Getting Started

Basic example

Returns an list of URLs only.

use vipnytt\SitemapParser;
use vipnytt\SitemapParser\Exceptions\SitemapParserException;

try {
    $parser = new SitemapParser();
    $parser->parse('http://php.net/sitemap.xml');
    foreach ($parser->getURLs() as $url => $tags) {
        echo $url . '<br>';
    }
} catch (SitemapParserException $e) {
    echo $e->getMessage();
}

Advanced

Returns all available tags, for both Sitemaps and URLs.

use vipnytt\SitemapParser;
use vipnytt\SitemapParser\Exceptions\SitemapParserException;

try {
    $parser = new SitemapParser('MyCustomUserAgent');
    $parser->parse('http://php.net/sitemap.xml');
    foreach ($parser->getSitemaps() as $url => $tags) {
        echo 'Sitemap<br>';
        echo 'URL: ' . $url . '<br>';
        echo 'LastMod: ' . $tags['lastmod'] . '<br>';
        echo '<hr>';
    }
    foreach ($parser->getURLs() as $url => $tags) {
        echo 'URL: ' . $url . '<br>';
        echo 'LastMod: ' . $tags['lastmod'] . '<br>';
        echo 'ChangeFreq: ' . $tags['changefreq'] . '<br>';
        echo 'Priority: ' . $tags['priority'] . '<br>';
        echo '<hr>';
    }
} catch (SitemapParserException $e) {
    echo $e->getMessage();
}

Recursive

Parses any sitemap detected while parsing, to get an complete list of URLs

use vipnytt\SitemapParser;
use vipnytt\SitemapParser\Exceptions\SitemapParserException;

try {
    $parser = new SitemapParser('MyCustomUserAgent');
    $parser->parseRecursive('http://www.google.com/robots.txt');
    echo '<h2>Sitemaps</h2>';
    foreach ($parser->getSitemaps() as $url => $tags) {
        echo 'URL: ' . $url . '<br>';
        echo 'LastMod: ' . $tags['lastmod'] . '<br>';
        echo '<hr>';
    }
    echo '<h2>URLs</h2>';
    foreach ($parser->getURLs() as $url => $tags) {
        echo 'URL: ' . $url . '<br>';
        echo 'LastMod: ' . $tags['lastmod'] . '<br>';
        echo 'ChangeFreq: ' . $tags['changefreq'] . '<br>';
        echo 'Priority: ' . $tags['priority'] . '<br>';
        echo '<hr>';
    }
} catch (SitemapParserException $e) {
    echo $e->getMessage();
}

Parsing of line separated text strings

Note: This is disabled by default to avoid false positives when expecting XML, but fetches plain text instead.

To disable strict standards, simply pass this configuration to constructor parameter #2: ['strict' => false].

use vipnytt\SitemapParser;
use vipnytt\SitemapParser\Exceptions\SitemapParserException;

try {
    $parser = new SitemapParser('MyCustomUserAgent', ['strict' => false]);
    $parser->parse('https://www.xml-sitemaps.com/urllist.txt');
    foreach ($parser->getSitemaps() as $url => $tags) {
            echo $url . '<br>';
    }
    foreach ($parser->getURLs() as $url => $tags) {
            echo $url . '<br>';
    }
} catch (SitemapParserException $e) {
    echo $e->getMessage();
}

Configuration

Available configuration options, with their default values:

$config = [
    'strict' => true, // (bool) Disallow parsing of line-separated plain text
    'guzzle' => [
        // GuzzleHttp request options
        // http://docs.guzzlephp.org/en/latest/request-options.html
    ],
];
$parser = new SitemapParser('MyCustomUserAgent', $config);

If an User-agent also is set using the GuzzleHttp request options, it receives the highest priority and replaces the other User-agent.
