Sitemap

var nodes = new List<SitemapNode> { new ("https://example.com/page.html") };
var sitemap = new Sitemap(nodes);
var service = new SitemapService(new XmlSerializer());
var xmlResult = service.Serialize();

Sitemap index

var sitemapIndexNodes = new List<SitemapIndexNode> { new("https://example.com/sitemap-1.xml") };
var sitemapIndex = new SitemapIndex(sitemapIndexNodes);
var service = new SitemapIndexService(new XmlSerializer());
var xmlResult = service.Serialize();

Dependency injection

// DI setup
services.AddDefaultSitemapServices();

// implementation
public class MyClass()
{
    public MyClass(ISitemapService service)
    {
        var nodes = new List<SitemapNode> { new ("https://example.com/page.html") };
        var sitemap = new Sitemap(nodes);
        var xmlResult = service.Serialize();
    }
}    

Working with relative URLs

public class MyBaseUrlProvider : IBaseUrlProvider
{
    public Uri BaseUrl => new ("https://example.com", UriKind.Absolute);
}

// DI setup
services.AddBaseUrlProvider<MyBaseUrlProvider>();
services.AddDefaultSitemapServices();
// or in one function:
services.AddDefaultSitemapServices<MyBaseUrlProvider>();

// regular setup
var serializer = new XmlSerializer(new MyBaseUrlProvider());
var service = new SitemapService(serializer);

// nodes, relative urls
var nodes = new List<SitemapNode> { new ("page.html") };

Stylesheets

XSLT stylesheets for sitemaps and sitemap indexes are supported. The stylesheet can be added to the Sitemap or SitemapIndex object:

var sitemap = new Sitemap(nodes, "my-stylesheet.xslt");

For more information, see Sitemap Style.

Deserialization

It is possible to load existing XML and deserialize it into a sitemap object:

var xml = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><urlset> ....";
var serializer = services.GetRequiredService<ISitemapSerializer>();
var sitemap = serializer.Deserialize(xml);
