Fergal,

I have no doubt you are right regarding the behavior of Petal. However,
the correct behavior is not always the optimal behavior. Here's an
example of a JavaScript that will fail when passed through Petal:

  <script type="text/Javascript" language="Javascript">
    var d;
    d = '1' & '1';
    alert(d);
  </script>

The '&' which does a comparison in the same way that Perl's own && gets
converted to &amp;. Unfortunately, the browser does not treat this
entity as a comparison operator.

Any advice on how to make this work without using an external Javascript
file would be appreciated.


William
