collapsing unicode white space

[Scott Wilson]

Hi everyone,

I need to implement a W3C processing algorithm which states:

10.1.8 Rule for Getting Text Content with Normalized White Space


        • Let input be the Element to be processed.

        • Return result.







Thanks!

S

The rule for getting text content with normalized white space is given in the following algorithm. The algorithm always returns a string, which MAY be empty. • Let result be the result of applying the rule for getting text content to input. • In result, convert any sequence of one or more Unicode white space characters into a single U+0020 SPACE. The step I'm having problems with is "convert any sequence of one or more Unicode white space characters into a single U+0020 SPACE." The StringUtils replace() and CharSetUtils squeeze() methods would seem to be best suited for solving this one, but there doesn't seem to be a set syntax for easily specifying unicode white space chars defined for one thing. Has anyone else solved a similar problem using commons lang, or should I consider using something else?
