在网页中刮表？

I'm currently trying to scrape all the results from a table within a webpage. At the moment I'm attempting it with file_get_contents() and some jquery but I'm unable to seem to find the selectors within the DOM with jQuery.

I'm trying to get them row by row as I intend on inserting them into my database for future use.

My question is how would I get the values of each <td> within each <tr> within the table on the webpage in order to insert all of these values into my database?

PHP:

Controller

function scqf_stats(){

    $data['stats'] = file_get_contents("http://www.scqf.org.uk/Search%20The%20Database?ssub=&stit=Enter+a+title+or+a+part+of+it&sown=Start+typing+and+select+from+dropdown&sownid=&slev=&scrb=&sk=&submitsp=Search");
    $data['main_content'] = 'alt_test';

    $this->load->view('templates/single_view', $data);

}

View

<pre>

<script src="<?php echo base_url() ?>js/scrape.js"></script>

<?php print_r($stats); ?>

</pre>

jQuery:

$(document).ready(function() {

function scrape_it(){

    $('#search-database-results').children('tbody').children('tr').each(function (){
        $this = $(this);

        $('tr').children('td').each(function() {

            var text = $('td').text();
            console.log(text);

        });   

    });

}

scrape_it();

});

Assuming you have the scraped page in an element of id=search-database-results this should do to find all TDs within each TR within the table (in order):

$(document).ready(function() {
    function scrape_it(){
        $('#search-database-results tr td').each(function() {
            var text = $(this).text();
            console.log(text);
        });
    }
    scrape_it();
});

If you need more/different, please explain in more detail.
