How to correctly use PHP XMLReader to parse XML documents_PHP Tutorial

The code example we are using

PHP XMLReader is as follows:

1. < ?PHP
2. header("Content-type:text/html;
   Charset=utf-8");
3. $url = "http: //www.google.com/
   ig/api?weather=shenzhen";
4. // Load XML content
5. $xml = new XMLReader();
6. $ xml->open($url);
7. $condition = ''; 🎜>;
8. while ($xml->read()) { >// echo $xml->
name, "==
9. >", $xml ->
10. depth, "<br>";
    if (!empty($condition) && !empty($temp_c)) { break; }
11. if ($xml-
    >
name
12. == 'condition ' && empty($condition)) {
13. // Take the first condition
14. $ condition = $xml-
    >
getAttribute('data');
}
16. if ($xml->name == 'temp_c' && empty($temp_c)) {
17. // Get the first temp_c
18. $temp_c = $xml-
    >
getAttribute('data');
}
20. $xml- >read();
}
$xml-
22. > ;close();
echo 'Weather:', $condition, '
23. <
24. br />
';
25. echo 'Temperature:', $temp_c, '< br />
';
26. We just need to use PHP XMLReader to get the first condition and the first temp_c, then traverse all the nodes and write the first condition and the first temp_c encountered into variables , and finally output. http://www.bkjia.com/PHPjc/446186.html
