title: Which XPathAPI should I use in Java 1.5?
body: <p>I have been using com.sun.org.apache.xpath.internal.XPathAPI for some time and it seems to work ok. Recently I tried to use the TPTP profiler in Eclipse but it could not find the XPathAPI class.</p>
  
  <p>I haven't figured this problem yet but it did make me wonder whether I should be using a class in an 'internal' package? Should I be using the Xalan library? Or what??</p>
  
  <p>(I'm currently using JRE 1.5.0_06 for this project)</p>
