Question

I have an embeddeble code of a slide like below. this whole html is stored in a variable $embed_code.

I am printing this code in PHP. Now I want a piece of code from this HTML string.

The code is written below. I want the code between <object> tag only.

$embed_code = '
 <div style="width:425px" id="__ss_617490"><strong style="display:block;
 margin:12px 0 4px"><a href="http://www.slideshare.net/al.capone/funny-beer-babies-
 enginnering-rev-2-presentation" title="Funny beer babies enginnering rev. 
 2">Funny beer babies enginnering rev. 2</a></strong>


<object id="__sse617490" 
 width="425" height="355"><param name="movie" value="http://static.slidesharecdn.com
/swf/ssplayer2.swf?doc=becoming-an-engineer-1222340701618958-9&stripped_title=funny-  
 beer-babies-enginnering-rev-2-presentation&userName=al.capone" /><param  
 name="allowFullScreen" value="true"/><param name="allowScriptAccess" value="always"/>
 <embed name="__sse617490" src="http://static.slidesharecdn.com/swf/ssplayer2.swf?doc=
  becoming-an-engineer-1222340701618958-9&stripped_title=funny-beer-babies-enginnering-
  rev-2-presentation& userName=al.capone" type="application/x-shockwave-flash" 
   allowscriptaccess="always" allowfullscreen="true" width="425" height="355"></embed> 
  </object>




 <div style="padding:5px 0  12px">View more<a href="http://www.slideshare.net
  /"> presentations</a> from <a href="http://www.slideshare.net/al.capone">
  al.capone</a>.</div></div>';

Now I want this string only from <object id="....." to "</embed> </object> this whole HTML is generated dynamically so give me any idea for this.

How can I do this? Is there any PHP function that can extract html between of any tag?

Answer 1

Use the DOMDocument classes.

$dom = new DomdDocument ();
$dom -> loadHtml ($embed_code);
$htmlObject = $dom -> getElementById ('__sse617490'); // Returns a DomElement
