Looking for Tips on Formatting Code in Blogger

OK, if you read my last post, you probably noticed that the formatting of the Java and (especially) XML code was, well, not so great. And it took me some time just to get it that good. I have some code-to-highlighted-HTML tools that I like to use, but when I push it into Blogger, it gets mangled in various ways. For all its many faults, Spaces at least didn't give me a lot of trouble in this department. I searched around a bit for techniques and tools to improve this situation. Offhand, I didn't find anything that really impressed me as a good solution. I'll keep looking and trying new things, but in the meantime, if you have some good tips here, please share them.
