I agree that only one would be enough but ...
EXPRESSION REPEREE !
Regexp: font-size:\s*[01]p[tx]\b
: =09=09<td width=3D50 style=3D'border-bottom:2px solid black;font-size:1px'>&=
Regexp: font-size:\s*[01]p[tx]\b
: font-size:1px' bgcolor=3D'black'> </td>
Regexp: font-size:\s*[01]p[tx]\b
: <td width=3D9 bgcolor=3D'black' style=3D'font-size:1px'> </td>
Regexp: font-size:\s*[01]p[tx]\b
: =09=09=09=09=09=09=09 <td bgcolor=3D'black' style=3D'font-size:1px'> <=
