sample $embed_html

chrisjdavis · 2017-04-12T15:57:01Z

This is what I was advocating. Ugly, but seems to work.

$dom = new DOMDocument;
$dom->loadHTML( $embed_html );
$nodelinks = $dom->getElementsByTagName('a');

$links = iterator_to_array($nodelinks);

$count = count( $links );
$i = 0;

foreach ( $links as $link ) $i++; {
	if( $i == $count ) {
		$link->setAttribute("class", "u-url");
	}
};

$embed_html = $dom->saveHTML();

Updating the gist to include LIBXML_HTML_NOIMPLIED to the loadHTML so the saveHTML doesn't include the <html><body> tags.

@chrisjdavis works like a charm

To re-iterate my comment on Twitter, this isn't mission critical work, just an itch I wanted to scratch, but at some point would like to understand why the if (end($links)) didn't work.

give this a try:

	// Set my DOM.
	$dom = new DOMDocument;
	$dom->loadHTML( $embed_html );

	// Set my XPath lookup.
	$xpath = new DOMXPath( $dom );
	$links = $xpath->evaluate( '//a' );

	// Bail if I don't have any links.
	if ( empty( $links->length ) || absint( $links->length ) < 1 ) {
		return;
	}

	// Get the count of my last link.
	$last  = absint( $links->length ) - 1;

	// Set my last item.
	$item = $links->item( $last );

	// Set the class on my last item.
	$item->setAttribute( 'class', 'u-url' );

	// Save the HTML back to the DOM.
	$html = $dom->saveHTML();
