>i mean... you used a regex?

That was my initial impression, but after I reread the sentence I interpreted it as he used an RSS parser to get to the element with the data and then used a regex to extract the information from the data.

He didn't specify how the data was formatted inside the RSS element which leaves me to believe it might be something custom and not a simple CSV. This would be a perfectly valid use case for a regex.
