(Please surround your code with CODE tags to keep it readable.)

If you just want to de-HTMLify a document, the fastest way I know of doing it would be to run it through lynx -dump. This even gives you a bit of formatting.

If you really need to overwrite tags with spaces, and in the proper amount, then your approach of making a pattern first and then using it is not bad, but you're making two mistakes. First, you're only making a string, not a compiled regexp. You can very easily fix that by changing your first statement to:

my $pattern = qr/  ...whatever was here before...  /;

Secondly, you are doing the work twice: first you just match for tags, then you substitute. Don't do that.

1 while $target_data =~ s/$pattern/' ' x length $1/ge;

(This is not tested! At all!)

Finally, don't use regexps to parse HTML. Use an HTML::Parser.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":



  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
    > &gt;
    [ &#91;
    ] &#93;
