Sql 如何从多个同名XML节点返回行？

以下XML在节点“attachDocument”下有多个节点。下面的SQL查询只返回“attachDocument”的第一个节点的行，而不是第二个节点的行

是否有人可以帮助从“attachDocument”的两个节点返回行

先谢谢你

SQL查询。。。
;使用XMLNAMESPACES（'http://xyz.in/twa/cmm/decl/v2"如你所愿)
挑选
response.value（“（//ur:attachDocument/ur:category）[1]”，“'varchar（50）”作为类别，
response.value（“（//ur:attachDocument/ur:mimeCode）[1]”，“'varchar（50）”作为mimeCode，
value（“（//ur:attachDocument/ur:URI）[1]”，'varchar（50）”作为URI，
response.value（“（//ur:attachDocument/ur:filename）[1]”，'varchar（50）”作为[filename]，
response.value（“（//ur:status/ur:agency）[1]”，“'varchar（100）”作为ResponseAgency，
response.value（“（//ur:response/ur:issueDate）[1]”，“'varchar（100）”作为responseIsueDateTime，
response.value（“（//ur:response/ur:additionalInformationICN）[1]”，“'varchar（100）”作为ResponseClearanceInstructions
从@sqlxml.nodes（'//ur:response'）作为T（response）

请尝试以下解决方案

值得注意的是：

• 正确声明默认名称空间可以全面简化XPath表达式。默认命名空间不需要前缀
• 最好不要在XPath表达式中使用

  /

  。它会导致遍历整个XML。完全限定的路径对性能更好
• 将text（）添加到XML元素的XPath表达式中可以提高性能

这是完美的作品。。。谢谢伊扎克。。非常感谢…@SQLHoncho，很高兴听到提议的解决方案对您有效。请向上投票建议：@SQLHoncho，请在LinkedIn上与我联系。请参考以上XML脚本。。。节点“additionalInformationICN”下存在相同的节点“AttachDocument”，如下所示。。。正在努力添加到上面的SQL脚本以返回它。有人能帮忙吗？请参考随附的XYZ，了解ABC文本/普通1511b476-a2ef-6ae5-a54c-0a5dc14759b2 DEF_B2019_199_xml.txt的说明
