You may use something like
XmlDocument xmldoc = new XmlDocument();
xmldoc.Load("mydata.xml");
label1.Text = xmldoc.SelectSingleNode("/Books/Text/Subject").FirstChild.Value;
label2.Text = xmldoc.SelectSingleNode("/Books/Text/Content").FirstChild.Value;
Provided you correctly fix your
XML
document (the bottom node should be
</Books>
)
