ReplaceText processor - $ symbol escaping done incorrectly

[Asanka Sanjaya Herath <an...@gmail.com>]

Hi,

I'm using Replace text processor[1] to build a json in my flow file.

Flow file has following attribute:


*messageId: 001201d20dd3$7bcdc870$73695950$@xx.yy.co <http://xx.yy.co>*

Replace text processor "Replacement Value":

*{*
*"messageId" : "${messageId}"*
*}*

And all other properties are set to default values.

So that I'm expecting the flow file content output to be this:

*{*
*"messageId" : "001201d20dd3$7bcdc870$73695950$@xx.yy.co <http://xx.yy.co>"*
*}*

​But it actually is:
*{*
* "messageId" : "001201d20dd3\$7bcdc870\$73695950\$@integramicro.co.in
<http://integramicro.co.in>"*
*}*
​
All $ characters are combined with a \ character. Can someone help me to
get rid of these slashes? Any help would be highly appreciated.

@james, Yes that was the problem. I changed "Regex Replace" to "Always
Replace" and it worked fine. Thanks so much for the help.

Re: ReplaceText processor - $ symbol escaping done incorrectly

In your ReplaceText processor, is the Replacement Strategy property set to
the default "Regex Replace"?  You might try "Always Replace" or changing
the Search Value to ".*" (without quotes).  I suspect it is escaping your $
as part of processing the regex.


Thanks,

James
