At worst, another way with the ternary (or "conditional") operator:
use vars qw ( $message); $message = qq ( Foo bar <font size="7"> phrase here </font> blivits. ) +; $message =~ s#(\d+)#($1 > 5) ? 5 : $1#eisg; if ( $1 ) { print "\n After s###, \$1 is: $1 \n ...and revised \$msg is: +$message \n"; } else { print "\n no \$1 found \n"; }
and output is:
After s###, $1 is: 7
...and revised $message is: Foo bar <font size="5"> phrase here </font> blivits.
  • the $message html fragment is well-formatted... for 4.0, but display elements are now better (well, that's what the experts say) done with css
  • the "sig" regex modifiers are not needed with this $message but might well be with more typical .html
  • and, while matching on <font size=" before the 7> is omitted only to keep the example simple (and is easy enough to add), this is a very limited and profoundly un-extensible method -- better to use an html parser, as suggested elsewhere. For example, a web'ster using <font... may well have multiple and/or variant forms of elements in a single font tag, as, for example,
    <font color="red" size=+1...>
  • and, finally, despite generous efforts by OP, I can't see how Re^2 or Re^3 can or do work ... even with "<"s replacing "["s would welcome education.

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.
