在对XML内容进行解析的时候，比如用Digester将XML内容转化为Java对象时，有时会出现错误：

org.xml.sax.SAXParseException: Premature end of file

通常有两种情况会导致这种错误：

第一种：被解析的内容为空字符串

第二种：被解析的内容只有一行如：<?xml version=”1.0″ encoding=”UTF-8″?>

示例代码片断如下：

InputStream inputObject =new ByteArrayInputStream(content.getBytes(decode));
//报错行，其中content就是上述两种情况之一
digesterObj.parse(inputObject);
