How can I tweak this camelCase regex to allow for acronyms?

edit: strictly speaking, they are not acronyms but you get what I mean.

I have found this resource very helpful, https://newbedev.com/regex-for-pascalcased-words-aka-camelcased-with-leading-uppercase-letter but what if I need to tweak the lower camel case version to allow a set of initials to be used in the middle of a name. For example, the author provides a regex for lower camel case, [a-z]+((\d)|([A-Z0-9][a-z0-9]+))*([A-Z])?, which would match the following words:

xmlHttpRequest
newCustomerId
innerStopwatch
supportsIpv6OnIos
youTubeImporter
youtubeImporter
affine3D

but what about;

xmlHTTPRequest

where the capialized string features in the middle of the name?

If i understood you correct you just have to add a + after [A-Z0-9] like this:

[a-z]+((\d)|([A-Z0-9]+[a-z0-9]+))*([A-Z])?

I would use this version, which allows for multiple capital letters:

[a-z0-9]+(?:[A-Z0-9]+[a-z0-9]*)*

Here is a demo showing that the pattern is working for you new edge case.
