Border around paragraph style after xml import

I'm struggling with my first xml import, and i'm used to work with Indesign. Below is a xml file thats generated by a database export, and will change every month.

I can without any problems formatting the rubriek_titel, titel, text. But from time the is also a kader for this I need a border and a fill color. Can some one point me out how a 'object style' (if this is correct) can be applied on aal the different objects.

Also some images are giving following problem: The selected item is hidden in overset text, It has something to do with the size of the second image. Is it possible to set a image size ?

Thanks
