Hi there,

I started using Rapidminer 5 recently, and I want to Cluster the content of around 100 Blogs.

I set up the tool to cluster the content of one homepage. I generate the data with the function Read RSS Feed. My question is if there is a possibility to use an excel list with the url's of all the blog i want to store the data instead of typing every single url in the function Read RSS Feed.

Thanks a lot for your help,

    Try using macros, e.g.:

    <process version="5.3.008">

        <input/>
        <output/>
