single line,  each reference separated by a semicolon, and the digits can typically include up to 2 characters. As in my example, the names can include digits at times, so those would have to be excluded from superscripting. Help!

I can make this work with two expressions aaplied as GREP styles separately, but not as a single expression that catches all cases.

^/d+ catches the initial digit, and (?<=; )\d+ catches the ones after.

Hi. 
^/d+ isn't catching the first digit for me, but if I put parenthases around the caret, it works - not sure if that will create other issues, but if works for now! Thanks Peter

It's a typo: the slash should be a backslash: ^\d+

[Peter Spier]

OOOPS.

Thanks, Peter

[Peter Kahrel]

A typo on my part caused a single expression to work:

((; \K)|)\d+

No idea why that works though.

[Catharine26941291c64a]

😄 as long as it does!! Thanks again.

Still need the two-style solution as this single one also catches the number 12 in the Spanish hospital title

[Peter Kahrel]

In that case use

((; \K)|)\d+(?=\u)

which stipulates that the number should be followed by an upper-case letter.

[Peter Spier]

@Peter Kahrel any idea why ^\d+|(?<=; )\d+ doesn't work? For me it only captures the first number after the ; and nothing else.

[Catharine26941291c64a]

I had to put parentheses around the first caret - that worked for me, anyway

[Peter Spier]

OK, That's pretty  strange to my way of thinking. It doesn't work if you put parentheses around the whole ^\d+

[Peter Kahrel]

I've no idea. I tried that one, in fact. So I don't know why this one doesn't work, and I don't know why the one I hit on accidentally does.

A grep style in a paragraph style applying a character style with superscript works also.

\d+(?=\u)

OR

\d{1,2}(?=\u)

OR (if there are lowercase letters starting the name)

\d+(?=\u|\l)
