Hi Wouter:
I went figured that i can delete the whole entry
for sid=781111 and then insert a new record of student
with a new sid.
i tried the following:
String xupd1 = "<xu:modifications version= \"1.0
\" " +
"xmlns:xu=
\"http://www.xmldb.org/xupdate\";> " +
"<xu:remove select=
\"//students/[EMAIL PROTECTED]'781111']\"> </xu:remove >"
+
"</xu:modifications >";
String xupd = "<xu:modifications version= \"1.0 \" "
+
"xmlns:xu=
\"http://www.xmldb.org/xupdate\";> " +
"<xu:append select= \"//students\">"+
"<student sid='781164'>"+
" <name>Laxma R Dendi</name>"+
" <degree>MS</degree>" +
" <major>Comuter Science</major>"+
"</student> </xu:append>"+
"</xu:modifications >";
this works.
but is there any other simple of doing it.
thanks for your reply.
sincerely
laxma
