Having trouble with preg_match !! Please Help

[guvnoruk]

I am a complete newbie with PHP. but i am making progress.

 

So this is how far i got. I am trying to reformat an xml feed to get it working with my flash widget.

 

So i am using the orginal feed using PHP to format it and then use it. I used "getElementsByTagName" and formatted all what i wanted but now i just stuck with one thing. How to code so that i can get the image url from the xml feed.

 

The problem is the img url is not something i can get by "getElementsByTagName" because its inside a TAG: i dunno if i make sense but here is the xml feed:

 

<item>
<title><![CDATA[sEXY UNIQUE PINK GOGO TOP SHORT WRAP AROUND 6  8 10 12]]></title>
<link><![CDATA[http://cgi.ebay.co.uk/SEXY-UNIQUE-PINK-GOGO-TOP-SHORT-WRAP-AROUND-6-8-10-12_W0QQitemZ380126183045QQcmdZViewItemQQssPageNameZRSS:B:SILF:GB:101]]></link>
<description><![CDATA[<table border="0" cellpadding="8"><tr><td><a href="http://cgi.ebay.co.uk/SEXY-UNIQUE-PINK-GOGO-TOP-SHORT-WRAP-AROUND-6-8-10-12_W0QQitemZ380126183045QQcmdZViewItemQQssPageNameZRSS:B:SILF:GB:102"><img border="0" src="http://thumbs.ebaystatic.com/pict/380126183045_0.jpg"></a></td><td><strong>&#163;7.99</strong><br /> End Date: Sunday Jun-21-2009 18:07:40 BST<br />Buy It Now for only: &#163;7.99<br /><a href="http://cgi.ebay.co.uk/SEXY-UNIQUE-PINK-GOGO-TOP-SHORT-WRAP-AROUND-6-8-10-12_W0QQitemZ380126183045QQcmdZViewItemQQssPageNameZRSS:B:SILF:GB:105">Buy it now</a> | <a href="http://cgi1.ebay.co.uk/ws/eBayISAPI.dll?MfcISAPICommand=MakeTrack&item=380126183045&ssPageName=RSS:B:SILF:GB:104">Add to watch list</a></td></tr></table>]]></description>

<rx:ItemCharacteristic xmlns:rx="urn:ebay:apis:eBLBaseComponents">Listed with PayPal</rx:ItemCharacteristic>
</item>

 

 

Now This is the url i need to specify src="http://thumbs.ebaystatic.com/pict/380126183045_0.jpg, which is under the description tag. I need the value of this URL as a seprate TAG

 

so that i can create my feed for the flash widget.

 

The PHP Is as follows:

 

<?php
$xml = new DomDocument;
$xml -> load("http://rss.api.ebay.com/ws/rssapi?FeedName=StoreItems&siteId=3&language=en-GB&output=RSS20&storeId=116907097");
$str = "";
//get elements from "<channel>"
$channel=$xml->getElementsByTagName('channel')->item(0);
$channel_title = $channel->getElementsByTagName('title')->item(0)->childNodes->item(0)->nodeValue;
$channel_link = $channel->getElementsByTagName('link')->item(0)->childNodes->item(0)->nodeValue;
$channel_desc = $channel->getElementsByTagName('description')->item(0)->childNodes->item(0)->nodeValue;

//output elements from "<channel>"
$str .= "<p><strong><a href='". $channel_link."'>".$channel_title."</a></strong>";
$str .= "<br />";
$str .= $channel_desc . "</p>" ;

$node=$xml->getElementsByTagName('item');
$i=0;
$str .= "<ul>";
$str .= "<list>"."\n";

foreach($node as $x){
$item_title=$x->getElementsByTagName('title')->item(0)->childNodes->item(0)->nodeValue;
$item_link=$x->getElementsByTagName('link')->item(0)->childNodes->item(0)->nodeValue;
$item_desc=$x->getElementsByTagName('description')->item(0)->childNodes->item(0)->nodeValue;
$item_date=$x->getElementsByTagName('pubDate')->item(0)->childNodes->item(0)->nodeValue;
$item_image=$x->preg_match('/src=['"]?([^'" >]+)['" >]/',$item_desc,$result);

//$str .= "<li><a href='".$item_link."'>".$item_title ."</a></li><ul><li>";
//$str .= $item_desc . "</li></ul>";
//$str .="<list>"."\n";
$str .="<item>"."\n";
$str .="<date>".$item_date."</date>"."\n";
$str .="<headline>".$item_title."</headline>"."\n";
$str .="<image>".$item_image."</image>"."\n";
  $str .="<news_text><![CDATA[".$item_desc."]]></news_text></item>"."\n";
$i++;
}
//$str .= "</ul>";
$str .= "</list>";
echo $str;
?>

 

Please guys dont laugh :-) but i thought if i use $item_image=$x->preg_match('/src=[\'"]?([^\'" >]+)[\'" >]/',$item_desc,$result);, it might just work but hey it doesnt dunno what to use to get this working .

 

I would be really greateful if someone can point me to the right direction.

 

So in short i want to extract a URL which is under the description TAG for everything in the array. I dunno if i make sense but i think i tried my best.

 

Regards
