Java regular expression matching for CSS child combinator with one character selectors

I would like to replace the CSS child combinator ">" for the XPath child combinator "/".

Considering different existing CSS selectors, and after scaping some white spaces I try to match the regular expression:

([\w\-\*\.\#]|[\[[^\]]+\]])>([\w\-\*\.\#]|\[ )

and replace it with:

$1/$2

This works fine for all the cases I've found but one: when one of the selectors has only one character, and is caught between two child combinators, such as: "div>a>div".

Does anybody know how to handle the one letter character correctly?

I leave here some examples: http://fiddle.re/4xkrt

Thanks!

I must repeat Alex's question. "Why don't you just replace > with /"?

However if you insist to check that the > has content on both sides then lookarounds are the way to go.

(?<=[\w\-\*\.\#]|[\[[^\]]+\]])>(?=[\w\-\*\.\#]|\[ )

This just catches the > so replace with /.
