How to Use Oracle Java XQuery API

This code outlines the main steps involved in using the Oracle Java XQuery API (OJXQI). If you are familiar with the DataDirectXQuery - XQuery for Java (DDXQ-XQJ), you may notice a some similarities.

XQueryContext XQC=new XQueryContext(); 

 try 
   { 
   //the XQuery query is in a file called Q.xquery
   //the XML file must be specified into the
   //Q.xquery by the fn:doc XPath function - of course
   //if you are using an XML Reader R=new FileReader("Q.xquery"); 

   //"prepare" the query
   PreparedXQuery PXQ=XQC.prepareXQuery(R); 
   
   //getting the results
   XQueryResultSet XQRS=PXQ.executeQuery(); 
   while(XQRS.next()) 
     { 
     XMLNode node=XQRS.getNode();
     node.print(System.out); 
     } 
   } 
   catch (Exception e) 
   { 
    
   }
