Extract html code from a page with PHP to extrapolate some images - php

Question

I've to create a PDF document from a product details page of my WP site and I've extract all html code from the page to extrapolate img and table tag.
I installed a plugin to create a PDF document from a page but imagese and tables are not inserted: only the text is inserted into the document.
The plugin is woocommercePrintProduct and I've edited its code to insert images into PDF document also. The function that should be modified is the following:
div class="descrizione" style="margin:0 30px;">
<div class="colonnaSx" style="float:left;width:350px;margin-right:30px">
<div class="pacchettino">
<?php if( get_field('descrizione_prod') ): ?>
<h3>DESCRIPTION</h3>
<p><?php the_field('descrizione_prod'); ?></p>
<?php endif; ?>
</div>
<div class="pacchettino">
<?php if( get_field('forma') ): ?>
<h3>SHAPE</h3>
<p><?php the_field('forma'); ?></p>
<?php endif; ?>
</div>
<div class="pacchettino">
<?php if( get_field('posa') ): ?>
<h3>INSTALLATION</h3>
<p><?php the_field('posa'); ?></p>
<?php endif; ?>
</div>
<div class="pacchettino">
<?php if( get_field('conduttore') ): ?>
<h3>CONDUCTOR</h3>
<p><?php the_field('conduttore'); ?></p>
<?php endif; ?>
</div>
<div class="pacchettino">
<?php if( get_field('isolante') ): ?>
<h3>INSULATION</h3>
<p><?php the_field('isolante'); ?></p>
<?php endif; ?>
</div>
<div class="pacchettino">
<?php if( get_field('guaina') ): ?>
<h3>SHEAT</h3>
<p><?php the_field('guaina'); ?></p>
<?php endif; ?>
</div>
<div class="pacchettino">
<?php if( get_field('sforzo_massimo_di_tiro') ): ?>
<h3>MAX MECHANICAL STRESS</h3>
<p><?php the_field('sforzo_massimo_di_tiro'); ?></p>
<?php endif; ?>
</div>
<div class="pacchettino">
<?php if( get_field('guainetta') ): ?>
<h3>INTERNAL SHEATH</h3>
<p><?php the_field('guainetta'); ?></p>
<?php endif; ?>
</div>
</div>
<div class="colonnaDx" style="float:right;width:350px;">
<div class="pacchettino">
<?php if( get_field('marchiatura') ): ?>
<h3>MARCHIATURA</h3>
<p><?php the_field('marchiatura'); ?></p>
<?php endif; ?>
</div>
<div class="pacchettino">
<?php if( get_field('colore') ): ?>
<h3>COLORE</h3>
<p><?php the_field('colore'); ?></p>
<?php endif; ?>
</div>
<div class="pacchettino">
<?php if( get_field('tensione_di_esercizio') ): ?>
<h3>TENSIONE DI ESERCIZIO</h3>
<p><?php the_field('tensione_di_esercizio'); ?></p>
<?php endif; ?>
</div>
<?php /*
<table class="description">
<?php
$description = wpautop($this->data->description);
$description = preg_replace("/\[[^\]]+\]/", '', $description);
$description = explode('<p>', $description);
foreach ($description as $value) {
?>
<tr>
<td style="padding-bottom: 20px;">
<?php echo $value ?>
</td>
</tr>
<?php
}
?>
</table>
*/
?>
<div class="description" style="margin:0 30px;">
<?php
$description = wpautop($this->data->description);
$description = preg_replace("/\[[^\]]+\]/", '', $description);
$description = explode('<p>', $description);
foreach ($description as $value) {
?>
<div class="pacchettino" style="padding-bottom: 20px;margin:0 30px;">
<?php
echo $value
?>
</div>
<?php
}
?>
</div>
<?php
return ob_get_clean();
}
I thought to extract html code from the details product page and then, extrapolate img tag and intert them into the document.
Can you help me, please?
