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 具有属性 => xsi:type="LongCustomFieldRef" 然后将值更新为整数。意思是我想要 Integer: 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。一个带有 a 的数字.00可以毫无问题地转换为 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。这是相当有限的。

如果您的结构始终相同，则可以使用 aCTE将其分解成碎片并从头开始重新构建 XML。但这可能会给您的命名空间带来新的麻烦。

你可以试试这个：
