And, as a small point, if one's work is confidential for the reason that it is so extremely useful/important/wonderful (!?!), while one cannot claim this directly, it is usually possible to communicate facts about the situation in a way that will be understood by potential employers. One's letter writers would hopefully/presumably comment on the situation, and possibly gossip will lead the way, besides, if it's really something good.

At least as a starting point, honesty + keeping promises is a good baseline. :)

I am fetching data from RSS feed with Magpie.
$rss[description]  contains CDATA with html elements:  

&lt;![CDATA[  
&lt;div&gt;  
 &lt;a href='url'&gt;  
  &lt;img src='img_url' alt='aaa' title='bbb' border='0' width='116' height='116'&gt;  
 &lt;/a&gt;  
&lt;/div&gt;]]&gt;  
Some other text  


How can I fetch "img_url" from this?  Is preg_match() the only way? Maybe I can use simpleXML?
