something like this, I guess, if your two input files are doc1.xml and doc2.xml

<FF>
{doc('doc1.xml')/FNumber/meta[FileName=doc('doc2.xml')/FocalLength/meta/FileName]/
<meta>
{
let $f := FileName 
 return 
 (Value2,doc('doc2.xml')/FocalLength/meta[FileName=$f]/Value1,
 doc('doc2.xml')/FocalLength/meta/FileName[.=$f])
}
  </meta>
}
</FF>
