How to parse an XML file in Scala using VTD-XML library?

Does Anyone know How to parse large XML files using Xpa开发者_C百科th using vtd-xml library in Scala?

This works on my local machine:

import com.ximpleware.{VTDGen, VTDNav, AutoPilot}

val vtdgen = new VTDGen()
val autopilot = new AutoPilot()
autopilot.selectXPath("/CATALOG/CD/COUNTRY/text()")
if (vtdgen.parseFile("catalog.xml", false)) {
  val vtdnav = vtdgen.getNav()
  autopilot.bind(vtdnav)
  var i = -1
  while({i = autopilot.evalXPath; i} != -1) {
    println(vtdnav.toString(i))
    println(vtdnav.toNormalizedString(vtdnav.getText()))
  }
}
autopilot.resetXPath()

Outputs on input of catalog.xml:

USA
USA
UK
UK
UK
UK
USA
USA

@ huynhjl :Thank You.. It Works Well.

Use

println(vtdnav.toString(i-1))
println(vtdnav.toNormalizedString(vtdnav.getText()))

to get the output as

COUNTRY
USA
COUNTRY
UK
COUNTRY
UK
COUNTRY
USA
