Scraping data using PHP Simple HTML DOM

Question

I structure like this:

<tr>
    <td>
        <strong>Tel. nr.:</strong>
        +370 000 000
        <strong>Faksas:</strong>
        +370 5 0000
    </td>
</tr>

I new in using Simple HTML DOM. What I need, I need content +370 000 000 and +370 5 0000 . I see that this library does not support Xpath, how can I write a query where I can extract the contents after the HTML link <strong>Tel. nr.:</strong> <strong>Tel. nr.:</strong> ?

I found only one way, get HTML and with regex get text from </strong> till <strong> , but maybe Simple HTML DOM have own method for this?

Answer 1

Try like this...

   <?php
    require('simple_parser.php');
    $html = str_get_html('
    <tr>
        <td>
            <strong>Tel. nr.:</strong>
            +370 000 000
            <strong>Faksas:</strong>
            +370 5 0000
        </td>
    </tr>');
    $td =$html->find('td',0) ; 
    echo $td->plaintext;

    ?>

You could use ->find('text') in order to get the text nodes:

$sample_html = '
<table>
<tr>
    <td>
        <strong>Tel. nr.:</strong>
        +370 000 000
        <strong>Faksas:</strong>
        +370 5 0000
    </td>
</tr>
</table>
';

$html = str_get_html($sample_html);
foreach($html->find('tr') as $row) {
    $first_td = $row->find('td', 0);
    echo $first_td->find('text', 2);
    echo $first_td->find('text', 4);
}

But this solution is rather clunky. One removal of those newlines on the elements would yield another result.

I suggest use DOMDocument with xpath instead:

$dom = new DOMDocument;
$dom->loadHTML($sample_html);
$xpath = new DOMXpath($dom);
$elements = $xpath->query('//tr[1]/td[1]/text()');
foreach($elements as $e) {
    echo trim($e->textContent) . '<br/>';
}
