Hello everyone,
I would like to ask for help on how to use Regex correctly. I am trying to extract access token on a txt file.
This is what I am trying to extract
I am using this syntax “System.Text.RegularExpressions.Regex.Match(result.TextContent, “(?<=access_token[””:\s]*)[A-Za-z0-9-_]+“).Value” but its only extracting the first 4 digits (1000).
any advice on what the correct syntax is?
Hello @mapaje Try this regex
System.Text.RegularExpressions.Regex.Match(result.TextContent, “(?<=access_token"\s*:\s*“)[^”]+”).Value
Cheers
Hi, @mapaje
use the following regex pattern:
System.Text.RegularExpressions.Regex.Match(
result.TextContent,
““access_token”\s*:\s*”([^“]+)”"
).Groups[1].Value
@bhavesh.choubey and @arjun.shiroya,
Thank you for the help, I have tried both and they have given me what I wanted to extract.
Hey @mapaje you’ve to mark the correct answer as solution not yourself as a solution. If you want to be marked as solution then give the answers to the topics not just raise the topic and mark yourself as solution.
Cheers
Thank you for the advise, I will be doing that then.
Hi
Your original regex pattern looks to be failing because you didn’t consider the “.” values in the token.
You just needed to update the square brackets with a “\.” The backslash is to escape the “.” in regex. You need to escape that character within the square brackets because “.” means any character.
Cheers
Hello @Steven_McKeering
Thank you for this, I am new to coding so this is very helpful as I am currently learning syntaxes.
