Re: Unescape characters from XML::Twig

My mistake! When I first wrote XML::Twig I only used it to output back XML. Outputting HTML or plain text came later. So there you have a bug!

The next version (XML::Twig 3.0) will fix this. I will properlly store the ' as... ' and only turn it into ' when using the print or sprint methods, the text one will leave it as '

In the meantime you can unescape the text using this:

sub unescape
  { my $text= shift;
    $text=~ s/&lt;/>/g;
    $text=~ s/&gt;/</g;
    $text=~ s/&quot;/"/g;
    $text=~ s/&apos;/'/g;
    $text=~ s/&amp;/&/;
    return $text;
  }

By the way, if you have tag-heavy XML you can also use CDATA sections: if you replace your string by the following one it will work (nearly, there is a definite bug there, as opposed to a poor design decision, which turns the & into &):

qq{<?xml version=\"1.0\"?><TEST><LINK><TITLE><![CDATA[This < is a > " test ' & don't you forget it]]></TITLE></LINK></TEST>}

Minor correction, the line: `$text=~ s/&/&/;` should be: `$text=~ s/&/&/g;`.	[reply] [d/l] [select]
