java - 转义xml中的特殊字符

Question

我在以下 xml 文件中运行此查询:

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

我收到以下错误:

ERROR]: Exception occurred, terminating. java.lang.IllegalArgumentException: Exception parsing or evaluating ClassService.getParameter(\"param1\")

如何正确转义“？

Answer 1

是否只使用 CDATA 部分来实现此目的？

 <![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？

所以它看起来类似于这样:

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