验证RSS提要 [英] Validating an RSS feed

问题描述

我正在开发一个应用程序，该应用程序允许用户将自己的RSS提要添加到各种简单的阅读器中.

I'm working on an application that allows users to add their own RSS feeds to a simple reader of sorts.

当前，我正在使用xml_domit_rss作为解析器，但不确定在解析之前是否确实在验证URL.

Currently, I'm using xml_domit_rss as the parser but I'm unsure if it's actually validating the URL before parsing.

从我可以在线收集的信息来看，好像通过使用服务 https:验证与解析是分开的: //www.feedvalidator.org 或其他一些方法，例如parse_url().

From what I can gather online, it looks as if validating is separate from the parse, either by using a service https://www.feedvalidator.org or some other method such as parse_url().

任何人都对xml_domit_rss的验证方式或将URL发送到解析器之前可以进行验证的方法有什么了解?

Anyone have some insight into either how xml_domit_rss validates, or a method by which I can validate before sending the URL to the parser?

推荐答案

很简单，您可以使用 Atom 1.0 和

It's simple, You can do that using SyndicationFeed. It supports Atom 1.0 and RSS 2.0 versions.

try 
{
    SyndicationFeed fetchedItems = SyndicationFeed.Load(XmlReader.Create(feedUrl));
    // Validation successful.
} 
catch { // Validation failed. };
