java获取xml格式字段数据

public static void main(String [] args){

String result1="<?xml version=\"1.0\" encoding=\"UTF-8\"?><bill><id>4028a8973f5c45db013f5c61fb8f0002</id><ProofBillBarCode>B11000000000020130600003</ProofBillBarCode><proofInfo id=\"4028708c3f552dbd013f552dbd140000\">W11000000000020130600001</proofInfo></bill>";

try {

System.out.println("根节点"+books.getName());

// Iterator users_subElements = books.elementIterator("UID");//指定获取那个元素
