xml parsing - Noob question about Android and XmlParser -


i'm new android want read xml-file , write content listview

the xml parser must problem. hope little mistake in code.

orderxml2.xml

<?xml version="1.0"?> <order>    <item id="1">       <title>bitest1</title>       <group>g1</group>       <price>5.00</price>       <description>example</description>    </item>    <item id="2">       <title>test2</title>       <group>g1</group>       <price>2.00</price>       <description>example</description>    </item> </order>

the parser

public class order extends activity  {     private string[] lv_arr = {}; /** called when activity first created. */ @override         public void oncreate(bundle savedinstancestate)          {             super.oncreate(savedinstancestate);             setcontentview(r.layout.order);              try {                 arraylist<string> orderxmlarray = preparelistfromxml();                 lv_arr = (string[]) orderxmlarray.toarray(new string[0]);             } catch (xmlpullparserexception e) {                 // todo auto-generated catch block                 e.printstacktrace();             } catch (ioexception e) {                 // todo auto-generated catch block                 e.printstacktrace();             }              listview lv = (listview) findviewbyid(r.id.listvieworder1);              lv.setadapter(new arrayadapter<string>(order.this, android.r.layout.simple_list_item_1, lv_arr));         }          public arraylist<string> preparelistfromxml() throws xmlpullparserexception, ioexception         {             arraylist<string> orderitems = new arraylist<string>();             xmlresourceparser orderxml = getresources().getxml(r.xml.orderxml2);              orderxml.next();             int eventtype = orderxml.geteventtype();              while (eventtype != xmlresourceparser.end_document)              {                 if (eventtype == xmlresourceparser.start_document) {                     orderitems.add(orderxml.getattributevalue(null, "title"));                                               }                  else if(eventtype == xmlresourceparser.end_document) {                     orderitems.add(orderxml.getattributevalue(null, "title"));                           }                  try {                     eventtype = orderxml.next();                 } catch (xmlpullparserexception e) {                     // todo auto-generated catch block                     e.printstacktrace();                 } catch (ioexception e) {                     // todo auto-generated catch block                     e.printstacktrace();                 }             }             return orderitems;         } }

i think, can visit site http://www.ibm.com/developerworks/opensource/library/x-android/ . read section easier sax parsing, think solution presented there better have right know, less error prone.
