IBatisnet中，SQL语句字符与配置文件XML保留字符冲突的区别（比如>,<等）
Escaping XML symbols
Because you are combining SQL and XML in a single document, conflicts can occur. The most common conflict is the greater-than and less-than symbols (><). SQL statements use these symbols as operators, but they are reserved symbols in XML. A simple solution is to escape the SQL statements that uses XML reserved symbols within a CDATA element. Example 3.6 demonstrates this.
Example 3.6. Using CDATA to "escape" SQL code
<statement id="SelectPersonsByAge" parameterClass="int" resultClass="Person">
<![CDATA[
SELECT * FROM PERSON WHERE AGE > #value#
]]>
</statement
