XML Error: There are multiple root elements ,how to read XML string variable in asp.net c#?

Question

I am using visual studio 2012 asp.net c#. I am unable to read XML string variable "j". Please help. I want to read the string variable "j" and display the XML values on labels. Please let me know the proper codes. Thank you

WeatherAPI(lbldistrict.Text + "," + "India");
XmlDocument j = WeatherAPI(lbldistrict.Text + "," + "India");
var myXml = j.DocumentElement.InnerXml.ToString();

XmlDocument doc = new XmlDocument();
doc.LoadXml(myXml); //XML Error: There are multiple root elements

XmlTextReader reader = new XmlTextReader("j");
XmlNodeType type;
while (reader.Read())
{
    type = reader.NodeType;
    if (type == XmlNodeType.Element)
    {
        if (reader.Name == "temp_C")
        {
            reader.Read();
            lbltemp.Text = reader.Value;
        }
        if (reader.Name == "windspeedKmph")
        {
            reader.Read();
            lblwind.Text = reader.Value;
        }
        if (reader.Name == "weatherIconUrl")
        {
            reader.Read();
            ImgWeather.ImageUrl = reader.Value;
        }
        if (reader.Name == "weatherDesc")
        {
            reader.Read();
            lblDec.Text = reader.Value;
        } if (reader.Name == "tempMinC")
        {
            reader.Read();
            lblLow.Text = reader.Value;
        } if (reader.Name == "tempMaxC")
        {
            reader.Read();
            lblHigh.Text = reader.Value;
        } if (reader.Name == "humidity")
        {
            reader.Read();
            lblHumidity.Text = reader.Value;
        }
    }
}

I am getting XML file from web service. XML file looks like:

Answer 1

That InnerXml does not include the DocumentElement itself so it looks like you've got multiple roots in your XML document tree, and as a consequence, it's not an XML document. This might work:

var myXml = j.DocumentElement.InnerXml.ParentNode.ToString();

Or you could just treat the resulting XML as a set of element nodes.
