如何通过XML文件使用PHP进行搜索并显示结果？

问题描述：

You might want to check out http://php.net/manual/en/class.xmlreader.php

Using that it is pretty easy to navigate through an XML file and grab all the info you need.

EDIT: On second thought, http://php.net/manual/en/book.simplexml.php is a MUCH simpler way to achieve what you're trying to do. Hence the name, I guess ;)

You can use SimpleXML library to parse your xml file. In my opinion SimpleXML is easier to use than xmlreader. Though SimpleXML is introduced on php5.
