android 手机端从服务器端读取数据库的文件，抛出异常：：报错

我把从网络读取的数据流转化字符串，用的方法是：

int b;
StringBuffer sb = new StringBuffer();
while((b = in.read())!=-1 ){
sb.append((char)b);
}
System.out.println(sb);

打印出来:

这就证明读取到了网络的xml，但是解析的时候出来问题。

接着我在本地的assets文件夹里写了一个xml文件：

<?xml version="1.0" encoding="utf-8"?>
<menulist>
<menu>
    <id>1</id>
    <name>张三</name> 
</menu>
<menu>
    <id>2</id>
    <name>李四</name> 
</menu>
<menu>
    <id>3</id>
    <name>王五</name>
  </menu>
<menu>
    <id>4</id>
    <name>高小小</name>
</menu>
<menu>
    <id>5</id>
    <name>李大大</name>
 </menu>
<menu>
    <id>6</id>
    <name>郭剩剩</name> 
</menu>
</menulist>

用同样的解析方法，可以解析出来，并且保存到SQLite数据表中。

这样看来是不是因为网络读取的xml文件格式有问题，所以导致的解析错误呢？

因为网络的xml是根据服务器的数据库文件自动生成的，所以到底该怎么弄呢？我没思路了又
