Question:
I have an html page that I want to edit. I want to remove a certain section like the following:
<ul class="agentDetail"> ........ ....... ........ </ul> I want to be able to remove the tags and all the content between them. The idea is to edit a page and redisplay it minus some data that I don't want to be seen (hence the removal of some sections).
How can I do this in php?
Solution:1
I would recommend parsing the code as XML, then using XPath to de/select the nodes you require. Here's a starting point:
$dom = getDom("http://www.stackoverflow.com"); parseDom($dom); function getDom($url) { $contentUtf8 = $this->fetchDataFromUrl($url); $htmlData = mb_convert_encoding($contentUtf8, 'HTML-ENTITIES', "UTF-8"); $dom = new DomDocument('1.0', 'utf-8'); $dom->substituteEntities = false; $dom->preserveWhitespace = false; @$dom->loadHTML($htmlData); return $dom; } function parseDom($dom) { $xpath = new DOMXPath($dom); $nodes = $xpath->query("//ul[@class='agentDetail']"); // manipulate nodes here... }
Solution:2
Are you hosting this page directly or are you reading it into php, and echoing it after parsing? In the former case, you can give it a .php extension and enclose those lines within <? if(0): ?> <? endif; ?> blocks
<?php if(0): ?> <ul class="agentDetail"> ........ ....... ........ </ul> <?php endif; ?> Note:If u also have question or solution just comment us below or mail us on toontricks1994@gmail.com
