PDF export breaks with angle brackets inside comments

XMLWordPrintable

      JTidy doesn't correctly parse balanced angle brackets inside XML comments (<!-- ... -->). Angle brackets should be allowed as literals in this case [1], but JTidy does not do this properly.

      To replicate this, create a user macro with the following content:

      <script>
      <!--
      if (4 < 5 && 3 > 2) alert("Oops.");
      // -->
      </script>

      Include the user macro in a page, and export it to PDF. The part of the user macro following the greater-than sign is included in the PDF text.

      The same bug exists for CDATA sections and browsers do not seem to understand correctly-escaped Javascript using > and <, at least in HTML 4.0 mode.

      A workaround is to remove the greater-than sign (>) by using a negative condition.

      if (4 < 5 && !(3 <= 2)) alert("Oops.");

      This was identifed by a plugin author attempting to put commented Javascript in his Velocity template [2].
