I have been manually placing my Master badges from Code School onto my blog which, being a WordPress blog, runs on PHP. I don’t have the script running that shows the fraction completed on Paths that I haven’t yet mastered, but I can get the ones that I’ve completed.
The PHP script I’ve built so far is below. Due to some CSS I want to change, I haven’t implemented it yet. But I can say that it does indeed scrape the page. The jQuery required to display it in the sidebar I’ll share once I get the CSS issues worked out. This is very similar to the code I used to get the CodeEval profile, but it’s been refactored and modified for use with the Code School page.
<?php
function getClass($classname, $htmltext)
{
$dom = new DOMDocument;
$dom->loadHTML($htmltext);
$xpath = new DOMXPath($dom);
$results = $xpath->query("//*[@class='" . $classname . "']");
return $results;
}
function buildContent($results)
{
$content = "";
foreach ($results as $node) {
$partial_content = innerHTML($node);
$content = $content . $partial_content;
}
return $content;
}
/* this function preserves the inner content of the scraped element.

{
$doc = new DOMDocument();
foreach ($node->childNodes as $child) {
$doc->appendChild($doc->importNode($child, true));
}
return $doc->saveHTML();

$previous_value = libxml_use_internal_errors(TRUE);

/* return the html */
echo $full_content;

</div>
