Is there a way to change names of various attributes at the same time?

cdaponte

I have created 20 attributes, and after that i realize that i want to have all the names of the attributes in uppercase, but if i change the name directly from Generate attribute operator i have to change all the functions that are correlated with attributes.

Then you can use "rename operator" and enter the name and new name. You can give as many attributes as possible by selecting "rename additional" option.

If you would like to set an attribute name something like "att_1" "att_2... in a sequence, you could also use Rename by generic name operator.

Hello @cdaponte

You can use "rename operator" or "rename by replacing operator" based on your attribute names.

Hope this helps. Please inform if you need more information.

I have tried with the rename by replacing operator but i don´t have the results i want because each operator has a different name, so what i want to replace is different in each one.

Hi,

i think the only way to do this is to take the XML and do Search and Replace in a text editor as of now.

I know that this is an older thread, and there is already an accepted answer, however, I had this issue and the above solution didn't work for me since my variable names were always changed.  I created a loop attributes with a rename and a macro variable inside.  Here is the xml using the titanic dataset.  Hope this helps someone.
