Instance application:

String strxmlfile = Server.MapPath ("Testxml.xml");
Xmlcontrol Xmltool = new Xmlcontrol (strxmlfile);

Data
Dglist.datasource = Xmltool.getdata ("book/authors[isbn=\" 0002\ "]");
Dglist.databind ();

Update element content
Xmltool.replace ("book/authors[isbn=\" 0002\ "]/content", "PPPPPPP");
Xmltool.save ();

Add a new node
Xmltool.insertnode ("book", "Author", "ISBN", "0004");
Xmltool.insertelement ("book/author[isbn=\" 0004\ "]", "Content", "aaaaaaaaa");
Xmltool.insertelement ("book/author[isbn=\" 0004\ "]", "Title", "Sex", "Man", "IIIIIIII");
Xmltool.save ();

Remove all of the contents and attributes of a specified node
Xmltool.delete ("book/author[isbn=\" 0004\ "]");
Xmltool.save ();

Delete a child node of a specified node
Xmltool.delete ("book/authors[isbn=\" 0003\ "]");
Xmltool.save ();
