Parsing OpenSearch XML data?

[cahamilton]

Can anyone tell me how it is possible to parse the "totalResults" item in and OpenSearch XML document such as this one:

http://ws.audioscrobbler.com/2.0/?api_key=c7d55f27a911c6a0f77040f18758fc5a&method=artist.search&artist=ehfdfjfgjvhfgndfobndfhnfdgnhdfh

 

I've been working on it for about 2 hours and I can't seem to figure it out ???

 

So far I have:

 

<?php
$lastFM_url = 'http://ws.audioscrobbler.com/2.0/?api_key=c7d55f27a911c6a0f77040f18758fc5a&method=artist.search&artist=';
$lastFM_search_results = $lastFM_url.$artist_query;

// read feed into SimpleXML object
      $lastFM_searchXML = simplexml_load_file($lastFM_search_results);
      
      // get summary counts from opensearch: namespace
      $counts = $lastFM_searchXML->results->children('http://a9.com/-/spec/opensearchrss/1.0/');
      $total = $counts->totalResults;  

?> 

 

Anyone have any ideas?

What exactly are you trying to do?  What do you want to extract?

 

You should probably read up on, "XPath".

Taking this feed for example:

http://ws.audioscrobbler.com/2.0/?api_key=c7d55f27a911c6a0f77040f18758fc5a&method=artist.search&artist=muse

 

I'm simply trying to extract the <opensearch:totalResults> of the feed. Because of the structure of this feed is different to all others I have worked with (this is an OpenSearch feed), its proving difficult to understand and get the correct syntax for extracting that element of the feed.
