How Can I Use XMLDocument.SelectNodes in UWP

I am a beginner in programming UWP applications, but I know c#. My question is, how could I use selectnodes in a UWP applications since the definition doesn't exist... How would i work around this issue? Thanks.

Here is my code if needed

XmlDocument responseXML = new XmlDocument();
responseXML.LoadXml(response);

string innerText = responseXML.SelectNodes("//maininfo").Item(0).InnerText;
responseXML.LoadXml(innerText);

info1 = responseXML.GetElementsByTagName("upnp:info1").Item(0).InnerText;
info2 = responseXML.GetElementsByTagName("upnp:info2").Item(0).InnerText;
info3 = responseXML.GetElementsByTagName("dc:info3").Item(0).InnerText;
info4 = responseXML.GetElementsByTagName("dc:info4").Item(0).InnerText;

    The problem is that you have used wrong namespace(System.Xml) for XmlDocument. Please use Windows.Data.Xml.Dom namespace. For more you could refer to XmlDocument class official documentation. 

    using Windows.Data.Xml.Dom;

......

XmlDocument responseXML = new XmlDocument();
responseXML.LoadXml(response);
string innerText = responseXML.SelectNodes("//maininfo").Item(0).InnerText;

    Here is official XML DOM sample, please check.
