Having trouble parsing HTML with PHP and Simple HTML DOM

I am in the process of trying to parse HTML with simple_html_dom.php. The HTML I am trying to parse is shown below. I can successfully grab each product name: Product 1, Product 2, Product 3, etc.

I would also like to grab the itemprice_0 from each product. This is where I am running into issues. Here is my code:

<?php
require_once 'simple_html_dom.php';

$html = file_get_html('https://www.webaddress.com');

foreach($html->find('span.productName') as $e)
echo $e.'<br />'; //successfully displays all product names

foreach($html->find('#itemprice_0') as $e)
echo $e; //doesn't display the item prices

foreach($html->find('.dollar') as $e)
echo $e; //doesn't display the dollar amounts
?>

Here is the HTML: 

<span class="productName">Product 1</span>  

<p class="price">
<strike>
<span class="dollar-symbol">$</span>  
<span class="dollar">15</span><span class="dot">.</span>  
<span class="cents">99</span></strike>
</p>  

<p class="salePrice" id='itemprice_0'>  
<span class="dollar-symbol">$</span>  
<span class="dollar">13</span><span class="dot">.</span>  
<span class="cents">99</span>  
</p>

You can use the following solution to solve your problem:

$domd=@DOMDocument::loadHTML($html);
$xp=new DOMXPath($domd);
foreach($xp->query('//*[contains(@class,"dollar")]') as $e)
var_dump($e->textContent);

I accessed the salePrice class and echoed out the dollar amount. 

foreach($html->find('span.productName') as $e)
    echo $e.'<br />'; //successfully displays all product names

foreach($html->find('p.price') as $e)
    $e = str_replace(' ', '', $e);
    echo 'Regular Price: ' . $e;

foreach($html->find('p.salePrice') as $e)
    $e = str_replace(' ', '', $e);
    echo 'Sale Price: ' . $e;

I also removed whitespaces.

Result:

Product 1
Regular Price: $15.99
Sale Price: $13.99

I also made the loop look for the itemprice_0 id only, and got the same result: 

foreach($html->find('p[id=itemprice_0]') as $e)
$e = str_replace(' ', '', $e);
echo 'Sale Price: ' . $e;

Same Result: 

Product 1
Regular Price: $15.99
Sale Price: $13.99

Is this what you were looking for?

itemprice_0 is unique, if you want to select more than one element you should use class selector. In simple_html_dom you can fetch nested elements like this(didn't test it):

<?php
require_once 'simple_html_dom.php';

foreach($html->find('.salePrice') as $prices){
    echo $price->find('.dollor')->plaintext;
    echo $price->find('.cents')->plaintext;
}
