How do I make this XML file parser work in Unity

The parser seems to work differently to how I assumed.

This should work. $$anonymous$$aybe your file isn't being loaded properly because if you just load the xml string in directly it works fine.

              XmlDocument xmlDoc = new XmlDocument()
              {
                  InnerXml = @"
                   <mrow>
                     <apply>
                     <eq/>
                     <apply>
                         <plus/>
                         <apply>
                         <power/>
                         <ci>x</ci>
                         <cn>2</cn>
                         </apply>
                         <apply>
                         <times/>
                         <cn>4</cn>
                         <ci>x</ci>
                         </apply>
                         <cn>4</cn>
                     </apply>
                     <cn>0</cn>
                     </apply>
                     </mrow>
                 "
              };
 
              foreach (XmlNode node in xmlDoc.DocumentElement.ChildNodes)
              {
                  Debug.Log(node.InnerText); // Inside Unity
                  Console.WriteLine(node.InnerText); // Inside normal .NET app
              }
