Regexp::Common::delimited(3pm)				User Contributed Perl Documentation			    Regexp::Common::delimited(3pm)

NAME
Regexp::Common::delimited -- provides a regex for delimited strings SYNOPSIS
use Regexp::Common qw /delimited/; while (<>) { /$RE{delimited}{-delim=>'"'}/ and print 'a " delimited string'; /$RE{delimited}{-delim=>'/'}/ and print 'a / delimited string'; } DESCRIPTION
Please consult the manual of Regexp::Common for a general description of the works of this interface. Do not use this module directly, but load it via Regexp::Common. $RE{delimited}{-delim}{-esc} Returns a pattern that matches a single-character-delimited substring, with optional internal escaping of the delimiter. When "-delim=S" is specified, each character in the sequence S is a possible delimiter. There is no default delimiter, so this flag must always be specified. If "-esc=S" is specified, each character in the sequence S is the delimiter for the corresponding character in the "-delim=S" list. The default escape is backslash. For example: $RE{delimited}{-delim=>'"'} # match "a " delimited string" $RE{delimited}{-delim=>'"'}{-esc=>'"'} # match "a "" delimited string" $RE{delimited}{-delim=>'/'} # match /a / delimited string/ $RE{delimited}{-delim=>q{'"}} # match "string" or 'string' Under "-keep" (See Regexp::Common): $1 captures the entire match $2 captures the opening delimiter (provided only one delimiter was specified) $3 captures delimited portion of the string (provided only one delimiter was specified) $4 captures the closing delimiter (provided only one delimiter was specified) $RE{quoted}{-esc} A synonym for $RE{delimited}{q{-delim='"`}{...}} SEE ALSO
