PHP Question

PHP get img src from xml

I have a page with xml that looks like:

<?xml version="1.0" encoding="UTF-8"?><rss version="2.0">
<title>FB-RSS feed for Salman Khan Fc</title>
<description>FB-RSS feed for Salman Khan Fc</description>
<managingEditor> (FB-RSS)</managingEditor>
<pubDate>31 Mar 16 20:00 +0000</pubDate>
<title>Photo - Who is the Best Khan ?</title>
<description>&lt;a href=&#34;;&gt;&lt;img src=&#34;;oe=57BB41D5&#34;&gt;&lt;/a&gt;&lt;br&gt;&lt;br&gt;Who is the Best Khan ?</description>
<pubDate>31 Mar 16 20:00 +0000</pubDate>
<description>&lt;a href=&#34;;&gt;&lt;img src=&#34;;oe=57778068&#34;&gt;&lt;/a&gt;&lt;br&gt;&lt;br&gt;</description>
<pubDate>31 Mar 16 19:58 +0000</pubDate>

I want to get the
s of the
s in the

The images are stored in the
however, they are not in the format of


they rather look like:

&lt;img src=&#34;https://scontent.xx.fbc...

is replace with
... I guess thats why
$imgs = $dom->getElementsByTagName('img');
returns nothing.

Is there any work around?

This is how I call it:

$dom = new DOMDocument();
$dom->loadXML( $xml_file);
$imgs = ...(get the imgs to extract the src...('img') ??;

//Then run a possible foreach
//something like:

foreach($imgs as $img){

$src= ///the src of the $img

//try it out
echo '<img src="'.$src.'" /> <br />',

Any Idea?


You have HTML embedded in XML tags, so you have to retrieve XML nodes, load each HTML and retrieve desired tag attribute.

In your XML there are different <description> nodes, so using ->getElementsByTagName will return more than your desired nodes. Use DOMXPath to retrieve only <description> nodes in the right tree position:

$dom = new DOMDocument();
libxml_use_internal_errors( True );
$dom->loadXML( $xml );
$dom->formatOutput = True;

$xpath = new DOMXPath( $dom );
$nodes = $xpath->query( 'channel/item/description' );

Then iterate all nodes, load node value in a new DOMDocument (no need to decode html entities, DOM already decodes it for you), and extract src attribute from <img> node:

foreach( $nodes as $node )
    $html = new DOMDocument();
    $html->loadHTML( $node->nodeValue );
    $src = $html->getElementsByTagName( 'img' )->item(0)->getAttribute('src');
