/** Check that the XMLs are the same, ignoring empty text nodes (whitespace). */
private def assertEqual(actual: xml.Node, expected: xml.Node) {

    def recurse(actual: xml.Node, expected: xml.Node) {
        // depth-first checks, to get specific failures
        for ((actualChild, expectedChild) <- actual.child zip expected.child) {
            recurse(actualChild, expectedChild)
        }
        actual should be (expected)
    }

    recurse(scala.xml.Utility.trim(actual), scala.xml.Utility.trim(expected))
