No.

No XML. No colons. No newlines. No embedded whitespace.
No quoting. No field names. No other screwing around.

Option 1 looks like this: 42 8842 0 4234 898 33 221 2512

Option 2 is a raw array of 64-bit binary data

Anything else, and somebody like you will be tempted to muck with it.
We've seen spelling changes and column alignment break things. We've
seen parsers break on /proc/cpuinfo because someone decided whitespace
and extra columns might be nice. XML wouldn't be immune to the recent
"features" vs. "flags" problem, but the two options above are.

Now, what is your problem? Grab libgtop (GPL) or libproc (LGPL) and
be happy. All of "ps" is in fact under the LGPL, so you can grab
anything else you might need. (LGPL: not just for libraries anymore)

You get libproc and ps here: http://www.cs.uml.edu/~acahalan/procps/
(maybe wait a week or two before you grab that -- new one coming)
