In the end I used OmniXML with the following code.

uses
    OmniXML, OmniXMLUtils, OmniXMLXPath;

  ...

    function GetResultsURL(Filename: string): string;
    var
      FXMLDocument: IXMLDocument;
      XMLElementList: IXMLNodeList;
      XMLNode: IXMLNode;
      XMLElement: IXMLElement;
      i: integer;
    begin
      //Create and load the XML document
      FXMLDocument := CreateXMLDoc;
      FXMLDocument.Load(Filename);

      //We are looking for: 
      XMLElementList := FXMLDocument.GetElementsByTagName('Link');
      for i := 0 to Pred(XMLElementList.Length) do
        begin
          //Check each node and element
          XMLNode := XMLElementList.Item[i];
          XMLElement := XMLNode as IXMLElement;
          if XMLElement.GetAttribute('role') = 'output' then
            if Pos('failed', XMLNode.Text) > 0 then
                Result := XMLNode.Text;
        end;
    end;

The XML received looks like this ...
