data inside XML string

Hello,
The following link will give you the number of the Inbound link to some url:
http://search.yahooapis.com/SiteExplore ... output=xml

In the top you can find "totalResultsAvailable=14370725"
how can I get the number into varibale?

I tried this:

<?PHP
$resp = file_get_contents("http://search.yahooapis.com/SiteExplorerService/V1/inlinkData?appid=YahooDemo&query=http://www.cnn.com&omit_inlinks=domain&output=xml");
$xml = simplexml_load_string($resp);
echo $xml->ResultSet['totalResultsAvailable'];
?>

PHP:

But its not working...:/

 

Its an attribute

<?PHP
$resp = file_get_contents("http://search.yahooapis.com/SiteExplorerService/V1/inlinkData?appid=YahooDemo&query=http://www.cnn.com&omit_inlinks=domain&output=xml");
$xml = simplexml_load_string($resp);

#echo $xml->ResultSet['totalResultsAvailable'];
print $xml['totalResultsAvailable'];
?>

PHP:

 

Thank you,
It's working.

What did you mean by attribute?
attribute is something that conect to XML?

 

An attribute is something associated with a node (in this case its the parent tree but as an example)

<xml>
<person type="man">
<heigh>tall</height>
<haircolor>brown</haircolor>
</person>
</xml?

in the above 'type="man"' is an attribute of person and these values and handled differently to the child nodes within person.

 

Thank you
