 Thanks andrew, but I don't know how I could use it (plus I think you have
missed that item-filter is not child of body but it's brother), could you
please write complete select for me?

 Great, this works, thanks!

 But xsl:key must be top-element, what if I had following structure:

      <item pos="1" name="n1"/>
      <item pos="2" name="n2"/>
      <item pos="3" name="n2"/>
      <item pos="4" name="n3"/>
      <item pos="5" name="n4"/>
         <allow-items with-name="n2"/>
         <allow-items with-name="n4"/>
      <item pos="1" name="n2"/>
      <item pos="2" name="n3"/>
      <item pos="3" name="n5"/>
         <allow-items with-name="n3"/>

and wanted to filter items of each body element by it's own item-filter?
