Simple Scala XML Parsing
//val xmlNode = xml.XML.loadFile("xxx")
val xmlNode =
<persons>
<person age="30">
<name>bob</name>
</person>
<person age="40">
<name>joe</name>
</person>
</persons>
val personNodes = xmlNode \\ "person"
personNodes.map(personNode => personNode \ "name")
//List(NodeSeq(<name>bob</name>), NodeSeq(<name>joe</name>))
personNodes.flatMap(personNode => (personNode \ "name").map(nameNode => nameNode.text))
//List(bob, joe)
personNodes.map(personNode => personNode \ "@age")
//List(30, 40)
