Hi,

I am trying to remove all new lines from base64encoded string using replaceText processor.

Properties for replaceText processor is as follows:

Search Value : \\n

Replacement Value:$1

Character Set: UTF-8

Maximum Buffer Size: 10MB

Replacement Strategy: Regex Replace

Evaluation Mode: Line-by-Line

But this not working.

@Biswa

Your "Replacement Value" is set to "$1".

This means that the replacement value is the value associated to the first java regex capture group found in your configured "Search Value".

The issue is your "Search value" contains no capture groups.

Perhaps providing a sample input content and desired output content would help here.

Hope this helps you,

Matt

@MattWho It is not newline, its CTRL M (^M) characters. I am able to see the ^M characters in vi editor.

May be it will be useful for someone.

I used searchValue as "\p{C}" and ReplaceValue as empty String

\p{C} finds all non-printable characters.
