多个成员之间重复做相同的工作，很容易因为交流沟通的时候没有进行一致性的文档要求而出现不明错误，严重影响开发进度，导致在预定时间内无法完成该项目或者完成的项目跟原先计划所要实现的项目功能不符合。php5|xml 用 sax 体例的时分，要本人构建3个函数，并且要直接用这三的函数来前往数据，请求较强的逻辑。在处置分歧布局的 xml 的时分，还要从头停止机关这三个函数，费事！
用 dom 体例，却是好些，然而他把每一个节点都看做是一个 node,，操作起来要写很多多少的代码，费事！
网上有很多多少的开源的 xml 解析的类库，之前看过几个，然而心里老是感觉不扎实，感到老是跟在他人的屁股前面。
这几天在弄 Java，挺累的，所以决意换换脑壳，写点 PHP 代码，为了避免今后 XML 解析进程再令我犯难，就花了一天的工夫写了上面一个 XML 解析的类，因而就有了上面的器材。
完成体例是经由过程包装“sax体例的解析了局”来完成的。总的来讲，关于我团体来讲挺适用的，功能也还可以，根基上可以完成大多半的处置请求。
功效:
1\ 对根基的 XML 文件的节点停止 查询 / 添加 / 修正 / 删除 任务。
2\ 导出 XML 文件的一切数据到一个数组外面。
3\ 全部设计采取了 OO 体例,在操作了局集的时分，利用办法相似于 dom
弱点:
1\ 每一个节点最好都带有一个id(看前面的例子)，每一个“节点名字”=“节点的标签_节点的id”，假如这个 id 值没有设置，法式将主动给他发生一个 id，这个 id 就是这个节点在他的下级节点中的地位编号，从 0 入手下手。
2\ 查询某个节点的时分可以经由过程用“|”符号毗连“节点名字”来停止。这些“节点名字”都是按按次写好的下级节点的名字。
利用申明：
运转上面的例子，在履行了局页面上可以看到函数的利用申明
代码是经由过程 PHP5 来完成的，在 PHP4 中没法正常运转。
因为方才写完，所以没有收拾整顿文档，上面的例子演示的只是一局部的功效，代码不是很难，如果想晓得更多的功效，可以研讨研讨源代码。
