I’m performing a parse on a file html with the following structure :

<div class="lstImv blackBd12">
    <div class="stCl3 stLeft imvImg">
        <div class="imgBox">

Editing

The block to follow :

<div class="lstImv blackBd12"></div>

encompasses the other tags where the textContents target, it repeats itself a few times (in the example, after editing, I put only 2).

So through this code :

<?php
$html = "exemplo_parse.html";
libxml_use_internal_errors(true);
$dom = new domDocument('1.0', 'utf-8'); 
$dom->loadHTMLFile($html); 
$dom->preserveWhiteSpace = false; 
$xpath = new DOMXPath($dom);
$content = $xpath->query('//div[@class="lstImv blackBd12"]');
foreach($content as $span)
{
    echo "<pre>";
        print_r($span);
    echo "</pre>";
}
?>

I get 2 objects with the respective values :

DOMElement Object
(
    [tagName] => div
    [schemaTypeInfo] => 
    [nodeName] => div
    [nodeValue] => 











        Get_text 1

So the way I’m doing :

<?php
$html = "exemplo_parse.html";
libxml_use_internal_errors(true);
$dom = new domDocument('1.0', 'utf-8'); 
$dom->loadHTMLFile($html); 
$dom->preserveWhiteSpace = false; 
$xpath = new DOMXPath($dom);
$content = $xpath->query('//strong[@class="imvFse emp-fase"]');
foreach($content as $span)
{
    echo "Key 1 : ".$span->textContent."<br/>";
}
$content = $xpath->query('//strong[@class="emp-nome infNme colorTxt"]');
foreach($content as $span)
{
    echo "Key 2 : ".$span->textContent."<br/>";
}
$content = $xpath->query('//span[@class="emp-loc-part1 infLoc"]');
foreach($content as $span)
{
    echo "Key 3 : ".$span->textContent."<br/>";
}
$content = $xpath->query('//span[@class="emp-loc-part2 infLoc"]');
foreach($content as $span)
{
    echo "Key 4 : ".$span->textContent."<br/>";
}
$content = $xpath->query('//li[@class="txtBed emp-un-dorms"]');
foreach($content as $span)
{
    echo "Key 5 : ".$span->textContent."<br/>";
}
$content = $xpath->query('//li[@class="txtArea emp-un-area"]');
foreach($content as $span)
{
    echo "Key 6 : ".$span->textContent."<br/>";
}
$content = $xpath->query('//li[@class="txtCar emp-un-park"]');
foreach($content as $span)
{
    echo "Key 7 : ".$span->textContent."<br/>";
}
?>

I get the data this way :

Key 1 : Get_text 1
Key 1 : Other Get_text 1
Key 2 : 
Key 2 : 
Key 3 : Get_text 2
Key 3 : Other Get_text 2
Key 4 : Get_text 3
Key 4 : Other Get_text 3
Key 5 : Get_text 6
Key 5 : Other Get_text 6
Key 6 : Get_text 7
Key 6 : Other Get_text 7
Key 7 : Get_text 9
Key 7 : Other Get_text 9

Meaning she’s iterating on the keys, only that I would like the Keys to come sequentially(K1,K2,...,K7, K1,K2,...,K7) and not in the way it is (K1, K1,K2,K2...,K7,K7).

php xpath php-domxpath

  • You have two blocks with class lstImv blackBd12 and want to iterate on these blocks? Since you should only iterate on nodes children only those with classes emp and etc...?

  • That Marcelo, those who have the text...

  • And it needs to be ordered something like: [node-1][item-1] > Get_text 1 and [node-2][item-1] > Other Get_text 1. That’s right?

Yes, in the method query accepted as argument expressions, you can for example use the conditional OR for the classes you want to obtain:

$content = $xpath->query('//strong[@class="imvFse emp-fase" OR @class="emp-nome infNme colorTxt"]');

  • Marcelo thanks for the attention, I think my question is not yet in the way to express my real goal, I will be editing it for better understanding, I believe you will be able to show me the way...

  • Marcelo I edited, I apologize for not expressing myself as I wanted the first attempt, I appreciate if you can take a look again.

  • @Magichat checks the edited answer and if that’s what you’re trying to get.

  • Marcelo, thank you again: "only I would like the Keys to come sequentially(K1,K2,...,K7, K1,K2,...,K7) and not in the way it is (K1, K1,K2,K2...,K7,K7)". I appreciate the elegance of your code and I am sure that with small adjustments you can arrive at the expected result, it is certain that this must have occurred due to my lack of clarity, yet I’ll be posting the solution I’ve been trying to find and I’ll be waiting for the adjustments in yours to validate it as correct too... See through my solution the goal I was looking for. Vlw man ;)

  • @Magichat made the change. If the structure stays this way.

  • Top man, vlw the force...had already left my +1 ... The solution I was looking for was exactly this way that used... I need to study more this kind of interaction...
