在配置单元中使用XMLSerDe进行XML文件配对时出现问题

下面是我的输入XML

 <entity>
  <link idType="ProviderId">AEY000977645</link>
  <link idType="PAID">000977645</link>
  <link idType="PID">AEY</link>
  <message reason="Not Currently In TMS Database" status="Unmappable"/>
 </entity>

AEY000977645
000977645

我需要解析这些数据，并使用hivexmlserde创建一个包含4列（ProviderID、PAID、PID、message_reason）的配置单元表。因为所有的值都在标记内，所以很难解析数据。下面是我的表格DDL

CREATE EXTERNAL TABLE xml_testing
(
         provider_id    String,
         paid           String,
         pid            String,
         message_reason String
)
ROW FORMAT SERDE 'com.ibm.spss.hive.serde2.xml.XmlSerDe'
WITH SERDEPROPERTIES (
"column.xpath.provider_id"="/entity/link/@idType", --> not sure what to give here  
"column.xpath.paid"="/entity/link/@idType", --> not sure what to give here  
"column.xpath.pid"="/entity/link/@idType", --> not sure what to give here
"column.xpath.message_reason"="/entity/message/@reason"  
)
STORED AS
INPUTFORMAT 'com.ibm.spss.hive.serde2.xml.XmlInputFormat'
OUTPUTFORMAT 'org.apache.hadoop.hive.ql.io.IgnoreKeyTextOutputFormat'
LOCATION '/input/'
TBLPROPERTIES (
"xmlinput.start"="<entity>",
"xmlinput.end"="</entity>"
);

创建外部表xml\u测试
(
提供者id字符串，
付费字符串，
pid字符串，
消息\u原因字符串
)
行格式SERDE'com.ibm.spss.hive.serde2.xml.XmlSerDe'
具有serdeproperty(
“column.xpath.provider_id”=“/entity/link/@idType”，-->不确定在这里给出什么
“column.xpath.paid”=“/entity/link/@idType”，-->不确定在这里给出什么
“column.xpath.pid”=“/entity/link/@idType”，-->不确定在这里给出什么
“column.xpath.message_reason”=“/entity/message/@reason”
)
存储为
INPUTFORMAT'com.ibm.spss.hive.serde2.xml.XmlInputFormat'
OUTPUTFORMAT'org.apache.hadoop.hive.ql.io.IgnoreKeyTextOutputFormat'
位置'/input/'
TBLProperty(
“xmlinput.start”=”，
“xmlinput.end”=“”
);

有人能帮我吗？

按属性值选择元素

ie/entity/link[@idType='ProviderId']/text（）

创建外部表xml\u测试
(
提供者id字符串，
付费字符串，
pid字符串，
消息\u原因字符串
)
行格式SERDE'com.ibm.spss.hive.serde2.xml.XmlSerDe'
具有serdeproperty(
“column.xpath.provider_id”=“/entity/link[@idType='ProviderId']/text（）”，
“column.xpath.paid”=“/entity/link[@idType='paid']/text（）”，
“column.xpath.pid”=“/entity/link[@idType='pid']/text（）”，
“column.xpath.message_reason”=“/entity/message/@reason”
)
存储为
INPUTFORMAT'com.ibm.spss.hive.serde2.xml.XmlInputFormat'
OUTPUTFORMAT'org.apache.hadoop.hive.ql.io.IgnoreKeyTextOutputFormat'
位置'/input/'
TBLProperty(
“xmlinput.start”=”，
“xmlinput.end”=“”
);

与其定义三列，不如将一列定义为映射

        CREATE EXTERNAL TABLE xml_testing
        (
                 provider_id    String,
                 paid           String,
                 pid            String,
                 message_reason String
        )
        ROW FORMAT SERDE 'com.ibm.spss.hive.serde2.xml.XmlSerDe'
        WITH SERDEPROPERTIES (
        "column.xpath.provider_id"="/entity/link[@idType='ProviderId']/text()",  
        "column.xpath.paid"="/entity/link[@idType='PAID']/text()",   
        "column.xpath.pid"="/entity/link[@idType='PID']/text()", 
        "column.xpath.message_reason"="/entity/message/@reason"  
        )
        STORED AS
        INPUTFORMAT 'com.ibm.spss.hive.serde2.xml.XmlInputFormat'
        OUTPUTFORMAT 'org.apache.hadoop.hive.ql.io.IgnoreKeyTextOutputFormat'
        LOCATION '/input/'
        TBLPROPERTIES (
        "xmlinput.start"="<entity>",
        "xmlinput.end"="</entity>"
        );
