Proper way to read an XML document

I have an XML file:

For some reason the code is all messed up even though it shows up right in the preview... Link: https://gyazo.com/d9a050f35a553dfe7718a7323e01bdb0

<u1 id="1"> <name>Damage over time</name> <desc>This is an upgrade Damage over time</desc> </u1> <u2 id="2"> <name>Double Damage</name> <desc>This is an upgrade Double damage</desc> </u2> <u3 id="3"> <name>Slow Regen</name> <desc>This is an upgrade Slow Regeneration</desc> </u3> <u4 id="4"> <name>Critical Chance</name> <desc>This is an upgrade Crit Chance</desc> </u4>

and after a lot of pain I am using this code to retrieve the information

         using (XmlReader xml = XmlReader.Create(Application.dataPath + Path.DirectorySeparatorChar + "Resources" + Path.DirectorySeparatorChar + "UpgradeDesc.xml")) {
             while (xml.Read()) {
                 if (xml.NodeType == XmlNodeType.Element) {
                     if (xml.GetAttribute("id") == upgrade.ToString()) {
                         using (XmlReader inner = xml.ReadSubtree()) {
 
                             bool foundDesc = false;
                             bool foundName = false;
                             string[] upgradeInfo = new string[3];
     
                             while (inner.Read()) {
                                 if (foundName) {
                                     upgradeInfo[0] = inner.Value;
                                 }
                                 if (foundDesc) {
                                     upgradeInfo[1] = inner.Value;
                                     upgradeInfo[2] = "info not from the XML here"; return upgradeInfo;
                                 }
                                 if (inner.LocalName == "name" && string.IsNullOrEmpty(upgradeInfo[0])) {
                                     foundName = true;
                                 }
                                 else {
                                     foundName = false;
                                 }
                                 if (inner.LocalName == "desc" && string.IsNullOrEmpty(upgradeInfo[1])) {
                                     foundDesc = true;
                                 }
                                 else {
                                     foundDesc = false;
                                 }
                             }
                         }
                     }
                 }
             }
             throw new System.Exception("No Upgrade of type " + (Upgrade.Upgrades)upgrade + " found!");
         }

While this works, I cant imagine this is the right way. How can I improve/optimize it ?

Thanks Majk-
