Hi forum,

How can I put the output of a PHP script and cache it in a static XML document? I presume I will have to use output buffering and write it to the file somehoow?

Exactly!

Send an ob_start() at the beginning of your script, and use an ob_get_clean() to retrieve the text in a variable.

Then, it's up to you to write it in a file, or store it in a db.
If the process needs to be site-wide, take a look at the auto_prepend_file and auto_append_file php.ini directive (you can set them up on a per-host base too, via .htaccess).
When I needed this, I did the ob_start in the prepended file, and the get_clean + storage in the append.

That way, I did not need to modify the already used scripts.

How would I go about specifying paths and file names for the outputted files?

Let us say I generate a lot of documents via something like WordPress. How could I get static versions of all the dynamically created pages?
