Grep expression between double quotes
I need a quick expression to be able to pull out all the data in a text file that looks like "http:// some random url etc" So it should grab any string that begins with "http:// and ends with " There are other double quotes in the file but I only want the ones that start with "http:// and the closing quotes for each incident of that.

I should mention the double quotes are actually in the file, I wasn't adding them myself.

pod::parselink
Pod::ParseLink(3) User Contributed Perl Documentation Pod::ParseLink(3)
NAME
Pod::ParseLink - Parse an L<> formatting code in POD text
SYNOPSIS
use Pod::ParseLink;
my ($text, $inferred, $name, $section, $type) = parselink ($link);
DESCRIPTION
This module only provides a single function, parselink(), which takes the text of an L<> formatting code and parses it. It returns the
anchor text for the link (if any was given), the anchor text possibly inferred from the name and section, the name or URL, the section if
any, and the type of link. The type will be one of "url", "pod", or "man", indicating a URL, a link to a POD page, or a link to a Unix
manual page.
Parsing is implemented per perlpodspec. For backward compatibility, links where there is no section and name contains spaces, or links
where the entirety of the link (except for the anchor text if given) is enclosed in double-quotes are interpreted as links to a section
(L</section>).
The inferred anchor text is implemented per perlpodspec:
L<name> => L<name|name>
L</section> => L<"section"|/section>
L<name/section> => L<"section" in name|name/section>
The name may contain embedded E<> and Z<> formatting codes, and the section, anchor text, and inferred anchor text may contain any
formatting codes. Any double quotes around the section are removed as part of the parsing, as is any leading or trailing whitespace.
If the text of the L<> escape is entirely enclosed in double quotes, it's interpreted as a link to a section for backward compatibility.
No attempt is made to resolve formatting codes. This must be done after calling parselink() (since E<> formatting codes can be used to
escape characters that would otherwise be significant to the parser and resolving them before parsing would result in an incorrect parse of
a formatting code like:
L<verticalE<verbar>barE<sol>slash>
which should be interpreted as a link to the "vertical|bar/slash" POD page and not as a link to the "slash" section of the "bar" POD page
with an anchor text of "vertical". Note that not only the anchor text will need to have formatting codes expanded, but so will the target
of the link (to deal with E<> and Z<> formatting codes), and special handling of the section may be necessary depending on whether the
translator wants to consider markup in sections to be significant when resolving links. See perlpodspec for more information.
