Question

我在postgresql表中有一个xml类型列。我正在尝试使用表的某些列（也包括XML类型列）创建新的xml。

对于内部XML，我得到了" > 
 <等特殊字符。

如何获取实际的标签和符号而不是这些字符？

下面是内部XML示例

<Detail>
    <RuleDetail Name="Test">
      <If>
        <Conditions>
          <Condition ConditionID="E4A073ED-A572-4CC5-AC68-835445C0DB6F"/>
        </Conditions>
        <Actions>
          <Action ActionID="A959CF33-3537-486A-B6BB-2DBDFD7B32B9"/>
        </Actions>
      </If>
    </RuleDetail>
</Detail>

下面是外部XML输出

<?xml version="1.0" encoding="UTF-8"?>
<Rules>
   <Rule RuleID="6df3b89e-ef0f-4016-936c-0138d80b0c4e" Name="TODO: test1" SectionID="c8030a47-aa34-4d51-84ff-dcfe11e05599" Detail="&lt;Detail&gt;&#xA;    &lt;RuleDetail Name=&quot;Test&quot;&gt;&#xA;      &lt;If&gt;&#xA;        &lt;Conditions&gt;&#xA;          &lt;Condition ConditionID=&quot;E4A073ED-A572-4CC5-AC68-835445C0DB6F&quot;/&gt;&#xA;        &lt;/Conditions&gt;&#xA;        &lt;Actions&gt;&#xA;          &lt;Action ActionID=&quot;A959CF33-3537-486A-B6BB-2DBDFD7B32B9&quot;/&gt;&#xA;          &lt;/Actions&gt;&#xA;      &lt;/If&gt;&#xA;    &lt;/RuleDetail&gt;&#xA;  &lt;/Detail&gt;" AddedDate="2019-03-07T13:46:13.543" DeleteFlag="false" />
</Rules>

下面是我正在使用的查询

Select   XMLELEMENT(name "Rules",XMLAGG(XMLELEMENT(name "Rule", XMLATTRIBUTES(RuleID as "RuleID", Name as "Name", SectionID as "SectionID", Detail as "Detail", AddedDate as "AddedDate", ModifiedDate as "ModifiedDate", DeleteFlag as "DeleteFlag"))))
From RuleDetail

详细信息列为XML类型

嵌套XML具有特殊字符而不是标签
