I’m a huge fan of low-tech approaches to a lot of my TBX problems. For example, if you have the URLs in the text of notes and simply select all the notes: the list you are looking for will appear in the note pane. Your can cut-and-paste it from there for print in a text file. If the order of the list isn’t what you want, you can rearrange it in outline view. (The list in the note view is stacked in the note’s outline order).
I use this technique all the time to prepare docs for my own students.
Finally, if you want specifically to export and haven’t looked at them yet, maybe these posts about basic custom export from Tinderbox might help.
