Making a dynamic RSS feed from external XML file

I am trying to generate an RSS feed for a streamate whitelabel site. The network support have provided me with the bare minimum information on how to generate anything.

This is all they have provided to generate info about live performers:

"This query is used to retrieve information about performers. You will receive the information packaged into an XML document. Please send your XML request by HTTP POST to: http://affliate.streamate.com/??????/SMLResult.xml Be sure to send a “Content-type: text/xml” header as part of the HTTP request. You may replace streamate.com with a branded domain, if one is available to you, to have URLs returned with that same branded domain instead of streamate.com"

So, I have managed to find out how to pull live info from their XML feed into a php page, by searching for a snippet of code, but this is not an RSS feed that I can utilise (to feed into social networks, etc).

If anyone can please give me some pointers on how to utilise their XML file into an RSS feed which links to my own whitelabe domain (as they have half instructed above).

Below is the code I have found and used to generate the live info on a php page (I just wish it was an RSS feed).

<?php
$curlData = '<?xml version="1.0" encoding="UTF-8"?>
    <SMLQuery>
    <Options MaxResults="20"/>
    <AvailablePerformers Exact="false" PageNum="1" CountTotalResults="true">
    <Include>

    <Headline/>
    <Descriptions></Descriptions>

    <Age/>
    <Gender/>
    <Media>biopic</Media>

    <PerformanceSort/>

    <Constraints> <StreamType>live,recorded,offline</StreamType>

    </AvailablePerformers>
    </SMLQuery>';

$url='http://affiliate.streamate.com/????/SMLResult.xml';
$curl = curl_init();

curl_setopt ($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl,CURLOPT_TIMEOUT,120);
curl_setopt($curl,CURLOPT_HTTPHEADER,array ('Content-Type: application/xml; charset=utf-8',));
curl_setopt ($curl, CURLOPT_POST, 1);
curl_setopt ($curl, CURLOPT_POSTFIELDS, $curlData);

$result = curl_exec($curl);
curl_close ($curl);

$xml = simplexml_load_string ($result);
// $json = json_encode($xml);
// $array = json_decode($json,TRUE);

print_r ($result);
?>

    echo "<p>";
    echo "<br />";
}
?>

</body>
</html>

and here is one of the example snippets that the affiliate network provided, which I can see is part of the above code I found:

XML Request Structure Example, Real World Generic

<?xml version="1.0" encoding="UTF-8"?>
<SMLQuery>
<Options MaxResults="50" />
<AvailablePerformers QueryId=”MyGenericQuery”>
<Include>
<Descriptions />
<Media>staticbiopic</Media>
</Include>
<Constraints>
<PublicProfile />
<StreamType>live</StreamType>
</Constraints>
</AvailablePerformers>
</SMLQuery>

Thanks for any advice anyone can give me. I really want to learn how to do this.

I am aware that an RSS feed xml file looks like this:

<?xml version="1.0" encoding="utf-8"?> <rss version="2.0"> <channel> <title>Website Feed</title> <description>Website Feed coded manually</description> <link>yourdomain.com</link>; <item> <title>A Special Event</title> <description>A Special Teleconference for our customers about our products</description> <link>yourdomain.com/events.htm</link>; </item> </channel> </rss>

But I am wanting to combine the data from the external xml file (from my first code snippet at the begining of this post) into an rss feed xml file, but retaining the use of my whitelabel url in the links.

UPDATE

Ok, I have tried merging some of the php code into an xml doc using an rss feed code structure, but obviously I am failing as I do not quite understand what I am doing here. I have searched google endlessly on this. Here is my attempt at merging the codes:

<?php
$curlData = '<?xml version="1.0" encoding="UTF-8"?>
<SMLQuery>
<Options MaxResults="20"/>
<AvailablePerformers Exact="false" PageNum="1" CountTotalResults="true">
<Include>
<Country/>
<Headline/>
<Descriptions></Descriptions>
<Rating/>
<Age/>
<Gender/>
<Media>biopic</Media>
<FreeChatSort/>
<PerformanceSort/>
</Include>
<Constraints> <StreamType>live,recorded,offline</StreamType>
<PublicProfile/>
<Name></Name><NoKeywords/>
<RelativeURLs/>
<NoKeywords/>
</Constraints>
</AvailablePerformers>
</SMLQuery>';
$url='http://affiliate.streamate.com/?????/SMLResult.xml';
$curl = curl_init();

curl_setopt ($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl,CURLOPT_TIMEOUT,120);
curl_setopt($curl,CURLOPT_HTTPHEADER,array (
'Content-Type: application/xml; charset=utf-8',
));
curl_setopt ($curl, CURLOPT_POST, 1);
curl_setopt ($curl, CURLOPT_POSTFIELDS, $curlData);

