提示：请直接按CTRL+F搜索您要查找的转义字符。

XML实体中不允许出现"&","<",">"等特殊字符,否则XML语法检查时将出错,如果编写的XML文件必须包含这些字符,则必须分别写成"&amp;","&lt;","&gt;"再写入文件中。例如，如果在XML文档中使用类似"<" 的字符, 那么解析器将会出现错误，因为解析器会认为这是一个新元素的开始。所以不应该像下面那样书写代码: 

Java代码  

1. <age> age < 30 </age>   

为了避免出现这种情况，必须将字符"<" 转换成实体，像下面这样: 

Java代码  

1. <age> age &lt; 30 </age>  

在读取的时候，解析器会自动将其转换回"&","<",">"等特殊字符，正常来说，只有"<" 字符和"&"字符对于XML来说是严格禁止使用的。 
需要注意的是： 
a. 转义序列各字符间不能有空格； 
b. 转义序列必须以"；"结束； 
c. 单独的&不被认为是转义开始； 
d. 区分大小写。
