## About
RSS and Atom deserialization module for Deno.
The project aims to provide a
lightweight and easy-to-use feed deserializer.
[Check out the deserializer in this online
showcase](https://repl.it/@MikaelPorttila/Deno-RSS-Module)
## Usage - Download and parse feed
### Download and parse feed
```typescript
import { parseFeed } from "jsr:@mikaelporttila/rss@*";
// Or by using Denoland direct import
// import { parseFeed } from "https://deno.land/x/rss/mod.ts";
const response = await fetch(
"http://static.userland.com/gems/backend/rssTwoExample2.xml",
);
const xml = await response.text();
const feed = await parseFeed(xml);
// Your code...
```
### How to access Dublin Core or MediaRss fields (RSS and RSS2 Only)
```typescript
import {
DublinCore,
MediaRss,
parseFeed,
} from "https://deno.land/x/rss/mod.ts";
const response = await fetch(
"http://static.userland.com/gems/backend/rssTwoExample2.xml",
);
const xml = await response.text();
// Optional destructuring assignment
const { entries } = await parseFeed(xml);
// Access fields using the DublinCore and MediaRss enums
const dcTitle = entries[0][DublinCore.Title];
const mediaContent = entries[0][MediaRss.Content];
```
