Скрининг экрана с использованием SimpleHTMLDom

Question

Пытается отобразить содержимое лома в php и назначить массив. Мне нужны следующие данные, используя библиотеку 'SimpltHTMLDom' референс: Parse html table using file_get_contents to php array

Желаемые результаты:

• больницы Имя цвет фона в <text> (CSS) (если он существует !!!)
  • необходимость все пяти <text> (как ноль, если нет цвета фона)

Массив:

Hospital 1  
--> NULL  
--> #ff0000  
--> 08:50  
--> NULL  
--> NULL 

Hospital 2  
--> #ffff00  
--> 08:50  
--> NULL  
--> NULL  
--> NULL 

PHP:

<?php 
require('simple_html_dom.php'); 
$table = array(); 


$html = file_get_html('https://www.miemssalert.com/chats/Default.aspx?hdRegion=3'); 
foreach($html->find('table#tblHospitals tr') as $row) { 
    $hospital = $row->find('td.Chats',0)->plaintext; 
    $color = $row->getAttribute('td.Chats style',2); 
    $time = $row->find('td.Chats',2)->plaintext; 
    //$text = $row->getAttribute('alt'); 

$table[$hospital][$color][$time][$text] = true; 

} 

echo '<pre>'; 
print_r($table); 
echo '</pre>'; 
?> 

HTML, в DOM (это небольшой пример страницы):

<div id="Page1" style="display: none; width: 100%;"> 
           <div id="HospitalUpdatePanel"> 

             <table id="tblHospitals" cellspacing="0" cellpadding="1" align="Left" rules="all" border="1" style="border-color:Black;border-width:1px;border-style:Solid;width:100%;border-collapse:collapse;table-layout: fixed;">

Answer 1

Есть несколько проблем, с посланным кодом:

1. Метод find() принимает селектор CSS, а не HTML разметки. Если вы хотите найти <table id="tblHospitals">, используйте table#tblHospitals и так далее.
2. foreach($html->find(table#tblHospitals') as $row) будет перебирать один элемент таблицы, а не строки. Вы можете использовать селектор, который выбирает фактические элементы строки, например: table#tblHospitals tr

Answer 2

оказалось только две строки кода:

<?php 
require('simple_html_dom.php'); 

$html = file_get_html('https://www.miemssalert.com/chats/Default.aspx?hdRegion=3'); 
foreach($html->find('table#tblHospitals tr td.Chats') as $e) 
    echo $e->plaintext . $e->getAttribute('style') . '<hr>'; 
?> 

результаты массив выглядит следующим образом:

array(37) { 
    ["Anne Arundel Medical Center"]=> 
    array(1) { 
    [0]=> 
    bool(true) 
    } 
    [""]=> 
    array(1) { 
    [0]=> 
    bool(true) 
    } 
    ["Baltimore Washington Medical Center"]=> 
    array(1) { 
    [0]=> 
    bool(true) 
    } 
    ["04:31"]=> 
    array(1) { 
    ["background-color:#ffff00;color:#000000;"]=> 
    bool(true) 
    } 
    ["Bon Secours Hospital"]=> 
    array(1) { 
    [0]=> 
    bool(true) 
    }
