( [id://3333]=superdoc: print w/replies, xml ) Need Help??

Maybe a little something like this?

my $string = q{ 1. This is just a sample. 2. This is to check 3. How a set of values 4. can be replaced by another 5. set of values and that too 6. in the most efficient way. }; my %replacements = ( '1.' => 'a.', '2.' => 'b.', '3.' => 'c.', '4.' => 'd.', '5.' => 'e.', '6.' => 'f.', ); my $regexp = join '|', map quotemeta, keys %replacements; $string =~ s/($regexp)/$replacements{$1}/g; print $string;
perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'

to format your post; it's "PerlMonks-approved HTML":



  • 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).
  • Want more info? How to link or How to display code and escape characters are good places to start.
