Testing XML attributes in Scala

Suppose I have an XML and map


val xml = 
<a>
   <b x="x1" y="y1"/>
   <b x="x2" y="y2"/>
   <b x="x3" y="y3"/>
</a>

val m = Map("x1" -> "y1", "x2" -> "y2", "x3" -> "y3")

I am fetching <b> elements from XML and checking if the elements contain x and y attributes as in the map m.


val bs = xml \\ "b"
((bs \\ "@x").map(_.text) zip (bs \\ "@y").map(_.text)).toSet == m.toSet

Does it make sense ? How would you fix/improve this code ?
