Subsequent to Why this regex does split second double quote but not first double quote?

I now added :, problem is I don't want to split if it is inside double quotes:

I included a lot of background information to help you answer this question, however you can skip down to the heading called 'Questions' to skip to the main point.

I'm new to using Cordova, and I'm new to an existing Cordova project I want to further develop. As a result, when I look at the project files, I am not sure what are choices made by the previous developers and what are choices made automatically by Cordova. I suspect that Cordova generates a lot of files that are not created by the application developers because in my case there are over 7900 files including source code and README's, and the application was previously (to my knowledge at least) developed by only one person.

While many questions could be asked from that perspective, I would like to narrow in on a specific question to avoid being too broad. I've noted that are many files within the path structure called index.js.

I've tried several patterns and fiddling with some pattern from Capture word between optional hyphens regex, Regular Expressions: How to find dashes between words, What's the difference between "(\w){3}" and "(\w{3})" in regex? and also read Reference - What does this regex mean?

My best attempt so far was: (\w{3}\-)

with test data:

THU-abs-sss-ddd

012-aa-aaa-aaa

which match:

Despite what I would like to achieve is an exact pattern validation against: XXX-XXX-XXX-XXX where XXX is 3 alphanumeric and dash repeated 3 times and closed with another XXX alphanumeric.

I've also tried using (\w{3}\-)(\w{3}) but then the result was:

What am I missing to complete the pattern?

Context is SQL on the AS/400 (IBM i)

My goal is to end up with two values: a string determined by a regex I already have, and then everything else in the source string with the result of the regex removed and the gap (if any) closed up.

Here's the SQL:

So, for example, I have this list:

I am trying to init a new react native project via the React Native CLI. I am on the most recent version (2.0.1)

Then, I run the standard React Native Init command and the new project builds with all of these unmet peer dependency warnings:

I'm struggling to match and keep all CSS rules containing the string 224,13,78.

Sample input:

I always use to develop my projects natively for Android and iOS, but after many people talking to me about react-native, I decided to give it a try.

However, I got very frustrated at the very first initial step: create my first project.

This is my environment:

• macOS Mojave 10.14
• Xcode 10.0
• node v10.12.0
• watchman 4.9.0
• react-native-cli: 2.0.1

When I run the command react-native init AwesomeProject, I see many warnings like this:

There are a plethora of questions about lookbehinds in VBA. The problem is that, while there are positive and negative lookaheads, VBA doesn't support lookbehinds at all.

Most of the questions people have asked seek to solve a very specific problem of extracting strings from text and the Stack Overflow community has been very helpful in providing workarounds for these particular cases. My question is, could you write a function in VB that simulates positive lookbehind by accepting Regex patterns as arguments and doing some kind of find-replace in the resulting string to only return the desired match group while omitting a (required but not captured) prefix?
