An in-depth explanation of PHP Domxpath's role in parsing XML files _php Tutorials

When using

Examples of how PHP Domxpath are used:

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. $ Dom = New DOMDocument ();
12. $dom- > load ($url);
14. $ XPath = New Domxpath ($dom);
16. $ element = $xpath- > Query ("/xml_api_reply
    /weather/current_conditions ")->item (0);
18. $ condition = Get_google_xml_data
    ($element, "condition");
20. $ Temp_c = Get_google_xml_data
    ($element, "Temp_c");
22. echo ' weather: ', $condition, ' < br />';
24. Echo ' temp: ', $temp _c, ' < br />';
26. function Get_google_xml_data
    ($element, $tagname) {
28. $ Tags = $element- >
    getElementsByTagName ($tagname);
30. Get all the $tagname
32. if ($items->length > 1) {
34. return $items;
36. }
38. $ Tag = $tags- > item (0);
40. Gets the first label named $tagname
42. if ($tag->hasattributes ()) {
44. Get the Data property
46. $ attribute = $tag- >
    getattribute ("data");
48. return $attribute;
50. }else {
52. return false;
54. }
56. }
58. ?>

I hope that through the above code example, we can fully grasp the specific use of PHP Domxpath method.
