Aw: ReplaceTextWithMapping how to regex

[Uwe Geercken]

Hi,

 

you might want to use the ExecuteRuleEngine processor I wrote. It allows you to do very complex checks on the data and then also update it.

 

In other scenarios the MergeTemplate processor might work as well.

 

have a look at: https://github.com/uwegeercken/nifi_processors

 

rgds,

 

Uwe

Betreff: ReplaceTextWithMapping how to regex

Hi all

I'm not sure I understand how the ReplaceTextWithMapping processor
works. Let's say my flowfile content looks like:

xyz key=value1 foo bar value1

My mapping file looks like:

value1 replacementvalue1

value2 replacementvalue2

I just want to replace the occurrence of "value1" only when it's
perpended with "key=". Therefore I'm writing the Regex "key=(\S+)" and a
"Matching Group" of 1.

This unfortunately doesn't work.

Can someone explain, what's wrong?

Thanks!

Mika>
