### Sitemap Support

```java
// Enable sitemap processing
container.singleton("sitemapsRule", SitemapsRule.class, rule -> {
    rule.addRule("url", ".*sitemap.*");
});

// Add sitemap URL
crawler.addUrl("https://example.com/sitemap.xml");
```

## Data Access and Storage

### Accessing Crawled Data

```java

                .<SitemapsRule> singleton("sitemapsRule", SitemapsRule.class, rule -> {
                    rule.setResponseProcessor(container.getComponent("sitemapsResponseProcessor"));

                    rule.addRule("url", ".*sitemap.*");
                })//
