java - XmlPullParserException during parsing XML with XMLPullParser -

-

need resolve : trying parse xml -

<lungprotocol><configuration name="flus sitting">        <segment order="1" name="left upper anterior">     <segment order="2" name="left lower anterior">   </configuration> <configuration name="flus supine">       <segment order="1" name="left upper anterior">     <segment order="2" name="left lower anterior"> </configuration></lungprotocol>

with following function - 

public list<lungsegment> parse(inputstream is, string configuration) {          try {           xmlpullparserfactory factory = xmlpullparserfactory.newinstance();           factory.setnamespaceaware(true);           xmlpullparser  parser = factory.newpullparser();           segment = new lungsegment();         parser.setinput(is, null);           parser.require(xmlpullparser.start_tag, null, "configuration");         int eventtype = parser.geteventtype();         while (eventtype != xmlpullparser.end_document) {               string tagname = parser.getname();               switch (eventtype) {               case xmlpullparser.start_tag:                   if(("configuration").equalsignorecase(tagname) && parser.getattributevalue(null, "name").equalsignorecase(configuration)){                     eventtype = parser.next();                     //eventtype = parser.next();                     tagname = parser.getname();                     log.v("xmltag", "configuration = "+configuration);                 if (("segment").equalsignorecase(tagname)) {                       // create new instance of segment                         segment = new lungsegment();                       segment.setsegmentname(parser.getattributevalue(null, "name"));                       segment.setsegmentorder(integer.parseint(parser.getattributevalue(null, "order")));                 }                  }                 break;                case xmlpullparser.end_tag:                   if (tagname.equalsignorecase("segment")) {                       // add segment object list                       segments.add(segment);                   } else if (("configuration").equalsignorecase(tagname) && parser.getattributevalue(null, "name").equalsignorecase(configuration)) {                         return segments;                 }                   break;                }               eventtype = parser.next();           }        } catch (xmlpullparserexception e) {e.printstacktrace();}        catch (ioexception e) {e.printstacktrace();}        return segments;   }

where configuration name attribute of configuration tag. getting exception -

org.xmlpull.v1.xmlpullparserexception: expected: start_tag {null}configuration (position:start_document null@1:1 in java.io.inputstreamreader@42323800)

please me going wrong.

make these 2 changes in code:

  1. make xml valid. segment tags not ended. should be:<segment order="1" name="left upper anterior"/>

  2. remove line parser.require(xmlpullparser.start_tag, null, "configuration");

everything else looks fine. able run code well.
