Using DomDocument to involve a element with another element? - php

Question

I have tree divs inside a father div called results_all as you can see below:
<div id="results_all">
<div class="result_information">
</div>
<div class="result_information">
</div>
<div class="result_information">
</div>
</div>
all I want to do is involve all divs whose class is called result_information, with the following code <tr><th>.
so that the final results to be:
<tr><th>
<div class="result_information">
</div>
</th></tr>
<tr><th>
<div class="result_information">
</div>
</th></tr>
<tr><th>
<div class="result_information">
</div>
</th></tr>
How I can do this kind of thing using DomDocument with PHP?

Answer 1

This will match the class using DOMXPath, it's then just a case of outputting the matched content with the appropriate tags when you loop over the results.
$html = '<div id="results_all">
<div class="result_information">
test3
</div>
<div class="result_information">
test2
</div>
<div class="result_information">
test
</div>
</div>
';
$classname = 'result_information';
$dom = new DOMDocument;
$dom->loadHTML($html);
$xpath = new DOMXPath($dom);
$results = $xpath->query("//*[contains(#class, '$classname')]");
for($i = 0; $i < $results->length; $i++ ){
print '<tr><th><div class="result_information">' . $results->item($i)->nodeValue . '</div></tr></th>';
}
