    <description>&lt;HTML&gt;&lt;HEAD&gt;&lt;/HEAD&gt;&lt;BODY&gt;&lt;P&gt;Hello,&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;I am trying to make a custom signature using a pattern match that looks for 42 characters 0-9 A-F in the http post field. I tried [0-9A-F]{42} and a few variations but nothing I try works.&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Is there a way to use this sort of data pattern in PAN?&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;Thanks for any help,&lt;/P&gt;&lt;P&gt;&lt;/P&gt;&lt;P&gt;-James&lt;/P&gt;&lt;/BODY&gt;&lt;/HTML&gt;</description>
