Xml demos

Basic XML with scala:
Note you can also use the CDATA command but blogger didn't like me having that here!

  def xmlDemo() : Unit = {
    val xml = <>my xml
      <>1< /val >
      <>2< /val >
      < /b >
    println( xml.length )
  }

Filtering XML:
loads XML,
finds how many 'para' tags are in the XML
prints all the 'id' attributes of the 'sect2' tag
Note: \\ means find anywhere \ means find one level down

    val xml3 = XML.load("http://www.linux.sgi.com/LDP/authors/template/Sample-HOWTO.xml")
    println( (xml3 \\ "para").length )
    println( (xml3 \\ "sect2").map(_ \ "@id").map(_.text) )

Transforming XML:
find any nodes which have an 'id=copyright' attribute and remove them

    val moveIt = new RewriteRule {
      override def transform(n : Node) : NodeSeq = n match {
        case e:Elem if (e \"@id").text == "copyright" => NodeSeq.Empty
        case e => e
      }
    }
    println( new RuleTransformer(moveIt).transform(xml3) )
