Saxon

Hi List, Thanks in advance for the help. I'm doing some java work for the first time in a long time and needed an XSLT 2.0 processor so got Saxon9. Since I was using saxon for transformations thought I might as well use it for XPath as well. The problem is the rest of the program relies on Nodelist. According to the java samples and some online searching it seems that I "should" be able to cast a Nodeset to a NodeList, however I am getting errors. Any help would be appreciated. public static void main(String[] args) throws Exception { String sXml = "<?xml version=&quot;1.0&quot;?>" + "<root><test id=&quot;1&quot;>Test</test>" + "<test id=&quot;1&quot;>Other Test</test></root>"; StringBuffer sb = new StringBuffer(sXml); ByteArrayInputStream bis = new ByteArrayInputStream(sXml.toString().getBytes()); System.out.println(Saxon.getStringResults("//test[@id = '" + 1 + "']", bis)[0]); } public static NodeList getNodeResults(String sXPath, ByteArrayInputStream xml) throws XPathFactoryConfigurationException, Exception { System.setProperty("javax.xml.xpath.XPathFactory:http://java.sun.com/jaxp/xpath/dom", "net.sf.saxon.xpath.XPathFactoryImpl"); XPathFactory xpf = XPathFactory.newInstance(NamespaceConstant.OBJECT_MODEL_SAXON); XPath xpe = xpf.newXPath(); InputSource is = new InputSource(xml); SAXSource s = new SAXSource(is); NodeInfo doc = ((XPathEvaluator)xpe).setSource(s); XPathExpression xPath = xpe.compile(sXPath); NodeList nodes = null; try { nodes = (NodeList)xPath.evaluate(doc, XPathConstants.NODESET); } catch (Exception e) { e.printStackTrace(); } return nodes; } Error happens at the line: nodes = (NodeList)xPath.evaluate(doc, XPathConstants.NODESET); StackTrace: java.lang.ClassCastException: java.util.ArrayList cannot be cast to org.w3c.dom.NodeList at reconsearcher.util.Saxon.getNodeResults(Saxon.java:85) at reconsearcher.util.Saxon.getStringResults(Saxon.java:95) at reconsearcher.util.Saxon.main(Saxon.java:51) Exception in thread "main" java.lang.NullPointerException at reconsearcher.util.Saxon.main(Saxon.java:51) Any thoughts on where I'm going wrong? Thanks, Spencer
