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 = &#39;http://www.php230.com/baidu_sitemap1.xml&#39;;
// $simple = simplexml_load_file($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.
