Talend - Exclude files withe a specific mask

Question

I recover from a FTP server, flat files which has these names:

• abc
• abc.flag
• abc.tmp
• test
• test.flag
• test.tmp

In my case, I have to recover just the files: abc and test. I tried with the following mask but it did not work: "(.+\.tmp)| (. + \.flag) " is there another way to do this ?

Answer 1

Can't find of an expression that would select all but .tmp and .flag files, but here's an example to select them, which uses .+(?:flag|tmp)$.

Updated

Assuming negative lookaheads are allowed, see this example that only selects non .tmp and .flag files, which uses

^.+\.(?!flag|tmp).+$|^\w+$
