With that additional qualification, it will get a bit more tricky. My first thought was to add a space to the character class: m,"?(/[^" ]*)"?,

But that doesn't work because it won't care that it has found a space inside or outside of a quote, and will stop the regex. Meaning it would capture just "/bootMe" from the line "/bootMe any text here".

I'd suggest looking into a module like Text::xSV or Text::CSV_XS and setting the delimiter to spaces. Then reject any entry that doesn't have a leading slash. This means dropping the regex entirely.

Something like:

#!/usr/bin/perl use strict; use warnings; use Text::CSV_XS; my $csv = Text::CSV_XS->new ({sep_char => ' '}); while (my $line = <DATA>) { chomp $line; # See perldoc Text::CSV_XS for warnings # about this approach with possible embedded # newlines: my $status = $csv->parse($line); my @fields; if ($status) { @fields = $csv->fields(); } else { warn "Problem parsing $line\n"; } for my $field (@fields) { print "Captured ($field) from $line\n" if $field =~ m!^/!; } } __DATA__ "/moreIters 10" "/bootMe any text here" /fewIter /some stuff here "/albatross" foo bar baz monkeys leprechauns /not monkeys /gnomes "not leprechauns though" /gnomes more data here

Which gives the output:

Captured (/moreIters 10) from "/moreIters 10" Captured (/bootMe any text here) from "/bootMe any text here" Captured (/fewIter) from /fewIter Captured (/some) from /some stuff here Captured (/albatross) from "/albatross" foo bar baz Captured (/not) from leprechauns /not monkeys Captured (/gnomes) from /gnomes "not leprechauns though" Captured (/gnomes) from /gnomes more data here

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
