Re: Assistance with "Replace String Using Regexp"

Ugh

Perhaps it would be better use String library Get Substring [1] and BuiltIn library Catenate keywords.

Split the string from correct point in two portions. Then use the Catenate to add the comma as correct separator.

Hello,

 

I would like to replace 12345 with 12,345. I am running into issue with the replace portion of the regex.

 

${MYTest}=     Replace String Using Regexp      ${MYTest}      (\\d{3}(?!$)))     $1,

Could someone point me in the correct direction here? Or is there a better way to add commas to numbers?

 

Thanks.

Dennis,

You were on the right track but your regex was a little messy. Also, you don't refer to matched groups with $n, but rather \\n.  I was able to get what you needed with the following:

${test}= Replace String Using Regexp 654321 (\\d{3}$) ,\\1

Running this and logging the output:

[ WARN ] 654,321

This regex only works, however, for numbers less than 999999.  If you wanted to match those, you'll have to construct a more complicated regex that will match middle three numbers.  Or, you can use Split String keywords in conjunction with this to do what you need.

Hope this helps,

Roj
