求大神解析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>

只解析DATA="ORDER_RECORD"时候的QUANTITY和 EXECUTED_QUANTITY？很急大神帮忙
[解决办法]
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());
}
