How can I only get the alt attribute of the a p tag in PHP?

Question

I\'m working on a script that echo\'s only the price. If I do:

$alttag = $oNode[\'p\'];
echo $alttag;

It will echo everything in <

So is this basically a web crawler for prices? I would suggest you look into using PHP's DOMDocument library to parse XML (Which XHTML practically is). You could then do something like:

//create a new DOMDocument object
$xmlDoc = new DOMDocument();  
//load your html for parsing
$xmlDoc->loadHTML("Your HTML Code
");
//select the element that you want the attribute from...you may need to use $xmlDoc->getElementsByTagName('p');
$p_element = $xmlDoc->getElementById('yourtag');
//get the attribute alt of the selected element
$alt = $p_element->getAttribute('alt');
//show alt attribute value
echo $alt;

This is just pseudo code and will not solve your problem, however it seems to be a better solution than the parser you are trying to use. Look at these links for more information (I hope this helps):
