在PHP中使用XML
PHP包含支持Expat 解析器的可选XML扩展。PHP中的XML相关函数可以让你创建一个解析器来处理有效的XML文档。如果你所使用的Apache版本为1.3.7后的版本，则不用添加任何函数库。所需要做的只是使用--with-xml配置PHP。
在PHP手册中有好几个创建基于PHP的XML解析器很好的例子。此外，New Riders的Web Application Development with PHP 4.0对在PHP中使用XML有很好的概括，该书作者之一已在Zend.com 上撰写了大量指南。
如同对Java和COM支持一样,PHP对XML的支持还处于发展迅速的幼儿期。如果你已经具备Expat或LibXML相关经验，可以利用你的专门知识略过一些内容。
