extracting name from retrieved dataset as subdirectory name

mansour_ebrahim

Dear All
Somehow I need a tool to extract a name from the Retrieved dataset (its name) and set it as the name for new subdirectory when I use Create Directory operator.

Hello @mansour_ebrahim

You may want to see the Annotate, the Extract Macro from Annotation operators.

I just made a few tests, nothing important but see this process:

Hope this helps,

Many thanks. Sorry but I don't know how to use xml? Is there any operator to use? Or can you tell me how to use these codes?

Hello @mansour_ebrahim

To use the XML, you need to open a new process in rapidminer. After that, you need to go to View --> Show Panel --> XML present in the menu bar of rapdiminer. You need to copy the XML code provided in the above post and paste it in the XML window of rapidminer, then click the green tick mark on the XML window and you can see the process mention by rodrigo in your RM.

Thanks,
Varun
