feed import

[ravi181229]

Hi,

 

I am trying to import a feed and read it using SimpleXMLElement.

first I found that it has extra characters at the beginning and at the end, so I wrote code which removes extra characters  :

$link = 'http://ustream.tv/live.rss';

$rss_feed = file_get_contents($link);

//$rss_feed = str_replace("utf-8", "iso-8859-1", $rss_feed);

$rss_feed = substr($rss_feed, 5);

$rss_feed = ltrim($rss_feed);

$rss_feed = substr($rss_feed, 0, -5);

$rss_feed = rtrim($rss_feed);

$ustream = new SimpleXMLElement($rss_feed);

$casts = $ustream->channel->item;

foreach ($casts as $cast) {

    echo "<br>Title:".$cast->title;

}

 

but still it displays error.

 

I need your help.

 

Thanks,

Ravi

What do the errors say...?

Error type: Php Warning

Message: SimpleXMLElement::__construct() [function.SimpleXMLElement---construct]: Entity: line 276: parser error : Opening and ending tag mismatch: description line 268 and style

And what are these characters that you're stripping out of $rss_feed before passing it to SimpleXMLElement?

[ravi181229]

these are extra characters, like :

32a45

<?xm..........?>

</rss>

0

I don't know about the 32a45 and 0

But I suspect that the <?xm..........?> and </rss> are probably pretty critical for SimpleXMLElement to work. It looks as though you're rendering the XML invalid by removing these.
