How do i replace only digits attached with letters

[Ebenezer Amoako Yirenkyi]

i have
PTH 284 Wo, mm4b chunu Awurade
and i want to change only the 4 within the string without affect the 284
so i want to change 4 to e
so the result i need is
PTH 284 Wo, mmeb chunu Awurade

@Ebenezer-Amoako-Yirenkyi

given your requirement one possible solution would be to
search for \d(?=[a-zA-Z]) , replace with e and
having search mode regular expression checked.

If the requirement is that the digit is surrounded by letters, then
search for (?<=[a-zA-Z])\d(?=[a-zA-Z])

ello @ebenezer-amoako-yirenkyi and All,

To change any number, embedded in letters of a word, use the following regex S/R :

• Open the Replace dialog ( Ctrl + F )

-SEARCH (\p{alpha})\d+(?=\p{alpha})

• REPLACE ${1}Your replacement ( So ${1}e, in your case )

• Tick the Wrap around option, if necessary

• Select the Regular expression search mode

• Click once the Replace All button or several times on the Replace button

Best Regards

Of course you meant Ctrl + h for this.

Nice use of \p{alpha} from the Character Properties table on this PAGE which has a link that lead to HERE and then finally HERE to find “alpha”.

Perhaps \p{space} will start getting more use as a more “readable” way of searching for whitespace? Although I’d have to go off and figure out exactly what types of whitespace it matches. :-)

I also noted your use of ${1} in the replacement, rather than the usual \1. I think that is a good thing, because it looks “cleaner”, it features no “leaning toothpick”, and it works when the number part is > 9.

Or you could go to our documentation on character properties which direct you to the big old table of valid names right above. :-)

Yea, since “our” docs on this are pretty much a verbatim copy of the original, I like to go back to the original, because of the “typo” potential in the copy/edit. :-)

Actually, @guy038 did that work back in November: [\t\n\x0B\f\r\x20\x85\xA0\x{2028}\x{2029}]
(merged in PR#59 ) …

edit: and you would have seen that if you used “ours” instead of “theirs” ;-)

Hi @ebenezer-amoako-yirenkyi @alan-kilborn, @peterjones and All,

Alan, I used the ${1} syntax because I was afraid that, in case you would have preferred to change the 4 digit, by any number, this would not work.

Luckily, I realize that I was wrong because, for instance, the syntax \123, in replacement, always means change current match with contents of group 1, ( even if not defined => an empty string), followed with the number 23

So, the two replacement syntaxes \1Your replacement or ${1}Your replacement are safe ! Unlike the third syntax $1Your replacement which is best to avoid when your replacement is a number !
