Get Child Nodes from an XML File
提问by Code-EZ
I have an XML File like below
我有一个像下面这样的 XML 文件
<Attachment>
<FileName>Perimeter SRS.docx</FileName>
<FileSize>15572</FileSize>
<ActivityName>ActivityNamePerimeter SRS.docx</ActivityName>
<UserAlias>JameelM</UserAlias>
<DocumentTransferId>7123eb83-d768-4a58-be46-0dfaf1297b97</DocumentTransferId>
<EngagementName>EAuditEngagementNameNew</EngagementName>
<Sender>[email protected]</Sender>
</Attachment>
I read these xml file like below
我阅读了这些 xml 文件，如下所示
var doc = new XmlDocument();
doc.Load(files);
foreach (XmlElement pointCoord in doc.SelectNodes("/Attachment"))
{
}
I need to get each child node value inside the Attachment node. How can i get these xml elements from the xml node list?
我需要在附件节点中获取每个子节点值。如何从 xml 节点列表中获取这些 xml 元素？

Your question is very unclear, but it lookslike it's as simple as:
你的问题很不清楚，但看起来很简单：
foreach (XmlNode node in doc.DocumentElement.ChildNodes)
{
}
After all, in the document you've shown us, the Attachmentisthe document element. No XPath is required.
毕竟，在您向我们展示的文档中，Attachment是文档元素。不需要 XPath。
As an aside, if you're using .NET 3.5 or higher, LINQ to XML is a muchnicer XML API than the old DOM (XmlDocumentetc) API.
顺便说一句，如果你使用.NET 3.5或更高版本，LINQ到XML是一种多比旧的DOM（更好的XML APIXmlDocument等）的API。

try this
尝试这个
var data = from item in doc.Descendants("Attachment")
select new
{
FileName= item.Element("FileName").Value,
FileSize= item.Element("FileSize").Value,
Sender= item.Element("Sender").Value
};
foreach (var p in data)
Console.WriteLine(p.ToString());

var doc = new XmlDocument();
doc.Load(files);
foreach (XmlElement pointCoord in doc.SelectNodes("/Attachment"))
{
if(pointCoord!=null)
{
var valueOfElement=pointCoord.InnerText;
}
}
if you want to run conditional logic against the element names (UserAlias, etc) then use the Name property of the XmlElement.
如果要针对元素名称（UserAlias 等）运行条件逻辑，请使用 XmlElement 的 Name 属性。
