help with regex for fixing misspellings please

cybmole · 01-11-2011, 06:25 AM

i have a book in which all instances of words containing ll are ocrrupt. the double l is mis-scanned as a single l + a space i.e. follow has become fol ow.

I tried to construct a regex to use in find + replace so that I could make a replace or find next choice on every hit.

the find is easy \wl w\
but I cant figure the replace syntax to take the found expression, reuse the word boundary characters, and substitute ll for l+space. it's reusing the word boundary detects that is baffling me.

i shoudl probably also make use of the fact the ll occurs only after a vowel ( i think) in correctly spelled english
so something like this would be better for the find expression ?
[AEIOUaeiou]l \[a-z]
i still then need to reuse the "found" characters

Paren around groups. \a_digit to reuse groups found

Match case:
S: ([AEIOUaeiou]l) (\[a-z])
R: \1l \2

But STOP

thanks - I looked up some syntax help & realised I'd not used ( ) which are needed for \1 \2 etc operations

i've now fixed most instances by doing replace all on the messed up common 3 & 4 letter words one at a time - like fil wil fel tel til tal, then all of the "l y " endings.

it made me think quite hard about how to define valid instances of ll and also made me appreciate the occasional inconsistency- like the example you gave, & also odd words like belief that break the double l after a vowel "rule"
