Is it possible to use regEx to remove spaces before and

Example :
my " beautiful " laundrette

my "beautiful" laundrette

(?<=") \ + (?= [^"]* " (?>(?:[^"]*"){2})* [^"]* \z)

\ + (?= " (?>(?:[^"]*"){2})* [^"]* \z)
on mouseUp
put replaceText(field "In",field "regex","") into field "Out"
end mouseUp
This is slow for long strings. The regex experts might have some
ideas on how to speed that up. For every match it has to check the
rest of the string to make sure the quotes pair up. Ow.
This uses assertions to get around the whole-match nature of
replaceText().
The \ + matches the spaces to be removed. The (?x) allows me to use
whitespace in the regex.
In the lines of the regex the part before the space matching is the
lookbehind assertion and the part after is the lookahead assertion.
To create the regex, I'd use format() which allows a special \"
notation for literals in the first parameter, but the usual '& quote
&' method will also work.
This pairs quotes from the right, so if the quotes are not paired,
this will goof up at the start of the string.
