asp.net regex find items in quotes

Luis Esteban Valencia

hello quite a simple one if you understand regular expressions vbscript and
..net, probably quite hard if you don't

i have a single line input which offers classic search functionality, so if
someone puts something in quotes i.e "A Gibbon" i want to extract that prior
to using the rest of the string

what i need is a regex string that'll turn a postback string eg "A Gibbon"
"A Baboon" "George Bush" doris day into a csv array

("A Gibbon", "A Baboon", "George Bush", "doris", "day")

i can probably handle the doris day after i have got the quoted items

sub btnSearch_clicK ()
dim strtext as string = inpSearch.text
dim srchArr as string
so dim myRegEx as new regEX( .....find all items in quotes)

srchArr = myRegEx.Replace ( strtext, ...... )

any ideas?

I believe there was an article similiar to this in the Nov. 2004 Visual
Studio magazine. "Parsing text files using Regular Expressions". And I
said to myself. Who in the world would need to do that! There has to be
an easier way. Now I see that I was wrong. Sorry.

My suggestion is go to the magazine site and search for the article. It
might help

Not being a regex expert myself, the easy hack would be to do it in two
passes.

Pass 1: Get the quoted strings...

use regex... (\".*?\")
means: "get me anything that begins with a quote, maybe contains some
characters, and ends with a quote. no backtracking."
iterate through the groups
append these to your array
then replace all of the quoted strings with a space to avoid re-matching on
pass 2

Pass 2: Get the non-quoted strings...

use regex... ([^\s]+)
means: "get me any sequence of non-whitespace characters."
iterate through the groups
append these to your array
You might also have better success posting this in a regex-specific
newsgroup, or Google "csv regex" which is closely related to what you're
pursuing.

Regex help, please - Recognize quoted strings?

I'm struggling with something that should be fairly simple. I just don't know the regext syntax very well, unfortunately. I'd like to parse words out of what is basically a boolean search string. It's actually the input string into a Microsoft Index Server search. The string will consist of words, perhaps enclosed in quotes or parentheses. I'd like to use Regex to pull out the words, or the phrases if the words are enclosed in quotes....
