从PHP简单HTML DOM解析器中删除html标签

Question

I wanna delete some words from simple_html_dom when get external data (eg name of Author or name of website ) from this code: `

<?php
ini_set('display_errors',1);
ini_set('display_startup_errors',1);
error_reporting(-1);

include('simple_html_dom.php');  
$html = new simple_html_dom();

// Create DOM from URL or file


$html = file_get_html('http://www.example.com');       

$myContent = $html->find('table', 0)->plaintext;
echo $myContent;

I don't know how can do it (delete flowing code from a table from url)

  <tr style="background: #ffd700;color:black;">

    <td colspan="5">**delete this words from table..**   
    </td></tr>

Answer 1

you can also delete directly from the dom the innertext between your TD

$html->find('table tr')->children(NUMBER OF THE TD TO EMPTY)->innertext = '';

here is the doc for simpleHtmlDomParser

How to delete a td from a table in the simple_html_dom ?

Answer 3

In my case, I'm grabbing a table, and needed to remove the tfoot. Did so like:

include("simple_html_dom.php");
$html = str_get_html($curl_response_html); // load html from string
$wtable = $html->find('table[id=sometableid]',0); // get table by id
$wtable->find('tfoot',0)->outertext=''; // find the element in the table and remove it
echo $wtable;

In your case, if you want to remove the whole row and you know the table row number, you can do something like:

$wtable = $html->find('table[id=sometableid]',0); // get table by id
$wtable->find('tr',0)->outertext=''; // find the element in the table and remove it

Where 'tr', 0 that would remove the first row, and 'tr', 3 would remove the fourth row.

Or even:

$wtable = $html->find('table[id=sometableid]',0); // get table by id
$wtable->find('td[colspan=5]',0)->innertext=''; // find the element and remove its contents

That would get the first cell with colspan 5 and remove its contents.
