Editing html using Simple_html_dom.php
Question
I am working through using simple_html_dom.php to scrape and edit/manipulate the following:
<?php
include('simple_html_dom.php');
$_GET["name"];
$html_code="https://hwb.wales.gov.uk/Home/Pages/Home.aspx";
$html_code= $html_code.$name."/?lang=en";
echo $html_code;
$html = file_get_html($html_code);
echo "<html>";
echo "<head>";
echo "<meta charset='UTF-8'>";
echo "<title>PHP Test</title>";
echo " </head>";
echo " <body>";
foreach($html->find('#LatestNewsArts') as $e)
// Code here to append hwb.wale.gov.uk to <img src="/ >
echo $e->innertext . '<br>';
echo " </body>";
echo "</html>";
?>
I can extract the <div> that I'm looking for - and echo it -- that works fine.
Where I hit a wall (my .php-fu is letting me down) is how to I intercept and edit the html inside the e$ that I have scraped?
What I am looking to do, is replace the <img src="/...."> tag with <img src="hwb.wales.gov.uk/....">

Setting a new value to an attribute can easily be done like this: $elmt->attribute = NewValue
Here's a working code answering your question:
// includes Simple HTML DOM Parser
include "simple_html_dom.php";
$html_code="https://hwb.wales.gov.uk/Home/Pages/Home.aspx";
// => I dont know what $name stands fore... It's up to you to change this code to suit your needs
//$html_code= $html_code.$name."/?lang=en";
echo $html_code;
$html = file_get_html($html_code);
echo "<html>";
echo "<head>";
echo "<meta charset='UTF-8'>";
echo "<title>PHP Test</title>";
echo " </head>";
echo " <body>";
// Loop through all divs with id="Article"
foreach($html->find('#LatestNewsArts #Article') as $e){
$url = "https://hwb.wales.gov.uk" . $e->find("img",0)->src;
// Set src to the new $url
$e->find("img",0)->src = $url;
// Print the outertext
echo $e->outertext . '<br>';
}
echo " </body>";
echo "</html>";
// Clear dom object
$html->clear();
unset($html);
