我有一些具有不同元素的 xml 文件。我想用 c# 或 PowerShell 编写一些代码来遍历每个元素并获取值。我希望它足够通用,以便我可以将它与其他 xml 文件一起使用。所有 xml 文件具有相同的格式,但元素的名称不同。
非常感谢你的帮助。
<root>
<list>
<FirstName>Abc</FirstName>
<LastName>LT</LastName>
<Occupatoin>Eng</Occupation>
<BirthDate></BirthDate>
...
</list>
</root>
----------------------
XML file 2
<root>
<Trainings>
<Java>Ab</Java>
<NET>b</NET>
<SQL>c</SQL>
<Powershell>d</Powershell>
...
</Trainings>
</root>
引入了另一个 xml,它将作为上述 xml 文件中元素迭代的基础。
根据下面每个元素的属性获取上面元素的值:
<root>
<Element Name="Firstname />
<Element Name="Lastname" />
<Element Name="Occupation" />
<Element Name="Java" />
<Element Name="Net" />
...
</root>
