working with xml

Few days ago, I got a task to provide a Chart with with the chart highlights which is a brief description of the chart value. To get the chart is easier then to get the values of the chart. '
There are 3 links to get the values from. From the first xml file, I manage to find a way to get the value based on the node name.

Get nodes (and values) after selected node

Dictionary dict = new Dictionary();

private void getElement(string URLString, string tagName)

{

XmlTextReader reader = new XmlTextReader(URLString);

reader.WhitespaceHandling = WhitespaceHandling.None;

XmlDocument doc = new XmlDocument();

doc.Load(reader);

if ((doc != null))

{

try

{

int i = 0;

XmlNodeList elemList = doc.GetElementsByTagName(tagName);

foreach (XmlNode elem in elemList)

{

for (int j = 0; j < elem.ChildNodes.Count; j++)

{

callChildNode(elem.ChildNodes[j]);

}

i++;

}

}

catch (Exception ex)

{

// exception

throw ex;

}

}

}

private void callChildNode(XmlNode node)

{

if (node.Name != "#text")

if (node.ChildNodes.Count == 1 )

dict.Add(node.Name, node.InnerText);

for (int j = 0; j < node.ChildNodes.Count; j++)

{

callChildNode(node.ChildNodes[j]);

}

}

From the line above, all the nodes with value after the tag that we defined will be listed inside the dictionary. That is for the case if you have a different xml tag that you wish to get the node value from (even if the node inside is the same with the node from the other tag).

Get node value based on another node's value

After the first XML, I thought everything is solved, but then when I saw the second XML, it was totally different from the first xml. Dang!! so I have to find a way to get value of a node based on another node's value.

I searched in the internet and got a sample of code from the link below:

http://stackoverflow.com/questions/6203666/xpath-select-a-node-based-on-another-node

Below are the code

var doc = new XmlDocument();
doc.LoadXml(xmlString);
XmlElement element = (XmlElement)doc.SelectSingleNode("Items/Item[Code='MyCode']/Value");
Console.WriteLine(element.InnerText);

Hope this two code will be useful..
