when programs goes through following code

documentbuilderfactory dbpub = documentbuilderfactory.newinstance();               documentbuilder db2 = dbpub.newdocumentbuilder();               url1 = "http://eutils.ncbi.nlm.nih.gov/entrez/eutils/esummary.fcgi?db=pubmed&id=23373820";               document docpmid = db2.parse(new url(url1).openstream());                                               nodelist nl = docpmid.getelementsbytagname("item");              if(nl !=null && nl.getlength() > 0)              {                (int y = 0; y < nl.getlength(); y++)                {                  element el = (org.w3c.dom.element) nl.item(y);                  if (el.hasattribute("name") && el.getattribute("name").equals("pubdate"))                  {                    string pubdate = el.getattribute("name");                    system.out.println("pubdate :"+pubdate);                  }                }              }

instead of getting pubdate :2013 mar pubdate :pubdate

probably overlooked...

you using same in if

if (el.hasattribute("name") && el.getattribute("name").equals("pubdate"))

and later same printing:

string pubdate = el.getattribute("name"); system.out.println("pubdate :"+pubdate);

which not want do, want read content, not attribute value...
