CSS child combinator with one-letter selectors Java regular expression pattern matching

My goal is to switch from using the CSS child combinator ">" to the XPath child combinator "/".

After considering various existing CSS selectors and removing some white spaces, I attempt to match the following regular expression:

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

and replace it with:

$1/$2

This method has been successful in most cases, except for situations where a selector consists of only one character positioned between two child combinators, like "div>a>div".

Does anyone have suggestions on how to correctly handle single-letter characters?

Here are some examples:

Thank you!

Answer №1

I have to reiterate Alex's query. Why not simply substitute > with /?

But, if you are determined to verify that the > has content on both sides, then lookarounds are the ideal solution.

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

This only captures the >, so replace it with /.
