將xquery結果保存到xml文件中

Question

我正在使用xqj api來實現Java中的XQuery，下面是一個示例查詢，我得到了它的工作原理。我需要將查詢的輸出寫入.xml文件，請幫助我嗎？

String queryString = 

      "declare variable $docName as xs:string external;" + sep + 
      "for $cat in doc($docName)/*/"+ objectName + 
      " where $cat/"+field+" > "+ value + 
       " order by $cat/" + field + " "+ 
      "return $cat"; 
      XQExpression expression = conn.createExpression(); 
      expression.bindString(new QName("docName"), filename, 
      conn.createAtomicType(XQItemType.XQBASETYPE_STRING)); 
      XQSequence results = expression.executeQuery(queryString); 
      System.out.println(results.getSequenceAsString(new Properties())); 

Answer 1

試試這個：

XQSequence results = expression.executeQuery(queryString); 
FileOutputStream os = new FileOutputStream(new File("output.xml"); 
results.writeSequence(os, new Properties());
