WordPress.class.php

<?php


/**

class Wordpress

	public static $wpXML;

Thanks for this, it's been extremely useful, I had header been executed from my xml file must have been from the content wrapping the content in htmlentities solved that.

htmlentities($content->encoded) 

I also added a excerpt:

$excerpt = $item->children('http://wordpress.org/export/1.2/excerpt/');

Thank you!

Thank you! I've optimized it a bit, added tags and both tags and categories now return the display value as well. Also removed all SimpleXmlElements by type-casting to string:

    foreach ($xml->channel->item as $item) {
        $categories = array();
        $tags       = [];
        foreach ($item->category as $category) {
            if ($category['nicename'] != "uncategorized" && $category['domain'] == "category") {
                $categories[(string)$category['nicename']] = (string)$category;
            } elseif ($category['domain'] == 'post_tag') {
                $tags[(string)$category['nicename']] = (string)$category;
            }
        }

        $content = $item->children('http://purl.org/rss/1.0/modules/content/');

        $posts[] = array(
            "title"      => (string)$item->title,
            "content"    => (string)$content->encoded,
            "pubDate"    => new DateTime((string)$item->pubDate),
            "categories" => $categories,
            "tags"       => $tags,
            "slug"       => (string)$item->guid
        );
    }

@tricoos Wow I wrote this in 2013 I am surprised it still works!

Thank you for this. Yes, it's still working in 2019. Do you know how to parse the metadata from the XML as well? Thanks!

@cristianfx I am amazed this still works in 2019. Metadata could probably be parsed in a similar way.

Really cool function, thanks a lot!
