How can I convert a bunch of .xml files to an eBook format with nice formatting?

[wellsterhubble]

I have a folder filled with 4chan threads, each thread can contain any number of comments. I want to create readable files for my Kindle, with multiple threads per book, with each thread clearly defined for the person reading it, each comment showing details that are present in the .xml file, such as 'date of post', the post number, the comment text, etc.

I want to be able to combine multiple threads from a single folder, so I can decide what threads I’d like to combine into a single ebook file.

My understanding is that the best way to do this would probably be to somehow represent the .xml data in an .html file which I can easily convert to .epub or .mobi format. My problem is I don’t know how to convert the .xml data into something readable and tidy in an .html file…and I don’t know how I’d do this en masse for many .xml files at once, combining some of them.

Two .xml files on the left, and the outcome that I want on the right.

showing basically the outcome I want, the formatting doesn’t have to be exact, I just want it tidy and readable, in a format that I can change the font size, etc on my Kindle as you would with any other ebook file.

It depends on what is in the XML files, XML is just a container format. Typically you would use xslt styesheets and something like xslt-transform to do this.
