how to find all <p> tags under heading - html

Question

I have to extract data from this link: http://bit.ly/l1rF5x
What I want to do is that I want to extract all p tags which comes under the <a> tag having attribute rel="bookmark". My only requirement is that only <p> tags which comes under this heading should be parsed, and remaining should be left as it is. Like for example in this page which I have given you, all <p> tags which comes under heading "IIFT question paper 2006", should be parsed.
help please.

Answer 1

You can try using the following :
$(function(){
var results= '';
$('a[rel="bookmark"] p').each(function(i,e){
results += $(e).html() + "\n";
});
alert(results);
});
Variable results will be alerted with the required content.

Answer 2

Since you haven't provided any information about the language / environment you want to use to extract this information, I've gone ahead and hacked something together with jQuery.
(Updated) You can see it in action here: JS Fiddle.
If you wanted to use PHP, I recommend simplehtmldom
Here is an example using simplehtmldom:
$url = 'http://school-listing.mba4india.com/page/7/';
$html = file_get_html($url);
$data = array();
// Find all anchors with the desired rel attribute
foreach ($html->find('a[rel="bookmark"]') as $a) {
$h4 = $a->parent(); // Get the anchors parent (in this case an h4)
// We're assuming the next sibling is a p tag here - should test for this here
$p = $h4->next_sibling();
$content = '';
// Iterate over all following p tags, until we run out of siblings or find one
// that isn't a p tag
while ($p) {
$content .= (string) $p;
if ($p->next_sibling() && $p->next_sibling()->tag == 'p') {
$p = $p->next_sibling();
} else {
break;
}
}
$data[] = array('h4' => $h4, 'content' => $content);
}
$br = '<br/>';
foreach ($data as $datum) {
echo $datum['h4'] . $br . $datum['content'];
echo $br.$br;
}
