I have a string where I need partial data that is located various (start) indexes using regex.
Input String
Hello, This community is here to help you with specific coding, algorithm, or language problems.
Expected Result
community is with specific language problems
I have individual regex patterns to grab the info I need. But I don't know how to combine together so that I can achieve my expected result. I could use a loop and then append the previous results through my code. Before that I wanted to see is there a solution so that I can avoid loop.
(?<=This).*(?=here)
(?<=you).*(?=coding)
(?<= or).*
You may use
/.*?\bThis\b\s*(.*)\bhere\b.*?\byou\b\s*(.*?)\bcoding\b.*?\bor\b\s*(.*)/
See the regex demo.
Details
.*? - any 0+ chars other than line break chars, as few as possible\bThis\b - a whole word This\s* - 0 or more whitespaces(.*?) - Group 1: any 0+ chars other than line break chars, as few as possible\bhere\b - whole word here.*? - any 0+ chars other than line break chars, as few as possible\byou\b - whole word you\s* - 0 or more whitespaces(.*?) - Group 2: any 0+ chars other than line break chars, as few as possible\bcoding\b - whole word coding.*? - any 0+ chars other than line break chars, as few as possible\bor\b - whole word or\s* - 0 or more whitespaces(.*) - Group 3: any 0+ chars other than line break chars, as many as possibleSee JavaScript demo:
const regex = /.*?\bThis\b\s*(.*?)\bhere\b.*?\byou\b\s*(.*?)\bcoding\b.*?\bor\b\s*(.*)/;
const str = "Hello, This community is here to help you with specific coding, algorithm, or language problems.";
console.log(str.replace(regex, "$1$2$3"));
