Webscrape plugin

I have scrape in action here using the wp web scraping plugin written by Akshay.

Looking into the ‘phpquery one file’ code on google (basis of the plugin), I find in the markup function, approx. line 700, towards the end of the domdocumentwrapper class the following loop:

foreach($nodes as $i => $node)
if ($node->isSameNode($this->root)) {
//	var_dump($node);
$nodes = array_slice($nodes, 0, $i)
+ phpQuery::DOMNodeListToArray($node->childNodes)
+ array_slice($nodes, $i+1);
}

Looking at my scrape example again (see link above), there are no line breaks of the scraped sports website.
However, in the above function there is no echo. How can I manage to use the wp scraper plugin with line breaks?

Furthermore I never saw “+” in php for concatenation, only the dot.

Thanks.
