RegExp and search / replace question - removing "" when around a single word without whitespace

[Rainer Krug]

Hi

I had a regex but can't find it anymore (I found the "Manage Pattern" only now - it always reminds me of Google...).

Could somebody give me a regex which removes the `"` around "this" word, but not "this word"?

Thanks

Rainer

can you be more specific? What is the determining factor?

• Exactly "this" > this
• Only single words

pls give some examples of before and after so we can see logic. thanks.

Sure.

Should be removed: (single words without whitespace or "-")

"singleword" -> singleworls

"Hello" -> Hello

" Hello" -> Hello [whitespace after removal of " do not matter]

" Hello " -> Hello

"Hello " -> Hello

Should NOT be removed: (strings with whitespace or "-" except ), i.e. remain unchanged

"Hello World" 

"Hello big world"

"tomato-sauce"

" Hello World "

Hope this helps,

Maybe this will help?

Building on Kerri's solution to include non-breaking spaces, tabs and linefeeds, etc.

find:

"[\s\N{U+00A0}]*([^\s\N{U+00A0}"-]+?)[\s\N{U+00A0}]*"

replace:

\1

Oops, previous regex will flag :

"tomato-sauce" or "mayonnaise-sauce"

This one is a bit more strict:

(?<=\s)"[\s\N{U+00A0}]*([^\s\N{U+00A0}"-]+?)[\s\N{U+00A0}]*"

But it will still flag (see the space after tomato-sauce) :

"tomato-sauce " or "mayonnaise-sauce"

There might be more edge cases, so be cautious.

Thanks Kerry and Jean - they look great. I will try both in real-world cases soon and come back if there are major problems I can't solve (likely any which involve modifying the regex...).

The regex will be used for text files with max about 100 lines - so a visual check afterwards is possible and in any case high;y advised.

Thanks a gain
