I once answered it but I don't find the answer any longer.

If you take a look at the string (simplified/beautified):

<content:encoded><![CDATA[
    <p>Lorem Ipsom</p>
    <p>
      <a href='laura-bertram-trance-gemini-145-1080.jpg' 
         title='&lt;br&gt;November 2012 calendar from 5.10 The Test&lt;br&gt; &lt;a href=&quot;</a>
    </p>]]>
</content:encoded>

You can see that you have HTML encoded inside the node-value of the <content:encoded> element. So first you need to obtain the HTML value, which you already do:

$html = $boo->children('content', true)->encoded;

Then you need to parse the HTML inside $html. With which libraries HTML parsing can be done with PHP is outlined in:

If you decide to use the more or less recommended DOMDocument for the job, you only need to get the attribute value of a certain element:

Or for its sister library SimpleXML you already use (so this is more recommended, see as well the next section):

In context of your question here the following tip:

You're using SimpleXML. DOMDocument is a sister-library, meaning you can interchange between the two so you don't need to learn a full new library.

For example, you can use only the HTML parsing feature of DOMDocument, but import it then into SimpleXML. This is useful, because SimpleXML does not support HTML parsing.

That works via simplexml_import_dom().

A simplified step-by-step example:

// get the HTML string out of the feed:
$htmlString = $boo->children('content', true)->encoded;

// create DOMDocument for HTML parsing:
$htmlParser = new DOMDocument();

// load the HTML:
$htmlParser->loadHTML($htmlString);

// import it into simplexml:
$html = simplexml_import_dom($htmlParser);

Now you can use $html as a new SimpleXMLElement that represents the HTML document. As your HTML chunks did not have any <body> tags, according to the HTML specification, they are put inside the <body> tag. This will allow you for example to access the href attribute of the first <a> inside the second <p> element in your example:#

// access the element you're looking for:
$href = $html->body->p[1]->a['href'];

Here the full view from above (Online Demo):

// get the HTML string out of the feed:
$htmlString = $boo->children('content', true)->encoded;

// create DOMDocument for HTML parsing:
$htmlParser = new DOMDocument();

// your HTML gives parser warnings, keep them internal:
libxml_use_internal_errors(true);

// load the HTML:
$htmlParser->loadHTML($htmlString);

// import it into simplexml:
$html = simplexml_import_dom($htmlParser);

// access the element you're looking for:
$href = $html->body->p[1]->a['href'];

// output it
echo $href, "\n";

And what it outputs:

    I'd add just one thing: for sanity later, add an explicit `(string)` cast in `$htmlString = (string)$boo ...` and `$href = (string)$html ...`. I find the mental overhead of always adding it when not needed is less than the overhead of debugging those cases where it was needed but you didn't realise. – IMSoP Apr 07 '13 at 22:44
  • @IMSoP: You never need it in something called string context in PHP. It's good to know about it even apart from SimpleXML alone. E.g. with `echo` it's always not necessary. – hakre Apr 07 '13 at 23:40
  • @hakre :this is work when i run on html file,but this code i applied to in my php file i am getting error in-> notice: Undefined variable: htmlString in E:\Work Space\xampp\htdocs\Xml-Paser\note1.php on line 20 Notice: Undefined variable: htmlParser in E:\WorkSpace\xampp\htdocs\Xml-Paser\note1.php on line 30 – user2249819 Apr 08 '13 at 05:19
  • @user2249819: Insert it at the right place in your file. As you can see with my example, I don't have any loop: http://eval.in/15171 – hakre Apr 08 '13 at 07:27
  • @hakre Yes, I know. But like I said, I find it easier to always cast than remember which functions will do it automatically. Assigning to a variable can be especially problematic, as a non-string context call could happen dozens of lines later. – IMSoP Apr 08 '13 at 07:47
  • Sure, both ways are applicable. I normally don't care until I know I need string values. Then I can turn them into those. But the magic with SimpleXML is cause of many questions on SO, so it's good to educate this. – hakre Apr 08 '13 at 07:53

you would need to parse the image url eg via preg_match and this regex '(http://(?:[^']*))'
