Implementation Reference
- src/handlers/crawl-handlers.ts:295-329 (handler)Main handler function that implements the parse_sitemap tool. Fetches sitemap XML directly using axios, extracts URLs from <loc> tags using regex, applies optional regex filter, limits output to first 100 URLs, and returns formatted text response.async parseSitemap(options: { url: string; filter_pattern?: string }) { try { // Fetch the sitemap directly (not through Crawl4AI server) const axios = (await import('axios')).default; const response = await axios.get(options.url, { timeout: 30000, headers: { 'User-Agent': 'Mozilla/5.0 (compatible; MCP-Crawl4AI/1.0)', }, }); const sitemapContent = response.data; // Parse XML content - simple regex approach for basic sitemaps const urlMatches = sitemapContent.match(/<loc>(.*?)<\/loc>/g) || []; const urls = urlMatches.map((match: string) => match.replace(/<\/?loc>/g, '')); // Apply filter if provided let filteredUrls = urls; if (options.filter_pattern) { const filterRegex = new RegExp(options.filter_pattern); filteredUrls = urls.filter((url: string) => filterRegex.test(url)); } return { content: [ { type: 'text', text: `Sitemap parsed successfully:\n\nTotal URLs found: ${urls.length}\nFiltered URLs: ${filteredUrls.length}\n\nURLs:\n${filteredUrls.slice(0, 100).join('\n')}${filteredUrls.length > 100 ? '\n... and ' + (filteredUrls.length - 100) + ' more' : ''}`, }, ], }; } catch (error) { throw this.formatError(error, 'parse sitemap'); } }
- Zod schema defining input validation for parse_sitemap tool: requires a valid URL string, optional filter_pattern regex string.export const ParseSitemapSchema = createStatelessSchema( z.object({ url: z.string().url(), filter_pattern: z.string().optional(), }), 'parse_sitemap', );
- src/server.ts:875-878 (registration)Tool call handler registration in the switch statement: validates args with ParseSitemapSchema and delegates to crawlHandlers.parseSitemap.case 'parse_sitemap': return await this.validateAndExecute('parse_sitemap', args, ParseSitemapSchema, async (validatedArgs) => this.crawlHandlers.parseSitemap(validatedArgs), );
