现在我想要从这个 xml 获取所有电子邮件地址并插入到另一个 table。此 xml 包含 3 个电子邮件地址，我希望获取直到 n 个电子邮件地址，一个 xml 文件将包含

Answer 1

如链接答案所示，您可以使用 XMLTable 提取多个值；但您至少需要定义您使用的名称空间，并正确构造 XPath。因此，要仅获取电子邮件地址，您可以执行以下操作：

select x.emailaddress
from xml_message m
cross apply xmltable (
  xmlnamespaces (
      'http://schemas.xmlsoap.org/soap/envelope/' as "soapenv",
      'http://gateway.consumerhub.commercial.volvocars.net/oagis' as "oag",
      'http://www.openapplications.org/oagis' as "oag1",
      'http://www.ford.com/oagis' as "ns3"
  ),
  'soapenv:Envelope/soapenv:Body/oag:UpdateConsumerAndOpportunityData_v1/oag:DataArea/oag:Consumer/oag:ConsumerDetails/oag:EmailAddress'
  passing xmltype(m.xml_clob)
  columns
    EmailAddress varchar2(64) path '.'
) x;

EMAILADDRESS
ticc888@yahoo.com
ahng2@hotmail.com
jsmith@gmail.com

XPath 不引用 oag1 或 ns3，但包含它们也无妨，您可能需要它们从同一个 XML 文档中提取其他信息。

这还可以让您一次提取多个值；或者基于属性进行过滤 - 例如，您可能只想包含属性 Active 设置为 true 的电子邮件地址，您可以通过将该条件添加到 XPath 来实现：

  'soapenv:Envelope/soapenv:Body/oag:UpdateConsumerAndOpportunityData_v1/oag:DataArea/oag:Consumer/oag:ConsumerDetails/oag:EmailAddress[@Active="true"]'
