This is what i am trying to do:

 The output from GetPages contains many attributes that are unnecessary for our work. Use Select Attributes to discard every attribute except URL and Document.

When i try and do this i cannot select the ones i want to keep and the dataset i am using are wiki articles

    Hi @ced57,

    "i cannot select the ones i want to keep" ==> what is exactly your problem ?
    If the attributes of your dataset don't appear in the Select Attributes operator's dialog box, 
    you can follow these steps :  

    I hope it helps,

    Regards,

    This is another metadata propagation problem.  It is annoying, but not insurmountable.  You can always type the names of the attributes you want directly as @lionelderkrikor shows.  You can also use another trick if there are only a couple of attributes you want.  Use the Set Role operator to give each of them a special role, then use Select Attributes and leave it blank, but use the "invert selection" operator.  This should get rid of everything except your special attributes.
