特殊字符 转义对照。如 < >

一般是html的转义，xml也适用

但是在写sql时，xml文件中会出现。







转义方法
public static String htmlReplace(String str){
str = str.replace("“","“");
str = str.replace("”","”");
str = str.replace(" ","”");
str = str.replace("&","&");
str = str.replace("'","'");
str = str.replace("’","’");
str = str.replace("—","—");
str = str.replace("–","–");
str = str.replace("<","&lt;");
str = str.replace(">","&gt;");
return str;
}
