Hello ,
i would like to use Regex to find three cases :
1.the string that starts with one letter then numbers as example a73939 or s939
2.and also to find string like S2820_hjd
(one letter then few numbers then underscore then numbers or letters )
3.and any string that start with one letter then underscore as O_Sjdld
i tried using string searcher transformer but I am not sure which regex should I type ?

So a string starting with a letter followed by one or more numbers
^[a-zA-Z][0-9].*^ start of line
[a-zA-Z] matches a single character
[0-9] matches a single number
.* matches any character an unlimited number of times
A string that starts with one letter then an underscore
^[a-zA-Z]_.*^ start of line
[a-zA-Z] matches a single character
_ matches an underscore
.* matches any character an unlimited number of times
You can put them together separated by a pipe in the StringSearcher so anything that matches one or the other will exit the Matched port
e.g.
^[a-zA-Z][0-9]{2}.*|^[a-zA-Z]_.*
