<div style="margin-top: 0px; padding-right: 5px;" class="lftFlt1">

    <a href="" onclick="setList1(157204);return false;" class="contentSubHead" title="USA USA">USA USA</a>
    <div style="display: inline; margin-right: 10px;"><a href="" onclick="rate('157204');return false;"><img src="http://icdn.raaga.com/3_s.gif" title="RATING: 3.29" style="position: relative; left: 5px;" height="10" width="60" border="0"></a></div>

You should use DOMDocument or XPath. RegEx is generally not recommended for parsing HTML.

Use regex:

/setList1\(([0-9]+)\)[^>]+title="([^"]+)"/si

and preg_match() or preg_match_all()

    Regex is not the way to parse HTML. See: http://stackoverflow.com/questions/1732348/regex-match-open-tags-except-xhtml-self-contained-tags/1732454#1732454 and other responses on that thread. –  Jul 30 '10 at 07:40

Please go through my previous answers about how to handle HTML with DOM.

XPath to get the Text Content of all anchor elements:

//a/text()

XPath to get the title attribute of all anchor elements:

//a/@title

XPath to get the onclick attribute of all anchor elements:

//a/@onclick

You will have to use some string function to extract the number from the onclick text.

By far the best lib for scraping is simple html dom. basically uses jquery selector syntax.

http://simplehtmldom.sourceforge.net/

The way you'd get the data in this example:

include("simple_html_dom.php");
$dom=str_get_html("page.html");
$text=$dom->find(".lftFlt1 a.contentSubHead",0)->plaintext;
//or 
$text=$dom->find(".lftFlt1 a.contentSubHead",0)->title;

  • That's your opinion. How many other libs have your tried? Suggested third party alternatives that actually use DOM instead of String Parsing: [phpQuery](http://code.google.com/p/phpquery/), [Zend_Dom](http://framework.zend.com/manual/en/zend.dom.html) and [FluentDom](http://www.fluentdom.org). – Gordon Jul 30 '10 at 07:57
  • ya it helped for me but one correction i changed the $dom=file_get_html("page.html"); can u please explain the .lftFlt1 a.contentSubHead this thing??? –  Jul 30 '10 at 08:05
  • @Ram it's a CSS Selector, which (contrary to steve's suggestion) is not a jQuery thing but a W3C standard: http://www.w3.org/TR/CSS2/selector.html – Gordon Jul 30 '10 at 08:14
  • ya ok.. but i am having more class with lftFlt1 in an webpage i used this code it didnt work $dom=file_get_html("http://www.raaga.com/channels/tamil/moviedetail.asp?mid=T0001923"); foreach($text=$dom->find(".lftFlt1 a.contentSubHead",0) as $a) { echo $a->plaintext; } –  Jul 30 '10 at 08:22
  • @Ram obviously. the second argument to `find` returns the nth-child. See the docs http://simplehtmldom.sourceforge.net/manual.htm – Gordon Jul 30 '10 at 08:36
  • $str = <<Kakha Kakha HTML; $d = str_get_html($str); foreach($d->find('a') as $e) echo $e->onClick.'
    '; this return null value i cannot get the value of on click???     –  Jul 30 '10 at 09:18

I did it this way

$a=$coll->find('div[class=lftFlt1]');
$text=$element->find("a[class=cursor]",0)->onclick;
