转义xml中的特殊字符

Question

我在以下xml文件中运行此查询：

errorEvt.code===Something.CLOSE_NORMAL

我收到以下错误：

  

ERROR]：发生异常，终止。   java.lang.IllegalArgumentException：异常解析或评估   ClassService.getParameter（\＆＃34;参数1 \＆＃34）

如何逃避＆＃34;正确？

Answer 1

为此只使用CDATA部分怎么样？

 <![CDATA[
 Within this Character Data block I can
 use double dashes as much as I want (along with <, &, ', and ")
 *and* %MyParamEntity; will be expanded to the text
 "Has been expanded" ... however, I can't use
 the CEND sequence (if I need to use it I must escape one of the
 brackets or the greater-than sign).
 ]]>

或者这不符合您的要求吗？

所以它看起来与此相似：

<?xml version="1.0" encoding="UTF-8"?>
..
...
<query> 
     <![CDATA[
     update tableX set colName='$ClassService.getParameter(\"param1\")$' where id = '0'
     ]]>
</query>
...
