c# reading XML node quickest way...

**Meganutter** · Mar 4 '09, 07:55 AM

I just started out with XML files and found the XmlNodeList function quite usable.

heres a snippet of my code, i hope it makes sense to you

Code:

//Load an XML File
                XmlDocument xdXml = new XmlDocument();
                xdXml.Load("Index.xml");

                //Make a nodelist
                XmlNodeList xnNodes = xdXml.SelectNodes("/Tools/Download");

                //Walk through the list
                foreach (XmlNode node in xnNodes)
                {
                    if (node.FirstChild.InnerText == ddlTools.Text)
                    {
                        //Get all the child nodes
                        XmlNodeList childNodes = node.ChildNodes;

                        //And walk through them
                        foreach (XmlNode child in childNodes)
                        {
                            //Check which node we have now
                            switch (child.Name)
                            {
                                case "Name":
                                    txtName.Text = child.InnerText;
                                    break;
                                case "Version":
                                    txtVersion.Text = child.InnerText;
                                    break;
                                case "Category":
                                    txtCategory.Text = child.InnerText;
                                    break;
                                case "Description":
                                    txtDescription.Text = child.InnerText;
                                    break;
                            }
                        }
                        childNodes = null;
                        break;
                    }
                }

                //Clean up
                xdXml = null;
                xnNodes = null;

I am not too experienced and try understanding this code but I am hanging with (Line 11):

if (node.FirstChil d.InnerText == ddlTools.Text)

From where comes this ddlTools??
Could please someone help me and give an explanation?

**Meganutter** · Jun 4 '09, 01:54 PM

ddlTools is a dropdown list in the application, the parts that matter are the foreach loops mostly.

basically it checks wether the XML value is the same as the selected value of that dropdown menu.
