You could try something like this, i.e. put your not-to-be-replaced entites into a hash for easy lookup:

#!/usr/bin/perl my %entities = map { $_ => 1 } qw(&amp; &quot; &lt; &gt; &nbsp; &copy; +); while (my $line = <DATA>) { $line =~ s/(&(\w+?;)?)/exists $entities{$1} ? $1 : "&amp;$2"/eg; print $line; } __DATA__ foo &amp; &quot; bar &blah; &foo baz & ... TEST&TEST;A&E&an &nbsp; HTML--- &nbsp; string - &lt; &copy; TVS&gt;

Would output:

foo &amp; &quot; bar &amp;blah; &amp;foo baz &amp; ... TEST&amp;TEST;A&amp;E&amp;an &nbsp; HTML--- &nbsp; string - &lt; &copy +; TVS&gt;

(note that if you run this under strictures, it'll complain "Use of uninitialized value in concatenation" in case $2 is empty... I'll leave this as an exercise for you to fix :)

Update: I hadn't followed your other thread... so looking at wfsp's solution there, I'd say just use that instead and be happy :)

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
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.
