I know it's not answer to this question, but don't use regular expressions for manipulating with DOM. There are specialized classes for that (DOMDocument), which are faster and will cause you less headache.

How access nested elements with repeated class xpath

I need access a nested element with repeated class, like that:
<div class="container">
<div class="first"></div>
<div class="first"></div>
<div class="first">
<div class="second"></div>
<div class="second">
<p>I need that text</p>
</div>
</div>
</div>
So i try something like that:
$localizacao_x = $xpath_det_page->query('//div[#class="container"]/div[#class="first"][3]/div[#class="second"][2]/p');
$localizacao = $localizacao_x->item(0)->nodeValue;
echo "[Localizacao] : [".$localizacao."]"."<br/>";
But result in non object, any tip?

Your XPath seems to be correct. I tested
//div[#class="container"]/div[#class="first"][3]/div[#class="second"][2]/p
which result is
I need that text

Couldnt grab div element with a specified class name using simple_html_dom?

<div class="-flair">
';
echo $html->find('div[class=user-details]',0);
?>
What am i doing wrong here i am getting error Call to a member function find() on string in
Thanks!

You are tying to use Simple Html Dom to parse an html string.
Do not assign your html string to $html variable.
Assign it to an other, like $html_string.
Then use $html = str_get_html($html_string)
and
echo $html->find('div[class=user-details]',0);

You trying to call object method on a string variable. It should works:
$html = str_get_html('<div class="user-info ">
<div class="user-action-time">
answered <span title="2016-06-27 20:01:45Z" class="relativetime">Jun 27 at 20:01</span>

Xpath Exclude p.class of a div

This is my HTML example:
<div id="Texte">
<div class="pagination">
...
</div>
<p>...</p>
<p>....</p>
<p class="Foot">...</p>
</div>
I want to use Xpath to get all content of my <div id="Texte"> without the <p class="foot">.
I use this, but it's not ok, I have the class='Foot' in my result :
$crawler->filterXPath("//*[#id='Texte' and not(#class='Foot')]")->html();

Almost.
// correct
$crawler->filterXPath("//*[#id='Texte']/*[not(#class='Foot')]")->html();
// yours, for comparison
$crawler->filterXPath("//*[#id='Texte' and not(#class='Foot')]")->html();

select children of the first element of a certain class using XPath

i have this type of code:
<div class="content">
<p></p>
<p></p>
<p></p>
</div>
<div class="content">
<p></p>
<p></p>
<p></p>
</div>
i wish to select all p elements from the first element with the class content.
i managed to select the first class by using:
(//div[#class="content"])[1]
but using (//div[#class="content"])[1]/p it still shows both classes

Here's an working example using PHP's SimpleXML. I've made some small changes to the HTML code you provided so the output would be more meaningful.
Regarding the XPath expression you provided I just removed the parenthesis and it all worked as expected.
NOTE: Following #LarsH's comment, I reverted the XPath expression as it was OK for starters. I took the liberty to update it based on its example.
<?php
$html = <<<HTML
<body>
<div class="content">
<p>1</p>
<p>2</p>
<p>3</p>
</div>
<div class="content">
<p>4</p>
<p>5</p>
<p>6</p>
</div>
<div>
<div class="content">
<p>7</p>
<p>8</p>
<p>9</p>
</div>
</div>
</body>
HTML;
$sxe = new SimpleXMLElement($html);
foreach ($sxe->xpath('(//div[#class="content"])[1]/p') as $p) {
echo "$p\n";
}
Output:
1
2
3

Try using the id of your iframe element:
