从雪花中的 XML 中选择

Question

我正在尝试从下面 select XML 文件截图的“名称”节点，但它返回空白。 有谁知道这是为什么？ 下面是“作者”节点的 xml 代码：

  <author>
  <time/>
  <assignedEntity>
     <representedOrganization>
        <id extension="194123980" root="1.3.6.1.4.1.519.1"/>
        <name>Physicians Total Care, Inc.</name>
        <assignedEntity>
           <assignedOrganization>
              <assignedEntity>
                 <assignedOrganization>
                    <id extension="194123980" root="1.3.6.1.4.1.519.1"/>
                    <name>Physicians Total Care, Inc.</name>
                 </assignedOrganization>
                 <performance>
                    <actDefinition>
                       <code code="C73607" codeSystem="2.16.840.1.113883.3.26.1.1" displayName="relabel"/>
                    </actDefinition>
                 </performance>
              </assignedEntity>
           </assignedOrganization>
        </assignedEntity>
     </representedOrganization>
  </assignedEntity>

and here is the Snowflake code I am using:

 SELECT 
  XMLGET(name.value, 'name'):"$"::string  name
FROM 
  dailymed_xml,
  LATERAL FLATTEN(GET(src_xml, '$')) author,
  LATERAL FLATTEN(GET(author.value, '$')) time,
  LATERAL FLATTEN(GET(time.value, '$')) assignedEntity,
  LATERAL FLATTEN(GET(assignedEntity.value, '$')) representedOrganization,
  LATERAL FLATTEN(GET(representedOrganization.value, '$')) id,
  LATERAL FLATTEN(GET(id.value, '$')) name
  
WHERE 
  GET(author.value, '@') = 'author' AND 
  GET(time.value, '@') = 'time' AND
  GET(assignedEntity.value, '@') = 'assignedEntity' AND 
  GET(representedOrganization.value, '@') = 'representedOrganization' AND 
  GET(id.value, '@') = 'id' AND 
  GET(name.value, '@') = 'name';
