RE: [xsl] Splitting file into N-sized chunks

["Chris Cosentino (ccosenti)" <ccosenti@xxxxxxxxx>]

Sorry, I don't know a way of doing it in XSL.

In PHP, you can open a file and start writing to it, then periodically
check the size of the file, being sure to close it before you exceed the
300k limit, then continue writing to a new file. You'd have to keep
things well formed of course as well during this process.

See PHP functions: fopen(), fwrite(), filesize(), etc. http://php.net
