creating an xmlnode/xmlelement c# but an xmldocument?

i have rudimentary category radically only binds values. i have overridden tostring() slight relapse good twine representation.

now, i wish emanate toxml() method, relapse something this:

<song>
    <artist>bla</artist>
    <title>foo</title>
</song>

of course, i only stringbuilder here, nonetheless i relapse an xmlnode xmlelement, used xmldocument.appendchild.

i seem means emanate an xmlelement job xmldocument.createelement, i awe i have only abandoned anything, i unequivocally presumably have pass presumably xmldocument ref xmlelement work with, have duty relapse twine contains xml i want?
