Code example for parsing XML Element structures in PHP

PHP code for parsing the XML element structure:

1. <? Php
2. $ File = "data. xml ";
3. $ Depth = array ();
4. Function startElement
   ($ Parser, $ name, $ attrs ){
5. Global $ depth;
6. For ($ I = 0; $ I <$ depth
   [$ Parser]; $ I ++ ){
7. Print "";
8. }
9. Print "$ namen ";
10. $ Depth [$ parser] ++;
11. }
12. Function endElement ($ parser, $ name ){
13. Global $ depth;
14. $ Depth [$ parser] --;
15. }
16. $ Xml_parser = xml_parser_create ();
17. Xml_set_element_handler ($ xml_parser,
    "StartElement", "endElement ");
18. If (! ($ Fp = fopen ($ file, "r "))){
19. Die ("cocould not open XML input ");
20. }
21. While ($ data = fread ($ fp, 4096 )){
22. If (! Xml_parse ($ xml_parser,
    $ Data, feof ($ fp ))){
23. Die (sprintf ("XML error: % s at line % d ",
24. Xml_error_string (xml_get _
    Error_code ($ xml_parser )),
25. Xml_get_current_line _
    Number ($ xml_parser )));
26. }
27. }
28. Xml_parser_free ($ xml_parser );
29. ?>

The above code example is a detailed analysis of PHP parsing XML element structure. I hope you can fully understand it.
