mysql - Mysql - 分隔符之间多次出现字符串

Question

我正在尝试从包含中文本 XML 格式的数据的表中获取以下结果。

我希望在开始分隔符 L7p:AuditDetailAssertion 和下一次出现的结束分隔符 /L7p:AuditDetailAssertion 之间出现所有文本。

然而，困难的部分是这些字符串可能出现一次或多次。

这是选择它时 XML 在列中的显示方式：

需要的输出：

L7p:Detail stringValue="${secpass.blah.plaintext}"/
L7p:Enabled booleanValue="false"/
L7p:Detail stringValue="auditOnFailure: routingStatus: ${response.http.status}"/
