yes it is true to some extent becuase we can still modify all the attributes in non leaf nodes. for example to change all the "sid"s i am using the following working code String xupd = "<xu:modifications version= \"1.0 \" " + "xmlns:xu= \"http://www.xmldb.org/xupdate\";> " + "<xu:update select= \"//students/student/@sid\">"+ "781164</xu:update>"+ "</xu:modifications >"; with the above code all the sid's are changed to 781164. my question is when we can modify all the atributes, why not one specific attribute...?
