Php uses simplexml to parse xml

The code is as follows:

$xml = <<
 
      
           
    
     #;/loc>        
     
      2013-06-13 01:20:01
             
     
      always
             
     
      1.0
         
    
       
           
    
     #;/loc>        
     
      2013-06-13 01:20:01
             
     
      always
             
     
      0.8
         
    
   
  XML;$simple =  simplexml_load_string($xml);// $url = 'http://www.php230.com/baidu_sitemap1.xml';// $simple = simplexml_load_file($url);
 

Here we can check the format of $ simple:

print_r($simple);

SimpleXMLElement Object(    [url] => Array        (            [0] => SimpleXMLElement Object                (                    [loc] => #                    [lastmod] => 2013-06-13 01:20:01                    [changefreq] => always                    [priority] => 1.0                )            [1] => SimpleXMLElement Object                (                    [loc] => #                    [lastmod] => 2013-06-13 01:20:01                    [changefreq] => always                    [priority] => 0.8                )        ))

We can see that the results are in the format of objects and arrays, so that we can easily obtain the values of each element in XML.

foreach ($simple->url as $val){    print $val->loc;}

Here, the loc value of each item is output.
