PHP uses simplexml to parse xml
code show as below:
$xml = <<<XML <?xml version="1.0" encoding="UTF-8"?> <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"> <url> <loc>http://www.php.cn/;/loc> <lastmod>2013-06-13 01:20:01</lastmod> <changefreq>always</changefreq> <priority>1.0</priority> </url> <url> <loc>http://www.php.cn/;/loc> <lastmod>2013-06-13 01:20:01</lastmod> <changefreq>always</changefreq> <priority>0.8</priority> </url> </urlset> 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] => http://www.php.cn/ [lastmod] => 2013-06-13 01:20:01 [changefreq] => always [priority] => 1.0 ) [1] => SimpleXMLElement Object ( [loc] => http://www.php.cn/ [lastmod] => 2013-06-13 01:20:01 [changefreq] => always [priority] => 0.8 ) ) )
We can see that the result is in the format of an object or array, so that we can easily obtain the value of each element in XML
foreach ($simple->url as $val){ print $val->loc; }
The loc value of each item will be output here.

The implementation of RSS in XML is to organize content through a structured XML format. 1) RSS uses XML as the data exchange format, including elements such as channel information and project list. 2) When generating RSS files, content must be organized according to specifications and published to the server for subscription. 3) RSS files can be subscribed through a reader or plug-in to automatically update the content.

Advanced features of RSS include content namespaces, extension modules, and conditional subscriptions. 1) Content namespace extends RSS functionality, 2) Extended modules such as DublinCore or iTunes to add metadata, 3) Conditional subscription filters entries based on specific conditions. These functions are implemented by adding XML elements and attributes to improve information acquisition efficiency.

RSS documents are XML-based structured files used to publish and subscribe to frequently updated content.

RSS documents work by publishing content updates through XML files, and users subscribe and receive notifications through RSS readers. 1. Content publisher creates and updates RSS documents. 2. The RSS reader regularly accesses and parses XML files. 3. Users browse and read updated content. Example of usage: Subscribe to TechCrunch's RSS feed, just copy the link to the RSS reader.
