    <p>I'm writing a function that fishes out the src from the first image tag it finds in an html file. Following the instructions in <a href="https://stackoverflow.com/questions/138313/how-to-extract-img-src-title-and-alt-from-html-using-php">this thread</a> on here, I got something that seemed to be working:</p> <pre><code>preg_match_all('#&lt;img[^&gt;]*&gt;#i', $content, $match); foreach ($match as $value) { $img = $value[0]; } $stuff = simplexml_load_string($img); $stuff = $stuff[src]; return $stuff; </code></pre> <p>But after a few minutes of using the function, it started returning errors like this:</p> <blockquote> <p>warning: simplexml_load_string() [0function.simplexml-load-string0]: Entity: line 1: parser error : Premature end of data in tag img line 1 in path/to/script on line 42.</p> </blockquote> <p>and </p> <blockquote> <p>warning: simplexml_load_string() [0function.simplexml-load-string0]: tp://feeds.feedburner.com/~f/ChicagobusinesscomBreakingNews?i=KiStN" border="0"> in path/to/script on line 42.</p> </blockquote> <p>I'm kind of new to PHP but it seems like my regex is chopping up the HTML incorrectly. How can I make it more "airtight"?</p>

    1. COI'm not sure what's up, but the debugger in me is saying: Replace the xml_load calls with echo $img Also, it looks like you're overwriting $img with the LAST value every time you iterate in the foreach loop. Printing some debug statments might help clarify that, too.

    2. COWhat HTML are you feeding in and what's the value of $img when the warning is thrown?

    3. COIt would be very helpful to see the html you're passing into this. You might also consider printing out $img to make sure the regex patter is doing its job before it goes into simplexml.

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.
