Question

I am trying to extract the src value from a tag,
so far I seem to be able to extract the string between the src value and the final quotation mark in the string

String:

<img  border="0"  src="http://i.bookfinder.com/about/booksellers/logo_borderless/amazon_uk.gif" width="89" height="31" alt="">

e.g. in PHP:

preg_match('/src=\"(.*)\"/', $row->find('a img',0), $matches);
if($matches){
   echo $matches[0];
}

prints out
src="http://i.bookfinder.com/about/booksellers/logo_borderless/amazon_uk.gif" width="89" height="31" alt=""

but what i really want printed is…
src="http://i.bookfinder.com/about/booksellers/logo_borderless/amazon_uk.gif"

or if possible just…
http://i.bookfinder.com/about/booksellers/logo_borderless/amazon_uk.gif

what should I be adding to the regex? Thanks

For RegExp:

preg_match('/src="([^"]+)"/', $row->find('a img',0), $matches);
echo $matches[1];

If i’m right, you are working with simple_html_dom_parser library. If that’s true you can just type:

$row->find('a img',0)->src
