get xml value

<filmlist>   <user num="1">     <film>clip02.flv</film>     <film>clip01.flv</film>   </user>   <user num="2">     <film>clip01.flv</film>     <film>clip02.flv</film>   </user>   <user num="3">     <film>clip02.flv</film>     <film>clip01.flv</film>   </user> </filmlist>

I know how to get the 'film' values between those tags. E.g. userFilms_XML.user[3].film[2]. What I don't know is how to target the 'num' value in each 'user' tag. Can I read num="1" e.g. too? Something like userFilms_XML.user[3].num so it would trace '3'.
