whitespace remove

Discussion in 'Perl' started by abhisheksainiabhishe, Jun 11, 2008.

  1. If I have a multiline text like..

    abcd ef ghi
    xyz d e f
    d
    sjskf s fdf

    then how would I be able to remove the spaces (/s+) inside the strings (in middle of the strings).

    I thought using doing like...

    $string =~ s/\s+/ /g;

    would work. but it does not work.

    And if above is the way I would end up finally then can I make it like so it would
    not alter spaces within <pre> tags like....

    #declaring pretags avlyes
    my $startPreTag="<pre>";
    my $endPreTag="</pre>";


    #so the spaces (more than one) will be removed is it is not enclosed by pre tags
    $string =~ s/[^$startPreTag]^\s+[^$endPreTag]//;

    Please tell me if I am on the right track

    None of my appraoches are working. Please advise. Thanks!

    You expression looks like having a space in the replacement portion,
    Code:
    # Your version
    $string =~ s/\s+/ /g;
    # Right code
    $string =~ s/\s+//g;
    
    For replacement within PRE tags,
    Code:
    $string =~ /<pre>([^<]+)<\/pre>/gi;
    $str = $1;
    $str =~ s/\s+//g;
    $string =~ s/<pre>([^<]+)<\/pre>/$str/;
    
    This will work only if there is only one occurance of pre in the string, you can also try HTML::parse for this purpose.
     
  3. got it.
    thanks!
