我有一堆(平面)
XML文件,例如：
<?xml version="1.0" encoding="UTF-8"?>
<SomeName>
<UID>
ID123
</UID>
<Node1>
DataA
</Node1>
<Node2>
DataB
</Node2>
<Node3>
DataC
</Node3>
<AnotherNode1>
DataD
</AnotherNode1>
<AnotherNode2>
DataE
</AnotherNode2>
<AnotherNode3>
DataF
</AnotherNode3>
<SingleNode>
DataG
</SingleNode>
</SomeName>
现在我的实际XML文件有太多的节点,所以它们不能导入到单个表中(由于255列限制),所以我需要将数据拆分成多个表.我已经手动创建了表,所以现在所有访问都必须将Node名称与每个表中的列匹配并复制数据.
它只对一个名为“SomeName”的表执行此操作,但保持所有其他表不变.
我不确定如何访问将我的XML文件正确导入到所有表中.我还尝试在每个表中创建UID字段并链接它们(因为UID对每个XML数据集都是唯一的),但这也使得访问权限不受影响.
我试图找到关于这个问题的任何信息,但迄今为止一无所获.
我非常感谢任何帮助或指示.
由于您需要超过255个字段,因此您必须使用代码执行此操作.您可以将XML加载到MSXML2.DOMDocument中,收集节点值的子集,构建INSERT语句并执行它.
原文链接：https://www.f2er.com/xml/292745.html这是我针对您的示例数据测试的过程.这很难看,但它确实有效.修改strTagList,strFieldList,strTable和cintNumTables后取消注释CurrentDb.Execute行并查看INSERT语句.如果要加载的表超过2个,请添加其他Case块.
