I have a question regarding an Ajax issue (not using jQuery)... I am trying to extract the URL from a blog that has an RSS feed in XML format. I am attempting to access the link using Ajax, which is working fine most of the time. However, sometimes I encounter an error when I try to access the same link but with a different blog name that redirects to FeedBurner instead of the original blog.
Here is a screenshot of the code: https://i.sstatic.net/qp3gT.png