$result = curl_exec($curl);
curl_close ($curl);

$xml = simplexml_load_string ($result);
// $json = json_encode($xml);
// $array = json_decode($json,TRUE);

print_r ($result);
?>


<?xml version="1.0" encoding="utf-8"?> 
<rss version="2.0"> 
<channel> 
<title>Website Feed</title> 
<description>Website Feed coded manually</description>
<link>yourdomain.com</link>; 

<?php
foreach ($xml->AvailablePerformers->Performer as $perf) {

<item> 
<title><php? echo ".$perf->attributes()->Name ."?></title> 
<description><php? echo " .$perf->Descriptions->About ."?></description> 
<link><php? echo "<a href='http://www.mydomain.com/cam/".$perf->attributes()->Name."    /?AFNO=X-0-XXXXXX-XXXXXX&UHNSMTY=XXX?></link>; 
</item> 
</channel>
</rss>
?>

UPDATE 2

I have removed the print_r() as instructed and saved the following code as a php file, uploaded it, but all I am seeing is a blank white page. I dont know what to change re the header tag so can you explain where the header code should be and what I need to add/change please?

This is the code I now have, saved as a php file (or should it be an xml file? as I want it as an RSS feed, not a php webpage).

<?php
$curlData = '<?xml version="1.0" encoding="UTF-8"?>
            <SMLQuery>
<Options MaxResults="20"/>
<AvailablePerformers Exact="false" PageNum="1" CountTotalResults="true">

        </AvailablePerformers>
</SMLQuery>';
$url='http://affiliate.streamate.com/?????/SMLResult.xml';
$curl = curl_init();

curl_setopt ($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl,CURLOPT_TIMEOUT,120);
curl_setopt($curl,CURLOPT_HTTPHEADER,array (
'Content-Type: application/xml; charset=utf-8',
));
curl_setopt ($curl, CURLOPT_POST, 1);
curl_setopt ($curl, CURLOPT_POSTFIELDS, $curlData);

$result = curl_exec($curl);
curl_close ($curl);

$xml = simplexml_load_string ($result);
// $json = json_encode($xml);
// $array = json_decode($json,TRUE);


?>


<?xml version="1.0" encoding="utf-8"?> 
<rss version="2.0"> 
<channel> 
<title>Website Feed</title> 
<description>Website Feed coded manually</description>
<link>yourdomain.com</link>; 

<?php
foreach ($xml->AvailablePerformers->Performer as $perf) {

</rss>
?>

Just bumping this thread in hope someone can assist? Thanks.

UPDATE

ok I understand that I need to set the header content type. I have searched the web and found this:

<?php
header("Content-type:rss/xml");
?>

Is this correct for an rss feed? Where exactly in the page do I put this?

Also yet in my original code pasted above there is already a bit of code relating to content type stating:

'Content-Type: application/xml; charset=utf-8',
));

All I want is my original code to be an RSS Feed. I can't believe how difficult this is proving to find information on.

You want to turn your example into a usable RSS feed you can plug into your WL and other types of sites. This is very easy with what you had previously. As an example lets pretend you create a PHP page on the example domain below:

hxxp://www.example.com/pull_xml.php

Put inside it this content:

<?php
$curlData = '<?xml version="1.0" encoding="UTF-8"?>
<SMLQuery>
<Options MaxResults="20"/>
<AvailablePerformers Exact="false" PageNum="1" CountTotalResults="true">
<Include>
<Country/>
<Headline/>
<Descriptions></Descriptions>
<Rating/>
<Age/>
<Gender/>
<Media>biopic</Media>
<FreeChatSort/>
<PerformanceSort/>
</Include>
<Constraints> <StreamType>live,recorded,offline</StreamType>
<PublicProfile/>
<Name></Name><NoKeywords/>
<RelativeURLs/>
<NoKeywords/>
</Constraints>
</AvailablePerformers>
</SMLQuery>';

$url='http://affiliate.streamate.com/????/SMLResult.xml';
$curl = curl_init();

curl_setopt ($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl,CURLOPT_TIMEOUT,120);
curl_setopt($curl,CURLOPT_HTTPHEADER,array ('Content-Type: application/xml;       charset=utf-8',));
curl_setopt ($curl, CURLOPT_POST, 1);
curl_setopt ($curl, CURLOPT_POSTFIELDS, $curlData);

$result = curl_exec($curl);
curl_close ($curl);

echo $result;

?>

When you load that page into your browser you will see that it is an XML feed suitable for filling up your WL. To create a specific RSS feed from the data to work with a proprietary format expected by a certain service you will have to update your question with what format the feed should take. You can give an example of a feed you wish to emulate.

Also, you can change all URL's to your WL's URL structure by asking for the stream and substituting streamate.com with your whitelabel's domain.
