从XML文件中获取子节点

Question

I have an XML File like below

<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>JameelM@orioninc.com</Sender>
</Attachment>

I read these xml file like below

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?

Answer 1

I need to get each child node value inside the Attachment node.

Your question is very unclear, but it looks like it's as simple as:

foreach (XmlNode node in doc.DocumentElement.ChildNodes)
{
}

After all, in the document you've shown us, the Attachment is the document element. No XPath is required.

As an aside, if you're using .NET 3.5 or higher, LINQ to XML is a much nicer XML API than the old DOM ( XmlDocument etc) API.

try this

 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());

Answer 3

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.
