[RESOLVED] Extracting image from RSS feed

[Zpixel]

in the description tag of a feed, there are some images. i want to get their sources and save in a database.

suppose this is the description tag:

-<description> some text ... <img src="http://www.sth.com/image1.jpg"> .. some text ... <img src="http://www.sth.com/image2.jpg">
</description>

the description tag has been achived by this piece of code which i have no problem about it.

	$tnl = $item->getElementsByTagName("description");
	$tnl = $tnl->item(0);
	if(isset($tnl->firstChild->data))
	$description = $tnl->firstChild->data;

I wrote the code below to get the IMG tag:

	$tnl = $description ->getElementsByTagName("img");
	$tnl = $tnl->item(0);
	echo $image = $tnl->attributes->getNamedItem('src')->value;

but in the first line of the code above, an error is announced:

Fatal error: Call to a member function getElementsByTagName() on a non-object in /home/rsslibtest.php on line 63

how can i get images?
thanks.

IMG or img, no matter. just getting images.

I gave up DOOM. using string manipulation:

	$im_array=array();
    $desc=$description;
	while(1){
	$desc.=' ';
	$pos1=stripos($desc,"<img"); //">
	if($pos1){
	$pos2=strpos($desc,">",$pos1);
	$tag=substr($desc,$pos1,$pos2-$pos1);
	$pos3=strpos($tag,"http");
	$pos4=strrpos($tag,".");
    if(stripos($tag,"jpeg"))
	$image=substr($tag,$pos3,$pos4-$pos3+5);
    else
    $image=substr($tag,$pos3,$pos4-$pos3+4);
	$desc=substr($desc,$pos2+1,5000);

    if(stripos($image,"jpg") || stripos($image,"jpeg") ||
    stripos($image,"gif") || stripos($image,"bmp")){
    array_push($im_array,$image);
    }
	}
	else
	break;
	} //while

Well, you'd have to. <img> tags aren't part of RSS. They're just text; probably the whole description is a CDATA section so that the RSS parser doesn't choke on the ill-formed XML that would result in parsing <img> as (the start of) an XML element.

thank you.
