get an XML file with all attributes in a treeview

Nbl Bz

Hello ,
am new in C# programmation , then im working on an application for XML file.
I want to read an XML file on a treeview, i have a code but he dont get all attributes for the node parent .
this is my function
void BuildNode(XmlNode xmlNode, TreeNode node)
{

if (xmlNode.HasChildNodes)
{

foreach (XmlNode childNode in xmlNode.ChildNodes)
{

var treeNode = new TreeNode(childNode.Name);
node.Nodes.Add(treeNode);
BuildNode(childNode, treeNode);
}

}
else
{
node.Text = (xmlNode.OuterXml).Trim();
}
}
then for my button to browse xml file :
/* var doc = new XmlDocument();
doc.Load(textBox1.Text);
// doc.Load(@"e:\\Test.xml");

treeView1.Nodes.Clear();
var rootNode = new TreeNode(doc.DocumentElement.Name);
treeView1.Nodes.Add(rootNode);
BuildNode(doc.DocumentElement, rootNode);

treeView1.ExpandAll();

Accepted answer
Prepend the foreach with a null check:

if (xmlNode.Attributes != null)

foreach (...)

Hello JM Pollaerts ,
I try to do the other way of operation
Select some node in a treeView , then create an XML file with them ( or past them to an existing xml file )
Do u have a tuto or an exemple for that to start with ?

It ok like this :
foreach

(XmlAttribute attribute in xmlNode.Attributes)

                          {



if ( attribute.Name == "name" || attribute.Name == "title" || attribute.Name == "id" )

                              node.Text +=

string.Format(" {0}=\"{1}\"", attribute.Name , attribute.Value);

                          }

Big thanks for all

Like this :

if (xmlNode.Attributes != null)



foreach (XmlAttribute attribute in xmlNode.Attributes)
                       {
                             node.Text +=
string.Format(" {0}=\"{1}\"", attribute.Name == "id" && attribute.Name == "name", attribute.Value);

                          }

You can, just add a check within the attributes loop (.Name should match "id" or "name"), or specifically search for those two attributes, .Attributes is an associative array, but you need to add null checks.

No , but no preblem
Maybe , if we can choose what attribute we can show , it's possible to do it ?

for exemple

we show just id and name ?

With a lot of attributes perhaps they are just not visible. Do they show if you make your treeview wider?

am using the

if (xmlNode.Attributes != null)



foreach (XmlAttribute attribute in xmlNode.Attributes)

{

             node.Text +=

string.Format(" {0}=\"{1}\"", attribute.Name, attribute.Value);

                          }

before the

foreach (XmlNode childNode in xmlNode.ChildNodes)
{ }

then it's seems Ok ...

Just when i have a lot of attributes , i didn't had it all ( it's normal for a treeview ? )

I delete it ?

Is that perhaps because you use node.Text = xmlNode.OuterText ?

No
I have the same thing like my first code ... with the attributes and values of childs written 2 time.
something like this :

    // NO ATTRIBUTE
      // NO ATTRIBUTE
        id="121" x="2" y="0" // AS THE ATTRIBUTE VALUE
        id ="131" x="3" y="0"

Replace

        node.Text = (xmlNode.OuterXml).Trim();

With:

        node.Text = (xmlNode.OuterXml).Trim();
        foreach (XmlAttribute attribute in xmlNode.Attributes)
                node.Text += string.Format(" {0}=\"{1}\"", attribute.Name, attribute.Value);

Not sure what you've tried, but it should be something like this I think:

foreach (XmlAttribute attribute in xmlNode.Attributes)
```
{
```
var treeNode = new TreeNode(attribute.Name);
node.Nodes.Add(treeNode);
}

Every XmlNode has an Attributes property. You can loop through the values:

foreach (XmlAttribute attribute in xmlNode.Attributes)
```
    {         // code here     }
```
