Regular expression and wildcards

File Name Recognition Feature 

  • You may specify the filename that will phrase the naming convention. 
  • You may want to define the different tasks for the same subfolder.
  • In some situations, files use a naming convention that has to be filtered to select a very specific type of names
  • Using wildcards and regular expressions it is possible to create a formula for advanced data filtering
     

Wildcard example:

One subfolder can store measurements from different presses and different print conditions (substrates):

LS0000795-coated_135-333278-IC1-2019_07_12-Sheet7-Prinect_Fogra4-1.txt

LS0025448-uncoated_90-333278-IC1-2019_07_12-Sheet7-Prinect_Fogra4-1.txt

T007-pvc-01-IC2-2019_08_13t11_46_43-sheet1-sheet1-tvi_l_colorcal35-4.txt

 

In this case, we can find the following strings:


-IC1- data from press_01
-IC2- data from press_02 
-coated_135-  substrate/print condition A
-uncoated_90- substrate/print condition B
-pvc-  substrate/print condition C 

 
a. To select all jobs from Press 01 printed on Coated paper  enter: 

*-coated_135-*-IC1-*.txt

b. To select all jobs from Press 01 printed on Uncoated paper enter: 

*-uncoated_90-*-IC1-*.txt

c. To select all jobs from Press 02 printed on PVC  enter: 

*-pvc-*-IC2-*.txt

In this example, we have a wildcard selection "*" - means any value in the string. This is the simplest way to filter files by decoding the filename.
