When `load_all_paths=True`, the loader parses XML sitemaps and requires the `lxml` package to be installed (`pip install lxml`).

Args: web_page: The web page to load or the starting point from where relative paths are discovered. load_all_paths: If set to True, all relative paths in the navbar are loaded instead of only `web_page`. Requires `lxml` package. base_url: If `load_all_paths` is True, the relative paths are appended to this base url. Defaults to `web_page`. content_selector: The CSS selector for the content to load. Defaults to "main". continue_on_failure: whether to continue loading the sitemap if an error occurs loading a url, emitting a warning instead of raising an exception. Setting this to True makes the loader more robust, but also may result in missing data. Default: False show_progress: whether to show a progress bar while loading. Default: True sitemap_url: Custom sitemap URL to use when load_all_paths is True. Defaults to "{base_url}/sitemap.xml". allowed_domains: Optional set of allowed domains to fetch from. If None (default), the loader will restrict crawling to the domain of the `web_page` URL to prevent potential SSRF vulnerabilities. Provide an explicit set (e.g., {"example.com", "docs.example.com"}) to allow crawling across multiple domains.
