在自建網站中顯示第三方 RSS 源（XML 格式）的內容，實現訂閱聚合。
回答中提到的方法：定義 DTD + `` 或 ``/`<object>`。</p><ul><li><strong>跨域限制</strong>：現代瀏覽器嚴格執行同源策略，直接加載外部 XML 會被攔截（CORS 錯誤）。</li><li><strong>XSS 風險</strong>：RSS 內容可能包含 `<script>`、`onload` 等惡意代碼，若直接渲染導致跨站腳本攻擊。</li><li><strong>DTD 方法已過時</strong>：IE 專有，Chrome/Firefox 不支持。</li></ul><h2>最佳實踐建議</h2><ol><li>後端聚合：使用成熟庫（PHP <code>SimplePie</code>, Python <code>feedparser</code>, Java <code>Rome</code>）。</li><li>前端展示：Vue/React 渲染後端 API 返回的 JSON。</li><li>緩存策略：設定合理 TTL（如 10-30 分鐘），避免頻繁請求外部源被封禁。</li><li>內容過濾：剝離 HTML 標籤、腳本，僅保留標題、鏈接、摘要、發布時間。</li></ol><p>純前端方案僅適合靜態頁面演示或受信任的內網環境。</p> <div
