Re: Refactoring parsing code with XSLT 2.0

Micah,

Do you want to potentially keep track of what goes with what... in
other words do you want to walk away with a set of elements that have
the value, unit short name, and unit long name for example...

Actually, no matter what your desired output is in 2.0 this type of
functionality is serviced via the tokenize() function whose sole
purpose is to seek out a regex pattern to then split the string into
substrings... obviously in this case you are only looking for one
instance but no matter one or n^x the result will be a sequence of
substrings that have been split based on your regular expression.

The format for the tokenize() function is tokenize(string, regex,
optional regex flag) where the data types are xs:string?, xs:string,
and xs:string respectively.  As mentioned the result is a sequence
whose data type is represented as xs:string*

Of course now that you have a sequence you can treat it just like any
other sequence and process it further or output it accordingly as you
continue through the processing of your stylesheet... sequences, of
course, are one of the nifty built-in features courtesy of XPath 2.0,
the choice of a new X-enabled generation ;)

Cheers :)
