java dom parser only gets the first entity -


this code returs 1 "question " tag's element have 9 question element inside xml file.what wrong thing in here?do need loop.because when checked loop, loops 1 time.what problem?i figure out.

here xml:

<results>   <question>     <eno>3</eno>     <qno>1</qno>     <qtext>the battle of gettysburg fought during war?</qtext>     <correctanswer>c</correctanswer>   </question>   <question>     <eno>3</eno>     <qno>2</qno>     <qtext>neil armstrong , buzz aldrin walked how many  minutes on moon in 1696?</qtext>     <correctanswer>b</correctanswer>   </question>  </results>

my source code:

nodelist listofquestions = doc.getelementsbytagname("question"); for(int s=0; s<listofquestions.getlength(); s++)         {             system.out.println(listofquestions.getlength());             node firstquestionnode = listofquestions.item(0);             if(firstquestionnode.getnodetype() == node.element_node){                 element firstqelement = (element)firstquestionnode;                  nodelist enolist = firstqelement.getelementsbytagname("eno");                 element enoelement =(element)enolist.item(s);                 nodelist enoslist = enoelement.getchildnodes();                 string eno=((node)enoslist.item(s)).getnodevalue().trim();                 system.out.println(eno);                  nodelist qnolist = firstqelement.getelementsbytagname("qno");                 element qnoelement =(element)qnolist.item(s);                 nodelist qnoslist = qnoelement.getchildnodes();                 string qno= ((node)qnoslist.item(s)).getnodevalue().trim();                 system.out.println(qno);                  nodelist qtextlist = firstqelement.getelementsbytagname("qtext");                 element qtextelement =(element)qtextlist.item(s);                 nodelist qtextslist = qtextelement.getchildnodes();                 string qtext= ((node)qtextslist.item(s)).getnodevalue().trim();                 system.out.println(qtext);                  nodelist correctanswerlist = firstqelement.getelementsbytagname("correctanswer");                 element correctanswerelement =(element)correctanswerlist.item(s);                 nodelist correctanswerelementlist = correctanswerelement.getchildnodes();                 string correctanswer= ((node)correctanswerelementlist.item(s)).getnodevalue().trim();                 system.out.println(correctanswer);                  int i=st.executeupdate("insert question(eno,qno,qtext,correctanswer) values('"+eno+"','"+qno+"','"+qtext+"','"+correctanswer+"')");                 system.out.println("s is"+s);             }         }

you have hardcoded

node firstquestionnode = listofquestions.item(0);                                              ^^^

i think meant use variable s there... or maybe not, it's hard tell you're trying do. regardless, there no other references listofquestions , never retrieve node except first one.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
