------解决方案--------------------
利用dom4j进行解析

String xml="<ORDER_BOOK>" +

				"<LINEITEM DATA=\"ORDER_RECORD\" ORDER_NO=\"4172\" QUANTITY=\"2000\" EXECUTED_QUANTITY=\"2000\">" +

				"<LINEITEM DATA=\"EXECUTION\" EXECUTED_QUANTITY=\"2000\" />" +

				"</LINEITEM>" +

				"<LINEITEM DATA=\"ORDER_RECORD\" ORDER_NO=\"4173\" QUANTITY=\"3000\" EXECUTED_QUANTITY=\"1000\">" +

				"<LINEITEM DATA=\"EXECUTION\" EXECUTED_QUANTITY=\"1000\" />" +

				"</LINEITEM>" +

				"<LINEITEM DATA=\"ORDER_RECORD\" ORDER_NO=\"4172\" QUANTITY=\"2000\" EXECUTED_QUANTITY=\"0\"/>" +

				"</ORDER_BOOK> ";

		SAXReader reader=new SAXReader();

		Document doc=reader.read(new StringReader(xml));

		List<Node> list=doc.selectNodes("//ORDER_BOOK/LINEITEM[@DATA='ORDER_RECORD']");

		for(Node node:list){

			System.out.println("QUANTITY="+node.selectSingleNode("./@QUANTITY").getText());

			System.out.println("EXECUTED_QUANTITY="+node.selectSingleNode("./@EXECUTED_QUANTITY").getText());

		}
