I have what seems to be the exact same problem as Bern, but it isn't resolved by Davide's advice.
I've followed this demo: http://code.google.com/apis/maps/articles/phpsqlajax_v3.html My attempt here: http://pr107m.psur.utk.edu/~lilia/campusmap/help/ I am trying to get at the contents of the "department" element in the XML from genxml-building-depts.php<http://pr107m.psur.utk.edu/%7Elilia/campusmap/help/genxml-buildings-depts.php>(php shown below): // building SQL $Bquery = "SELECT building_name, building_id, building_code, building_infoLat, building_infoLng, building_type FROM building ORDER BY building_name"; $Bresult = mysql_query($Bquery); if (!$Bresult) { die('Invalid Bquery: ' . mysql_error()); } //fetch building data while ($Brow = mysql_fetch_array($Bresult, MYSQL_ASSOC)) { //for each building foreach ($Brow as $key => $value) { //echo out building element & building name if ($key=="building_name") { // ADD TO XML DOCUMENT NODE $item = $dom->createElement("building"); $root->appendChild($item); $item->setAttribute("building_name",parseToXML($value)); //create text node //$Btext = $dom->createTextNode(parseToXML($value)); //$item->appendChild($Btext); } //give building element attributes if ($key=="building_id") { $item->setAttribute("building_id",$value); } if ($key=="building_code") { $item->setAttribute("building_code",$value); } if ($key=="building_infoLat") { $item->setAttribute("building_infoLat",$value); } if ($key=="building_infoLng") { $item->setAttribute("building_infoLng",$value); } if ($key=="building_type") { $item->setAttribute("building_type",$value); //if you're echoing the building_type, grab these depts while you're at it $Dquery = 'SELECT * FROM departments WHERE departments_buildingID = '.$Brow['building_id']; $Dresult = mysql_query($Dquery); if (!$Dresult) { die('Invalid Dquery: ' . mysql_error()); } //fetch dept array while ($Drow = mysql_fetch_array($Dresult, MYSQL_ASSOC)) { //echo out department info foreach ($Drow as $key2 => $value2) { //echo out department element & department name if ($key2=="departments_name") { // add child node $dept = $dom->createElement("department"); $item->appendChild($dept); //create text node $Dtext = $dom->createTextNode($value2); $dept->appendChild($Dtext); } //give department element attributes if ($key2=="departments_buildingID") { $dept->setAttribute("departments_buildingID",$value2); } if ($key2=="departments_room") { $dept->setAttribute("departments_room",$value2); } if ($key2=="departments_url") { $dept->setAttribute("departments_url",$value2); } if ($key2=="departments_phone") { $dept->setAttribute("departments_phone",$value2); } if ($key2=="departments_email") { $dept->setAttribute("departments_email",$value2); } } } } } } echo $dom->saveXML(); ?> Sample of XML: <building building_name="Aconda Court " building_id="3" building_code="AC" building_infoLat="35.9571980000" building_infoLng="-83.9299680000" building_type="building"> <department departments_buildingID="3" departments_room="104" departments_url="http://www.math.utk.edu/"; departments_phone="(865) 974-2461" departments_email="[email protected]">Mathematics</department> </building> Like Bern, I'm declaring a variable that attempts to get the first child of "building" and I had it structured the same: var deptName = markers[i].childNodes[0].nodeValue; But Firebug says markers[i].childNodes[0] is undefined. This makes sense to me because when I uncomment these lines: //$Btext = $dom->createTextNode(parseToXML($value)); //$item->appendChild($Btext); from genxml-buildings-depts.php<http://pr107m.psur.utk.edu/%7Elilia/campusmap/help/genxml-buildings-depts.php>, markers[i].childNodes[0].nodeValue spits out the building name. But I don't need that, so I leave them commented. Then, I adjusted my code according to Davide's advice: var deptName = markers[i].childNodes[1].textContent; But again, Firebug says that markers[i].childNodes[1] is undefined. I've tried using debuggers in other browsers, but they haven't been able to provide any more information to help me troubleshoot. I tried adjusting my code to match the example that Bern uses (it's still commented out in http://pr107m.psur.utk.edu/~lilia/campusmap/help/), but I get the same message in FireBug: markers[i].childNodes[1] is undefined. To be honest, I have no clue what I'm doing wrong. From what I've read and the instructions I've followed, I think I'm doing it right? Any, any help would be very much appreciated. I apologize in advance if my explanation is convoluted, I'm just trying to provide a thorough description of what I've tried. -- You received this message because you are subscribed to the Google Groups "Google Maps JavaScript API v3" group.
