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)    {        }
