[C# to XML]

Hi friends, I am new to csharp and XML :

fp=File.OpenText(server.mappath(".\\upload\\")+"te st.txt");
string info=fp.readtoend();
string[] arinfo =new string[4];

char splitter = {'|','^'};

arinfo =info.split(splitter);

for(int x=0;x<arinfo.length;x++)
{
response.write(arinfo[x]+"<br>");
a=arinfo[x];

xmltextwriter xwriter=new
xmltextwriter("C:/XML/Data.xml",system.text.encoding.UTF8);
xwriter.writestartdocument(true);
xwriter.writestartelement("login");
xwriter.writeelementstring("username",arinfo[0]);

What i am doing here is ,I am creating a new XML file Each TIME.

I dnt want like this , I have to insert into already created XML File ,In
that file i specified Each Element ,I want to insert values into inthat
element ,Without specifying (i.e username) each elements

Load XML into XmlDocument.
Modify some elements of XmlDocument.
Same it back to file.
