[Rt-devel] html/Elements/ScrubHTML correction

[akos.torok at docca.hu]

Hi All,

I think there is a tag missing from the scrubber-allow: <pre>.

Affected RT version
==============
Our RT is 3.4.4pre

Problem:
======
By using PreferRichText sometimes the text appears without formatting.

Reason
=====
The problem occures when the richtext is not a normal html doc, but a 
classic text (I mean: linebreak is chr(13) not <br> and spaces are 
spaces). In a html document a part like this has to be enclosed by <PRE> 
and  </PRE> ('pre' means preformatted text). The bug: after these tags 
have been eliminated by the scrubber, the text will have displayed 
without formatting (no line breaks, no tabs, no spaces).

Resolution
=======
Insert PRE into the scrubber's allow string. Original file: 
RT3PATH/share/html/Elements/ScrubHTML, line 64.

$scrubber->allow(
    qw[A B U P BR I HR BR SMALL EM FONT SPAN DIV UL OL LI DL DT DD PRE]);
