[SOLVED] Cant read XML data

[garethhall]

Hello Guys I have page I am working on but my xml object is null? well it's null when I do an alert? Can you guys see something work?

 

Javascript

var xmlHttp
function getMemDetail(){
xmlHttp=GetXmlHttpObject()
if(xmlHttp==null){
	alert("Browser does not support HTTP Request");
	return;
}
var qstr;
qstr = "memID="+document.getElementById('members').value;
xmlHttp.onreadystatechange = returnDetails;
xmlHttp.open("POST","ajax/getMemberDetails.php?",true);
xmlHttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlHttp.send(qstr);
}
function returnDetails(){ 
if(xmlHttp.readyState==4 ){ 
	//alert(xmlHttp.responseText);
	//xmlDoc = xmlHttp.responseXML;
	alert(xmlHttp.responseXML);    //WHY IS THIS NULL
		document.getElementById("toName").innerHTML = xmlDoc.getElementsByTagName("memFirstName")[0].childNodes[0].nodeValue;
}
} 

function GetXmlHttpObject(){
var xmlHttp=null;
try{
	// Firefox, Opera 8.0+, Safari
	xmlHttp=new XMLHttpRequest();
}catch (e){
	// Internet Explorer
	try{
		xmlHttp=new ActiveXObject("Msxml2.XMLHTTP");
	}catch (e){
		xmlHttp=new ActiveXObject("Microsoft.XMLHTTP");
	}
}
return xmlHttp;}

 

PHP

<?php
include("../../includes/cmsConfig.php");
include("../../includes/sharedFunctions.php");
auth();

$sql = "SELECT * FROM members WHERE memID = ".checkVars($_POST['memID']);
$rs = mysql_query($sql ,$admin);
$rw = mysql_fetch_assoc($rs);


echo '<?xml version="1.0" encoding="ISO-8859-1"?>';
echo '<member>';
echo '<memName>'.$rw['memName'].'</memName>';
echo '<memFirstName>'.$rw['memFirstName'].'</memFirstName>';
echo '<memLastName>'.$rw['memLastName'].'</memLastName>';
//	echo '<memAddress>'..'</memAddress>';
echo '</member>';
?>

You might want to check the output of your XML, the line

 

echo <?xml version="1.0" encoding="ISO-8859-1"?>';

 

looks slightly wrong. Make sure your <? are being printed correctly. You also appear to be missing a ' from the start of the echo

Sorry typo ' is present but the same fault.

[garethhall]

Anyone please?

Have you tried the echo statement like this

 

echo "<?xml version=\"1.0\" encoding=\"ISO-8859-1\"?>
<member>
<memName>".$rw['memName']."</memName>
<memFirstName>".$rw['memFirstName']."</memFirstName>
<memLastName>".$rw['memLastName']."</memLastName>
</member>";

 

iv tested this in IE and it comes up as xml

Hi when I do

alert(xmlHttp.responseText) this is my result

<?xml version="1.0" encoding="UTF-8"?>
<member>
<memName>starwars</memName>
<memFirstName>Luke</memFirstName>
<memLastName>Hall</memLastName>
</member>

 

When I alert(xmlHttp.responseXML) I get null?

 

I have since the last post change my php page and the code is like this now.

<?php
include("../../includes/cmsConfig.php");
include("../../includes/sharedFunctions.php");
auth();

$sql = "SELECT * FROM members WHERE memID = ".checkVars($_POST['memID']);
$rs = mysql_query($sql ,$admin);
$rw = mysql_fetch_assoc($rs);

$xmltext = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<member></member>";
$xmlobj = simplexml_load_string($xmltext);

$xmlobj->addChild("memName", $rw['memName']);
$xmlobj->addChild("memFirstName", $rw['memFirstName']);
$xmlobj->addChild("memLastName", $rw['memLastName']);

print header("Content-type: text/plain") . $xmlobj->asXML();
?>

Found the problem needed to set the content type to text/xml
