As you probably know, an XPath 2.0 expression returns a sequence of items (nodes and atomic values). The following code shows you how to read from a sequence of items in Saxon 8. The code identifies the nodes and atomic values and calls the correct methods for showing them.
...
List L=null;
...
try
{
//this XPath expression returns a sequence of nodes
L=XPE.evaluate("/company/departments/");
//this XPath expression returns an atomic value
//L=XPE.evaluate("5 instance of xs:integer");
}catch(net.sf.saxon.trans.XPathException e)
{System.out.println(e.getMessage());}
//processing the resulted sequence
if(L!=null)
{
for(Iterator iter=L.iterator();iter.hasNext();)
{
Object obj=(Object)iter.next();
if(obj instanceof NodeInfo)
{
NodeInfo NI=(NodeInfo)obj;
String info=net.sf.saxon.type.Type.displayTypeName(NI);
System.out.println("INFO:["+info+"]");
System.out.println("VALUE:["+NI.getStringValue()"]");
}
else
{
String val=String.valueOf(obj);
System.out.println("ATOMIC VALUE:"+val);
}
}
}
}
