Parsing a String within HTML Options

[SadieJo]

I have need to be able to Parse a string and the available option I have is using HTML - due to the 3rd party application I am using - they allow HTML in their formulas. I need to be able to take a string "[name1, name2, ..., nameN]" and assign each to a variable. There would be at most 8 names within the string, in most cases the number would be 1. Is this possible using HTML? The 3rd party application I am using is Celoxis -- I am creating a custom field within Celoxis, the field I am creating is a "formula" type field - and in the formula you have the option of using HTML. Honestly - I am not sure if this is even possible...
