How to check if NodeSeq contains a particular element

Question

I tried using "contains" function which is supposed to give a boolean if the nodeSeq contains an element, but its not working for me.

For example: seq =

<parent> <child1 /> <child2 /> </parent>

If I use seq.contains("child1"), it gives me false. Am I missing something ?

NodeSeq seems to contain a single node (you're "parent" tag) which has children. This code seems to work:

nodeSeq.child.contains(<child1 />)

Alternatively you can use xpath to find the children

(nodeSeq \\ "child3").nonEmpty == false (nodeSeq \\ "child2").nonEmpty == true (nodeSeq \\ "parent").nonEmpty == true

Thanks @AngeloGenovese. (nodeSeq \\ "child3").nonEmpty worked.

@skhaapioloir, you say this worked, but the answer has not been "accepted". Is there something wrong?
