How can I get an element's serialised HTML with PHP's DOMDocument?
This is my example script:
$html = <<<HTML
<div class="main">
<div class="text">
Capture this text 1
</div>
<div class="date">
May 2010
</div>
</div>
<div class="main">
<div class="text">
Capture this text 2
</div>
<div class="date">
June 2010
</div>
</div>
HTML;
$dom = new DOMDocument();
$dom->loadHTML($html);
$xpath = new DOMXPath($dom);
$tags = $xpath->query('//div[@class="main"]');
foreach ($tags as $tag) {
print_r($tag->nodeValue."\n");
}
This will out put:开发者_Python百科
Capture this text 1 May 2010
Capture this text 2 June 2010
But I need it output:
<div class="text">
Capture this text 2
</div>
<div class="date">
June 2010
</div>
Or atleast be able to do something like this in my foreach loop:
$text = $tag->query('//div[@class="text"]')->nodeValue;
$date = $tag->query('//div[@class="date"]')->nodeValue;
Well, nodeValue will give you the node's value. You want what's commonly called outerHTML
echo $dom->saveXml($tag);
will output what you are looking for in an X(HT)ML compliant way.
As of PHP 5.3.6 you can also pass a node to saveHtml, which wasnt possible previously:
echo $dom->saveHtml($tag);
The latter will obey HTML4 syntax. Thanks to Artefacto for that.
try this
$dom = new DOMDocument();
$dom->loadHTML($html);
$xpath = new DOMXPath($dom);
$tags = $xpath->query('//div[@class="main"]');
foreach ($tags as $tag) {
$innerHTML = '';
$children = $tag->childNodes;
foreach ($children as $child) {
$tmp_doc = new DOMDocument();
$tmp_doc->appendChild($tmp_doc->importNode($child,true));
$innerHTML .= $tmp_doc->saveHTML();
}
var_dump(trim($innerHTML));
}
