I am testing a SOAP service that has a single operation that returns a string containing an XML document. My server and client are implemented in PHP.
Here is the source for my client:
<?php
header('Content-Type: text/xml, charset=iso-8859-1');
header("Content-Disposition: inline");
try{
$sClient = new SoapClient('http://localhost/soap/test.wsdl');
$response = $sClient->getDocument();
echo($response);
} catch(SoapFault $e){
var_dump($e);
}
?>
And this is the XML returned by the SOAP service and echoed by the client:
<?xml version="1.0" encoding="iso-8859-1" ?>
<root>
<form formname="test">
<post postid="2000" userid="bbh" postdate="2011-09-14" posttime="11:03:32">
<item name="Item1" value="123" />
<item name="Item2" value="456" />
</post>
</form>
</root>
When I test the SOAP client in Firefox for mac, Firefox for Windows and Safari, the XML returned by the SOAP service is correctly displayed in these browsers. However, when I test it on IE7 (on Windows 2003 Server) I get a blank screen even though I see the XML if I do a view source on the page. When I test it on IE8 (on Windows 7), I get a popup box saying "Do you want to save this file or find a program online to load it?".
Does anyone have any idea why the XML is not being displayed correctly in IE7 and IE8?
UPDATE:
Here are the HTTP headers which I got from Live HTTP headers in Firefox:
