Is it possible to parse sitemap from local file?

[Jan-Petter Gundersen]

Yes, that's possible.

Just add the contents of the file as the second parameter of parse(). The URL is still required to determine filetype, but won't be crawled.

Example:

$parser = new SitemapParser();
$parser->parse('https://example.com/sitemap.xml', 'INSERT_FILE_CONTENTS_HERE');
foreach ($parser->getURLs() as $url => $tags) {
    echo $url . '<br>';
}
