在PHP简单HTML DOM解析器中查找元素的正则表达式 [英] regexp on finding elements in PHP Simple HTML DOM Parser

问题描述

我该如何找到"相关信息?所有具有这些ID的元素:

How can i "find" all elements with those id:

ctl00_cphContent_ctl05_Panel01，

ctl00_cphContent_ctl05_Panel01,

ctl00_cphContent_ctl06_Panel01，

ctl00_cphContent_ctl06_Panel01,

ctl00_cphContent_ctl07_Panel01，

ctl00_cphContent_ctl07_Panel01,

ctl00_cphContent_ctl08_Panel01， 等等...

ctl00_cphContent_ctl08_Panel01, etc...

我尝试过

foreach($html->find('a#ctl00_cphContent_ctl'.*.'_Panel01') as $positions) { echo "Test!";}

但是它不起作用！有谁可以帮助我吗?我搜索了但没有找到类似的东西...

But it doesn't work! Can someone help me please? I search but didn't find something similar...

推荐答案

从阅读简单的HTML DOM解析文档开始

From reading the simple HTML DOM parses documentation http://simplehtmldom.sourceforge.net/manual.htm#section_find, I don't think that it includes full regex functionality. However it does seem to have basic matching. Try this:

$html->find( '[id^=ctl00_cphContent_ctl]' )

很显然，这将不匹配ID标记(例如ctl00_cphContent_ctl05_Panel01)，但也将匹配ctl00_cphContent_ctrandomstuffhere之类的东西.但是似乎无法按照您想要的方式进行完整的正则表达式匹配.

Obviously this wont just match id tags like ctl00_cphContent_ctl05_Panel01, but will also match things like ctl00_cphContent_ctrandomstuffhere. But it doesn't appear to be possible to do a full regexp match in the way you want.
