Hi,

I am trying to display data from this xml file:

C#

<?xml version="1.0" encoding="utf-8" ?>
<Prices>
  <PricePerItem>
    <Item Name="Milk, Low fat, 1Liter">11.2</Item>
    <Item Name="Butter">17</Item>
    <Item Name="Bread">12.2</Item>
    <Item Name="Cheese">15.5</Item>
  </PricePerItem>
  <PricePerKg>
    <Item Name="Apple, Jonagold">13.4</Item>
    <Item Name="Chicken">12.5</Item>
    <Item Name="Salad">9.6</Item>
    <Item Name="Fish, Salmon">14</Item>
  </PricePerKg>
</Prices>

I am trying to get out the values from each one.
I have a listbox and a button
Right now it displays like this
Milk,Low Fat, 1 Liter 11.21713.215.5
But i want it to display 11.2 for Milk because thats the value and not all the values from PricePerItem

this is my code for the button

C#

listBox1.Items.Clear();

            var xmlDoc = new XmlDocument();
            xmlDoc.Load(@"c:\users\morski\documents\visual studio 2013\Projects\Test\Test\prices.xml");

            XmlNodeList xnListPerItem = xmlDoc.SelectNodes("/Prices");


                foreach (XmlNode xn in xnListPerItem)
                {

                    string pricePerItem = xn["PricePerItem"].InnerText;

                    
                    //Adds pricePerItem
                    var pricePerItemList= new List<string>();

                    pricePerItemList.Add("Milk, Low fat, 1Liter" + pricePerItem);
                    pricePerItemList.Add("Butter" + pricePerItem);
                    pricePerItemList.Add("Bread" + pricePerItem);

                    foreach (var vItem in pricePerItemList)
                    {
                        
                        listBox1.Items.Add(vItem);
                        
                    }

"Display them..." — what "them"? What exactly do you want to show, how? Why? What's the problem?

I suspect that a big part of the problem is xmlDoc.SelectNodes("/Prices") .
Why isn't it xmlDoc.SelectNodes("/Prices/PricePerItem/Item") ?

xn["PricePerItem"].InnerText is obviously wrong.

And you shouldn't be hard-coding items into pricePerItemList, whatever that is.

Have a look at this:

System.Xml.XmlNodeList xnListPerItem = doc.SelectNodes("/Prices/PricePerItem/Item");

var pricePerItemList= new System.Collections.Generic.List<string>();

foreach (System.Xml.XmlNode xn in xnListPerItem)
{
    string temp = System.String.Format ( "{0} {1}" , xn.Attributes [ "Name" ].Value , xn.InnerText ) ;
    pricePerItemList.Add(temp);
}
