解析 HTML 表格如何使用 PHP 解析单元格和行

Question

<?php

    include ("simpel_html_dom.php");
    $dom = new \DOMDocument();
    $dom->loadHTML('http://www.arbworld.net/en/moneyway');

    $xpath = new \DomXPath($dom);

    // query the first column with class "value" of the table with class "attributes"
    $elements = $xpath->query('(/table[@class="grid"]//tr[@class="belowHeader"])');

    // iterate through all found td elements
    foreach ($elements as $element) {
        echo $element->nodeValue;
    }
?>

I would to scrape the HTML table but when I run the code the result will be an empty page. How can I resolve it?

Answer 1

That HTML is badly formed ( according to libxml ) so you need to account for that when loading the source data which, incidentally, you do either with loadHTMLFile to load a url or loadHTML to load a string of HTML.

$url='http://www.arbworld.net/en/moneyway';
libxml_use_internal_errors( true );
$dom=new DOMDocument;
$dom->validateOnParse=false;
$dom->recover=true;
$dom->strictErrorChecking=false;
$dom->loadHTMLFile( $url );
libxml_clear_errors();


$xp=new DOMXPath( $dom );
$col=$xp->query('//table[@class="grid"]/tr[@class="belowHeader"]/td');

if( $col->length > 0 ){
    foreach( $col as $node )echo $node->textContent;
}

I would like to see it like in IMG and not in this way :

I would see it in columns and rows

Understand?
