I'm torn. The article is well written and the code examples are pertinent to the article. However...

It was a quick read I did through the article so I may have missed something, but I didn't see anywhere where non-validated "elements" in the input string were handled. I saw where an "alert" was created if there were no matches, but didn't see anywhere individual elements would produce an alert if the existed.

For all of you good folks using XML to split things... I suppose that XML either does something special for you or that your consider its performance to be good enough. Just be aware that there are faster methods than XML... sometimes a lot faster.

Last but not least, this reminds me of the old "LIKE" method which also failed to notify if a single element of a parameter could not be validated with the only difference being that the validation list is table driven instead of built into code.

I'll try to post some test code tonight to show all of what I believe can happen with the code from the article. I might even have time to show why I don't use XML splitter code.
