用 PHP5 輕松解析 XML
更新時(shí)間：2006年12月04日 00:00:00 作者：
用 sax 方式的時(shí)候，要自己構(gòu)建3個(gè)函數(shù)，而且要直接用這三的函數(shù)來(lái)返回?cái)?shù)據(jù)，要求較強(qiáng)的邏輯。在處理不同結(jié)構(gòu)的 xml 的時(shí)候，還要重新進(jìn)行構(gòu)造這三個(gè)函數(shù)，麻煩！
用 dom 方式，倒是好些，但是他把每個(gè)節(jié)點(diǎn)都看作是一個(gè) node,，操作起來(lái)要寫(xiě)好多的代碼，麻煩！
網(wǎng)上有好多的開(kāi)源的 xml 解析的類(lèi)庫(kù)，以前看過(guò)幾個(gè)，但是心里總是覺(jué)得不踏實(shí)，感覺(jué)總是跟在別人的屁股后面。
這幾天在搞 Java，挺累的，所以決定換換腦袋，寫(xiě)點(diǎn) PHP 代碼，為了防止以后 XML 解析過(guò)程再令我犯難，就花了一天的時(shí)間寫(xiě)了下面一個(gè) XML 解析的類(lèi)，于是就有了下面的東西。
實(shí)現(xiàn)方式是通過(guò)包裝“sax方式的解析結(jié)果”來(lái)實(shí)現(xiàn)的?？偟膩?lái)說(shuō)，對(duì)于我個(gè)人來(lái)說(shuō)挺實(shí)用的，性能也還可以，基本上可以完成大多數(shù)的處理要求。
功能:
1\ 對(duì)基本的 XML 文件的節(jié)點(diǎn)進(jìn)行 查詢 / 添加 / 修改 / 刪除 工作。
2\ 導(dǎo)出 XML 文件的所有數(shù)據(jù)到一個(gè)數(shù)組里面。
3\ 整個(gè)設(shè)計(jì)采用了 OO 方式,在操作結(jié)果集的時(shí)候，使用方法類(lèi)似于 dom
缺點(diǎn):
1\ 每個(gè)節(jié)點(diǎn)最好都帶有一個(gè)id(看后面的例子)，每個(gè)“節(jié)點(diǎn)名字”=“節(jié)點(diǎn)的標(biāo)簽_節(jié)點(diǎn)的id”，如果這個(gè) id 值沒(méi)有設(shè)置，程序?qū)⒆詣?dòng)給他產(chǎn)生一個(gè) id，這個(gè) id 就是這個(gè)節(jié)點(diǎn)在他的上級(jí)節(jié)點(diǎn)中的位置編號(hào)，從 0 開(kāi)始。
2\ 查詢某個(gè)節(jié)點(diǎn)的時(shí)候可以通過(guò)用“|”符號(hào)連接“節(jié)點(diǎn)名字”來(lái)進(jìn)行。這些“節(jié)點(diǎn)名字”都是按順序?qū)懞玫纳霞?jí)節(jié)點(diǎn)的名字。
使用說(shuō)明：
運(yùn)行下面的例子，在執(zhí)行結(jié)果頁(yè)面上可以看到函數(shù)的使用說(shuō)明
代碼是通過(guò) PHP5 來(lái)實(shí)現(xiàn)的，在 PHP4 中無(wú)法正常運(yùn)行。
由于剛剛寫(xiě)完，所以沒(méi)有整理文檔，下面的例子演示的只是一部分的功能，代碼不是很難，要是想知道更多的功能，可以研究研究源代碼。
