How to correctly use PHP XmlReader parsing XML document _php Tutorial

We are using

The code examples for PHP XmlReader are as follows:

2. < ? PHP
4. Header ("content-type:text/html;
   Charset=utf-8 ");
6. $ URL = "http://www.google.com/
   Ig/api?weather=shenzhen ";
8. Loading XML content
10. $ XML = New XMLReader ();
12. $xml- > open ($url);
14. $ condition = '' ;
16. $ Temp_c = '' ;
18. While ($xml->Read ()) {
20. //Echo $xml- > name, "= = > ",
    $xml->depth, "<br>";
22. if (!empty ($condition)
    &&!empty ($temp _c)) {
24. Break
26. }
28. if ($xml->name = = ' condition '
    && empty ($condition)) {
30. Take the first one condition
32. $ condition = $xml- > getattribute (' data ');
34. }
36. if ($xml->name = = ' Temp_c ' &&
    Empty ($temp _c)) {
38. Take the first one Temp_c
40. $ Temp_c = $xml- > getattribute (' data ');
42. }
44. $xml- > read ();
46. }
48. $xml- > close ();
50. echo ' weather: ', $condition, ' < br />';
52. Echo ' temp: ', $temp _c, ' < br />';

We just need to use PHP XmlReader to take the first condition and the first temp_c, so traverse all the nodes, will encounter the first condition and the first Temp_c write variable, the last output.
