Changed regular expression to hopefully match all cases.

Sometimes it does not match correct - e.g. <tr><td>Das
Erste</td><td><span class="wochentag">So</span><span
class="datum">14.12.</span></td><td><span class="startzeit">20.15
Uhr</span></td><td>21.45 Uhr</td><td>(349) <span
class="titel">Hexenjagd</span></td></tr>
