this question has answer here:
it's hometask. don't understand want me , why doesn't work. fails on reader.next() . path right. here's code on java of staxparser:
public class staxparser { private dances dances; private dance currentdance; private dancer currentdancer; public static void main(string[] args) { staxparser staxparser = new staxparser(); staxparser.parse("dancegroupconcerts.xml"); } public dances getdances() { return dances; } public staxparser() { } public void parse (string xmlfilename){ try { xmlstreamreader reader = xmlinputfactory.newinstance().createxmlstreamreader(new stringreader(xmlfilename)); int tag; string tagname; string text = new string(); while (reader.hasnext()){ tag = reader.next(); switch (tag){ case xmlstreamreader.start_element: tagname = reader.getlocalname(); if (tagname == "dances") dances = new dances(); if (tagname.equals("dance")) currentdance = new dance(); if (tagname.equals("dancer")) currentdancer = new dancer(); break; case xmlstreamreader.characters: text = reader.gettext(); break; case xmlstreamreader.end_element: tagname = reader.getlocalname(); if (tagname.equals("dancer")) currentdance.getdancers().add(currentdancer); if (tagname.equals("dance")) dances.getdance().add(currentdance); if (tagname.equals("type")) currentdance.settype(text); if (tagname.equals("scene")) currentdance.setscene(text); if (tagname.equals("numberofdancers")) currentdance.setnumberofdancers(numberofdancers.fromvalue(text)); if (tagname.equals("music")) currentdance.setmusic(music.fromvalue(text)); if (tagname.equals("name")) currentdancer.setname(text); if (tagname.equals("danceteam")) currentdancer.setnameofdanceteam(text); if (tagname.equals("age")) currentdancer.setage(biginteger.valueof(integer.valueof(text))); if (tagname.equals("experience")) currentdancer.setexperience(biginteger.valueof(integer.valueof(text))); if (tagname.equals("number")) currentdance.setnumber(biginteger.valueof(integer.valueof(text))); break; } } } catch (xmlstreamexception e) { e.printstacktrace(); } } }
and xsd:

the problem lies xml-file. there (invisible) content before <?xml... causes parser fail. see question possible solution: content not allowed in prolog saxparserexception
to answer edit: possible won't see visible character in notepad++ - check following url possible solution: http://www.rgagnon.com/javadetails/java-handle-utf8-file-with-bom.html
