How do I just grab specific areas of a site, e.g:
<http://library.digiguide.com/lib/programmenextshowing/Police%2C+Camera%2C+Action%21-12578>
<http://library.digiguide.com/lib/programme/Police%2C+Camera%2C+Action%21-12578/Entertainment/>
<http://library.digiguide.com/lib/programme/Police%2C+Camera%2C+Action%21-12578/Documentary/>

which I tried to grab, but ended up getting the bits I don't want, so how do I
restrict it to just the Police%2C+Camera%2C+Action%21-12578 and /episode/
directories??
