    <p>What I would like to do: get the text headline from the top post on <a href="http://reddit.com/r/worldnews" rel="nofollow">http://reddit.com/r/worldnews</a> and output it to a webpage of mine that will only have that text on it. </p> <p>In the end, I would like to grab the text from that webpage that I made using AppleScript cURL and output it.</p> <p>I am making a script that when I click the button it will tell me the top post.</p> <p><em>edit</em> If you can think about any way, I would like to do the same thing, but for Facebook notifications.</p> <p><em>edit</em> I have PHP grabbing the site and outputting here: <a href="http://colejohnsoncreative.com/personal/ai/worldnews.php" rel="nofollow">http://colejohnsoncreative.com/personal/ai/worldnews.php</a> This is the code that I am using:</p> <pre><code> &lt;?php // Get a file into an array. In this example we'll go through HTTP to get // the HTML source of a URL. $lines = file('http://www.reddit.com/r/worldnews'); // Loop through our array, show HTML source as HTML source; and line numbers too. foreach ($lines as $line_num =&gt; $line) { echo "Line #&lt;b&gt;{$line_num}&lt;/b&gt; : " . htmlspecialchars($line) . "&lt;br /&gt;\n"; } // Another example, let's get a web page into a string. See also file_get_contents(). $html = implode('', file('http://www.example.com/')); // Using the optional flags parameter since PHP 5 $trimmed = file('somefile.txt', FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES); ?&gt; </code></pre> <p>So I get all of the site's code to output, but all I need for the project is </p> <pre><code>&lt;a class="title " href="http://www.dailymail.co.uk/news/article-2219477/Cannabis-factory-couple-gave-400-000-drug-dealing-fortune-poor-Kenyans-jailed-years.html" &gt;British couple who spent most of the money they made from canabis growing on paying for life changing operations and schooling for people in a poor Kenyan village gets sent to prison for 3 years.&lt;/a&gt; </code></pre> <p>and everything else I need to throw away, how can I do that?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
