The lines 3 to 7 contain the function that we get to write once parseUrl() has retrieved the data and has given us the err and feed results. Line 2 is using the parseURL() function from that library to read our feed. This is what we just imported from the library we downloaded. Line 1 shows us initializing a new RSSParser object.

If your site is a Node project, you can install it using npm by running npm install -save rss-parser, but if you’re just using a basic HTML & Javascript setup, you can download the library by navigating here, right-clicking on the “Raw” button and selecting “Save As…”.įigure 1: retrieving and printing the article titles
RSS-parser is an NPM module which does this perfectly. Fortunately, many libraries already exist which perform this function.

In the new “Blog” section of my portfolio site, I wanted to display the latest three articles from my Medium profile.

This is most likely not the cleanest implementation, just a heads up.I, like many developers, have a portfolio site which doubles up as a kind of CV/Resume.

Print("Errror:fetchxmlasstring ".format(url)) Run Script Running python script for RSS Feed GUI Full Code However when the status code is 2xx no error is thrown after response.raise_for_status call. Unlike JS where any bad response (4xx and 5xx status code) gets thrown as an error, you would have to raise the status to get a similar experience using the requests module. Since we are simply retrieving data, the HTTP verb GET should suffice. Once the url has been validated and cleaned up, we can make requests. Return url Fetch the xml file at the user’s url
This function ensures there are no trailing / characters at the end of the user’s url.
Return scheme in allowedscheme Remove trailing slashes Therefore with the urlparse module, I can extract the protocol or scheme from the user’s input and check if it is either an http or https scheme.
