      do you use DOM or XSLT to do the transformation?

          XSLT for the transformation.

                  just display out on the Label, Questions, Choices.
                  just display Selective Question only and not all Question under the element <question>. Or Choices <choice1>.

                  something like that.

                      how to read XML by using GetElementsByTa gName

                      the text of <question> you can get with //question/text(). same goes for <choiceX> (though I'd rename it to <choice no="X">, because you can then loop over <choice>). a special <question> you get with //question/text()[ancestor::modul e/@questionno. = 'X']

                          Could we see the code you're using to get choice1?

                              XmlNodeList Choice1 = doc.GetElements ByTagName("choi ce1");
                              foreach (XmlNode Choice in Choice1)
                              {
                              AnsLabel1.Text += Choice.ChildNod es[0].Value;
                              }

                              the code for choice and Question is similar.

                              please help.

                                  actually, this is DOM (Javascript maybe). XSLT is totally different. for XSLT I've given you (one possibility of) the XPath expressions you'll need for XSL. although I have no idea yet, how you will build it into HTML (a script?).
