Question

我在TSQL中有XML，

Declare @xml XML = '<soap:Envelope xmlns:q1="urn:customization_2015_2.setup.webservices.netsuite.com" xmlns:urn1="urn:core_2015_2.platform.webservices.netsuite.com" xmlns:urn="urn:messages_2015_2.platform.webservices.netsuite.com" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
    <soap:Body xmlns:q1="urn:customization_2015_2.setup.webservices.netsuite.com" xmlns:urn1="urn:core_2015_2.platform.webservices.netsuite.com" xmlns:urn="urn:messages_2015_2.platform.webservices.netsuite.com" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
        <upsertList>
            <q1:record xmlns:q1="urn:customization_2015_2.setup.webservices.netsuite.com"  xsi:type="q1:CustomRecord" externalId="F95C35CF-950E-4756-8C33-43CA0C47FF45">
                <q1:recType internalId="12" type="customRecord"/>
                <q1:customFieldList xmlns="urn:core_2015_2.platform.webservices.netsuite.com">
                    <customField scriptId="custrecord_sps_content_package" xsi:type="SelectCustomFieldRef">
                        <value internalId="25"/>
                    </customField>
                    <customField scriptId="custrecord_sps_content_item" xsi:type="SelectCustomFieldRef">
                        <value internalId="1849"/>
                    </customField>
                    <customField scriptId="custrecord_sps_content_qty" xsi:type="LongCustomFieldRef">
                        <value>6.00</value>
                    </customField>
                </q1:customFieldList>
            </q1:record>
            <q1:record  xmlns:q1="urn:customization_2015_2.setup.webservices.netsuite.com"  externalId="D596F4DB-D7FE-409A-9D40-916FF88FB188">
                <q1:recType internalId="12" type="customRecord"/>
                <q1:customFieldList xmlns="urn:core_2015_2.platform.webservices.netsuite.com">
                    <customField scriptId="custrecord_sps_content_package" xsi:type="SelectCustomFieldRef">
                        <value internalId="24"/>
                    </customField>
                    <customField scriptId="custrecord_sps_content_item" xsi:type="SelectCustomFieldRef">
                        <value internalId="1902"/>
                    </customField>
                    <customField scriptId="custrecord_sps_content_qty" xsi:type="LongCustomFieldRef">
                        <value>2.00</value>
                    </customField>
                </q1:customFieldList>
            </q1:record>
        </upsertList>
    </soap:Body>
</soap:Envelope>'

现在，我想找到customField has attribute =＆gt;的xsi：type =＆＃34; LongCustomFieldRef＆＃34;然后将Value更新为Integer。意思是我想要整数：6而不是6.00

<customField scriptId="custrecord_sps_content_qty" xsi:type="LongCustomFieldRef">
                        <value>6</value>
                    </customField>

我不知道，为什么你需要这个。具有.00的数字将是一个没有任何麻烦的int。如果这主要是装饰性的，我不会碰这个...如果你需要这个（可能是由于非常严格的模式检查），你可以走这条路，但这不是微不足道的：

您可能知道，XML .modify()每次调用只能更新一个值。这是非常有限的。

如果您的结构始终相同，则可以使用CTE将其粉碎成碎片并从头开始重构XML。但这会导致你的命名空间出现新问题。

你可以试试这个：

- 你的Xml

DECLARE @xml XML = '<soap:Envelope xmlns:q1="urn:customization_2015_2.setup.webservices.netsuite.com"

</soap:Envelope>';

- 将其写入临时表

SELECT @xml AS TheXml INTO #tmpXml;

- 使用给定的xsi:type读取所有值，其中值包含dot
- 注意：您的customFieldList定义了一个新的默认命名空间！

WITH XMLNAMESPACES('http://schemas.xmlsoap.org/soap/envelope/' AS [soap]
                  ,'urn:customization_2015_2.setup.webservices.netsuite.com' AS q1
                  ,'http://www.w3.org/2001/XMLSchema-instance' as xsi
                  ,'urn:core_2015_2.platform.webservices.netsuite.com' AS innerDflt)
SELECT r.value('@externalId','uniqueidentifier') AS Record_ExternalId
      ,cf.value('@scriptId','nvarchar(max)') AS CustomField_ScriptId
      ,cf.value('(innerDflt:value/text())[1]','decimal(10,4)') AS OriginalValue
      ,CAST(cf.value('(innerDflt:value/text())[1]','decimal(10,4)') AS INT) AS CastedValue
INTO #tmpValues
FROM #tmpXml
CROSS APPLY TheXml.nodes('/soap:Envelope
                          /soap:Body
                          /upsertList
                          /q1:record') AS A(r)
CROSS APPLY A.r.nodes('q1:customFieldList
                      /innerDflt:customField[@xsi:type="LongCustomFieldRef" and innerDflt:value[contains(text()[1],".")]]') AS B(cf);

- 中级结果

SELECT * FROM #tmpXml 
SELECT * FROM #tmpValues;

- 使用CURSOR读取行，.modify()替换＆＃34;错误＆＃34;值。

DECLARE @rId NVARCHAR(MAX), @fId NVARCHAR(MAX), @v NVARCHAR(MAX);

DECLARE cur CURSOR FOR SELECT Record_ExternalId
                             ,CustomField_ScriptId
                             ,CAST(CastedValue AS NVARCHAR(MAX)) 
                       FROM #tmpValues;
OPEN cur;
FETCH NEXT FROM cur INTO @rId,@fId,@v;
WHILE @@FETCH_STATUS=0
BEGIN
    WITH XMLNAMESPACES(  'http://schemas.xmlsoap.org/soap/envelope/' AS [soap]

                        ,'http://www.w3.org/2001/XMLSchema-instance' as xsi
                        ,'urn:core_2015_2.platform.webservices.netsuite.com' AS innerDflt)
    UPDATE #tmpXml SET TheXml.modify('replace value of (/soap:Envelope
                                                        /soap:Body
                                                        /upsertList

    FETCH NEXT FROM cur INTO @rId,@fId,@v;
END
CLOSE cur;
DEALLOCATE cur;

- 重置@xml

SET @xml=(SELECT TheXml FROM #tmpXml);

- 最终结果

SELECT @xml;

TSQL XML将节点值转换为int
