需要一些帮助来在SQLServer中创建一些XML

生成的XML应如下所示：

<?xml version="1.0" encoding="utf-8"?>
<Root Version="2.17" KFZ="XX-DD 389">
  <Head name="ExecuteAnswer">
    <Key name="AnswerStatus" value="-OK" />
    <Key name="MsgId"><![CDATA[KFHB0907896aAUH223]]></Key>
    <Section name="Command">
      <Key name="Name" value="SetNewCommand" />
      <Key name="Param0"><![CDATA[XX-DD 389]]></Key>
      <Key name="Param1"><![CDATA[]]></Key>
      <Key name="Param2"><![CDATA[0987asfdsafhdsSS]]></Key>
      <Key name="Param3"><![CDATA[0097aSSSHSDOPir0]]></Key>
    </Section>
  </Head>
  <Data></Data>
</Root>

谁能帮我一下吗

问候Alex

正如评论中指出的那样，没有理由再使用

CDATA

。。。它在语义上与正确转义的正常

text（）

节点完全相同

然而，有时遗留系统或第三方工具需要它

您必须知道：除了对

NVARCHAR（MAX）

进行强制转换并手动附加它之外，没有机会将

xml声明添加到xml中
因此，如果必须检查字符串，可以使用FOR XML PATH（）
创建干净、简单的XML，将CDATA
创建为content
并执行简单的REPLACE
将这些占位符更改为CDATA
开头和结尾字符
但是：这是一种带有显式的方法

FOR XML EXPLICIT

使用过时的选项EXPLICIT
的两个原因是CDATA
部分和一些fance名称空间问题。您是否知道，CDATA
本身已经过时了？SQL Server甚至不再支持这一点，并且在将其存储在本机XML中时将被隐式忽略。。。您真的需要这些CDATA部分吗？是的，Iam发布的XML是预先确定的。所以我必须使用CDATA属性。谢谢Shnugo！
