If one of your (presumed) tabs in the original data is actually a space, your regex will fail. Likewise, if the offending element is two tabs... KA-BOOM! So, as advised in the consideration, you should add code tags around your sample data (for our ease of helping) and use any one of a host of tools to doublecheck the separators.
