Hi,

All I want to do is replace multiple character in a field's value.

The text in the field is:

'I have different characters'

If I try ${field.value:replace('a', 'i')} it works. The output is 'I hive different chiricters'

Bu I want to replace one more character. How can I do this in same processor.

I have tried someting like ${field.value:raplace('a', 'i'); field.value:replace('e', 'u')}

I couln't find the right syntax. Please help.

Hi ,

I think the right syntax will be :

${field.value:raplace('a', 'i'):replace('e', 'u'):replace(...)}

Hope that helps.

Thanks

Thank you Samsal. I have tried different combinations but I am suprised I did not try this one. This is javascript syntax, right? If I learn beginner level javascript, is it going to be easier to use NiFi's expression language?

Hi,

You dont need to have programming language to learn Expression Language. It can help but its not required.
