var infowindow;   var map;    function initialize() {     var mylatlng = new google.maps.latlng(38.822590,24.653320);     var myoptions = {       zoom: 5,       center: mylatlng,       maptypeid: google.maps.maptypeid.roadmap     }     map = new google.maps.map(document.getelementbyid("map_canvas"), myoptions);     downloadurl("moredata.xml", function(data) {       var items = data.documentelement.getelementsbytagname("item");       (var = 0; < items.length; i++) {         var description = items[i].getelementsbytagname("description")[0].childnodes[0].nodevalue;         var humidity    = items[i].getelementsbytagname("outsidehumidity")[0].childnodes[0].nodevalue;         var temp        = items[i].getelementsbytagname("temp")[0].childnodes[0].nodevalue;         var latlng = new google.maps.latlng(parsefloat(items[i].getelementsbytagname("lat")[0].childnodes[0].nodevalue),                                     parsefloat(items[i].getelementsbytagname("lng")[0].childnodes[0].nodevalue));          if ( temp > "1 °c" ) {           alert(temp);           var marker = createmarker( description,latlng );           }            if (humidity > "97 %") {           alert(humidity);           var marker = createmarker( description,latlng );           }         }      });   }    var iconbase = 'weather_icons/';         var icons = {           ilios: {             icon: iconbase + 'ilios.png'           },           pagetos: {             icon: iconbase + 'pagetos2.png'           },           omixli: {           icon: iconbase + 'omixli.png'           }         };    function createmarker(description, latlng) {     var marker = new google.maps.marker({     position: latlng,     map: map,     icon: icons['pagetos'].icon     });      //var marker1 = new google.maps.marker({     //position: latlng,     //map: map,     //icon: icons['omixli'].icon     //});      google.maps.event.addlistener(marker, "click", function() {       if (infowindow) infowindow.close();       infowindow = new google.maps.infowindow({content: description});       infowindow.open(map, marker);     });     return marker;   } 

here's moredata.xml

<item> <description>thesaloniki</description> <temp>10 °c</temp> <outsidehumidity>98 %</outsidehumidity> <lat>40.422726139672626</lat> <lng>22.93392777442932</lng> </item> <item> <description>giannena</description> <temp>14 °c</temp> <outsidehumidity>90 %</outsidehumidity> <lat>39.62209843837158</lat> <lng>20.89027225971222</lng> </item> <item> <description>atiki</description> <temp>15 °c</temp> <outsidehumidity>65 %</outsidehumidity> <lat>38.08469095792561</lat> <lng>23.680233657360077</lng> </item> 

after lot of searching , found solution!
have create many createmarker functions images are!i'm gonna insert correct code , hope in future you! here are..

var infowindow;   var map;    function initialize() {     var mylatlng = new google.maps.latlng(38.822590,24.653320);     var myoptions = {       zoom: 5,       center: mylatlng,       maptypeid: google.maps.maptypeid.roadmap     }     map = new google.maps.map(document.getelementbyid("map_canvas"), myoptions);     downloadurl("moredata.xml", function(data) {       var items = data.documentelement.getelementsbytagname("item");       (var = 0; < items.length; i++) {         var description = items[i].getelementsbytagname("description")[0].childnodes[0].nodevalue;         var humidity    = items[i].getelementsbytagname("outsidehumidity")[0].childnodes[0].nodevalue;         var temp        = items[i].getelementsbytagname("temp")[0].childnodes[0].nodevalue;         var title       = items[i].getelementsbytagname("title")[0].childnodes[0].nodevalue;         var latlng = new google.maps.latlng(parsefloat(items[i].getelementsbytagname("lat")[0].childnodes[0].nodevalue),                                     parsefloat(items[i].getelementsbytagname("lng")[0].childnodes[0].nodevalue));          if ( temp > "38 °c" ) {           alert(temp);           var marker = createmarker2( description,latlng,ilios );           }            if ( temp < "1 °c" ) {           alert(temp);           var marker = createmarker( description,latlng,cold );           }            if ( humidity > "97%" ) {           alert(windspeed);           var marker = createmarker1( description,latlng,omixli );           }         }      });   }    var cold  = 'weather_icons/pagetos2.png';   var omixli = 'weather_icons/omixli.gif';   var ilios = 'weather_icons/ilios.png';    function createmarker( description,latlng,cold ) {     var marker = new google.maps.marker({     position: latlng,     map: map,     icon: cold     });      google.maps.event.addlistener(marker, "click", function() {       if (infowindow) infowindow.close();       infowindow = new google.maps.infowindow({       content: description       });       infowindow.open(map, marker);     });     return marker;   }    function createmarker1( description,latlng,omixli ) {     var marker1 = new google.maps.marker({     position: latlng,     map: map,     icon: omixli     });      google.maps.event.addlistener(marker1, "click", function() {       if (infowindow) infowindow.close();       infowindow = new google.maps.infowindow({       content: description       });       infowindow.open(map, marker1);     });     return marker1;   } function createmarker2( description,latlng,ilios) {     var marker2 = new google.maps.marker({     position: latlng,     map: map,     icon: ilios     });      google.maps.event.addlistener(marker2, "click", function() {       if (infowindow) infowindow.close();       infowindow = new google.maps.infowindow({       content: description       });       infowindow.open(map, marker2);     });     return marker2;   } 

endly , wanna lot commented , gave me suggestions!
