Performing complicated XPath queries in Scala

Question

What\'s the simplest API to use in scala to perform the following XPath queries on a document?

//s:Annotation[@type=\'attitude\']/s:Content/s:Parameter[@role         


        

Answer 1

I would suggest using kantan.xpath:

 import kantan.xpath._
 import kantan.xpath.implicits._

 input.evalXPath[List[String]](xp"/annotation[@type='attitude']/content/parameter[@role='type' and not(text())]/@value")

This yields:

res1: kantan.xpath.XPathResult[List[String]] = Success(List(foobar))
