i have a variable that contains the string: attribute_value[XXX][] where XXX every time that page loads is a 3-digit number that changes every time.
How can i use .replace function in javascript to replace attribute_value[XXX][] with something specific regardless the XXX value?
Thank you in advance
You can use regular expression for that
str.replace(/attribute_value\d+/, 'aa');
here '\d' indicates digits and '+' indicates one or more occurances
str.replace(/attribute_value\d{3}/, 'aa');
Use this if you want to replace only first 3 digits

I have written a regular expression which matches all header HTML elements, including their text. The present regular expression I am using is: /<(h[1-6])[^>]*>(.*?)<\/\1>/gi.
I want to match all headings and text until testing-options appears in the string below:
<h1>jfhfnjkgf</h1><h2>fegsg</h2><h2>fwegrweghrw</h2><h4>sfadfsaf</h4><h4>ukfdsnsjkfsd</h4><ac:structured-macro ac:name="testing-options" ac:schema-version="1" data-layout="default" ac:local-id="8bbfe293-eeb9-4785-9873-9fb9b218692b" ac:macro-id="bed737bbfaaf5f1df5f68a0ecc0bc6a7"><ac:parameter ac:name="enable-testing">disable</ac:parameter></ac:structured-macro><h3>bkbkvwv</h3><h4>vbdkhvbkwv</h4><h3>v n vw bv</h3><p />
The final regex provided should match every heading and text until testing options appears in the string above. In this case, the match should be: <h1>jfhfnjkgf</h1><h2>fegsg</h2><h2>fwegrweghrw</h2><h4>sfadfsaf</h4><h4>ukfdsnsjkfsd</h4>.
Use the following Regex without global flag
(<h[1-6]>\w+<\/h[1-6]>)*

I have an array of strings denoting variants of shirts in my store.
Here is an example string:
Apparel-DTG-Tshirt-District-DT6000-M-Black-Mens-CF-20200304113232677
All of the strings share same structure and the rule that I need to implement is, extract what's in between 5th and 6th occurrence of - (dash). In this particular case this is M.
How do I do that?
This would help you. The first capturing group will be the value between fifth and sixth dash:
https://regex101.com/r/UlQBqy/2
const re = /^(?:[^-]*-){5}(.*?)(?=-)/
console.log("Apparel-DTG-Tshirt-District-DT6000-M-Black-Mens-CF-20200304113232677".match(re)[1])

I have a requirement to allow any digits with only one character (either w or d or W or D) at a time with no sequence.
For example: 2 or 2w or 222W or 2d or 222D
(not like 2wd, 55dw, 2w5d, 2w5w, 2D5D etc)
Could you please provide solution on this. Thanks.
Try the following:
^\d+[wdWD]?$
Try it out:https://regex101.com/r/sYqjTi/1
If you don't want it to match just 2, remove the ?, it will make the last letter required.
This regex should work both on Java and JavaScript.

I have a problem in some substitution in javascript (HTML).
I need to substitute ONLY the tags around every number, e.g.
<1>
become:
<sub>1</sub>
or
<20>
become
<sub>20</sub>
etc.
How can I do?
Thank you so much!
You can use replace and regex with groups to achieve this:
var text = '<1>blabla<20>';
var newText = text.replace(/<(\d+)>/g, '<sub>$1</sub>');
console.log(newText);

I need to replace all word in except one word. the first word that contains "Thewo"
How can i do this with a RegEx?
Input String "We need to remove something from and keep a word Theword and save only first word Thewood Theworld"
Expted exsult: Theword
This will do what you want:
input.match(/\w*Thewo\w*/)
Since you are asking for the first word that contains "Thewo", I assume that "Thewo" can appear in the middle of a word. For example, it will match notTheworker in "and notTheworker here".
