如何拆分一个字符串两次
我试图将字符串拆分两次
String example = response; String [] array = example.split(""); System.out.println(array[0]); String [] array2 = example.split(""); System.out.println(array2[2]);</code> </pre>
<p> 我试图通过使用此代码（不成功）来实现这一点，但不是打印第一个分割我想保存它并继续进行第二次分割。 谁能解决这个问题，或者更好地解决两次分裂问题？ 谢谢 </p>

<p> 这可能看起来很多……但你真的应该使用DOM解析器来操作XML： </p>
