Php traversal to parse xml strings

This article mainly introduces php's method of traversing and parsing xml strings. it involves php's skills for reading, traversing, and parsing xml files based on SimpleXMLElement. it is very simple and practical, for more information about how to parse xml strings, see the example in this article. We will share this with you for your reference. The details are as follows:

 XML; $ test = new SimpleXMLElement ($ content); // Obtain the ping_protocol value $ ping_protocol = $ test-> global_setting-> ping_protocol; echo "ping_protocol: $ ping_protocol \ n "; // Print the IPforeach ($ test-> instances-> instance as $ instance) {echo "IP: {$ instance ['IP']} \ n";} of all instances ";} // after tests, it is found that the var_dump and the like cannot be effectively output, and echo is relatively smooth. // The above xml example can be removed.
 // You can also remove the header and tail. // <
