simpleXML get value from CDATA

I'm trying to get values from CDATA which are inside <b></b>. with simpleXML, but so far without any good results. Here is some part of my xml file -

<item>
<title>

I know how to get values from this xml file like title, pudDate, link, but I don't know how can I get values from description tag so I can add them into database sorted by Price, District, Type, Image.

So far I tryed to save description tag into string and after that using explode() cut out parts with info I need, I have the right values but they come with tags. Some with tags.

This is what I was trying -

$url = "http://ift.tt/1qEgoQd";

$result = simplexml_load_file($url);

foreach ($result->channel->item as $item) {
    $title =(string)$item->title;
    description = (string)$item->description;
    $link = $item->link;
    $pubDate = $item->pubDate;

// Cut out from description price
    $parts = explode("Price: ", $description);
    $pri= "";
    for ($i = 1; $i < 2; $i++) {
        $pri= $parts[$i];
    }
    $parts2 = explode("</b>", $pri);
    for ($i = 1; $i < 2; $i++) {
        $price= $parts2[0];
    }

but I think my solution is absoloutly wrong and the result of cutting is - <b><b>300 or <b>650

so my question is: how can I get clean values out of my CDATA using something similar to

$pubDate = $item->pubDate

using something like that?

$description = (string)$item->description->b[0] - to get right values from CDATA.
