Multi-value Field extraction

Hello,

I would like to create a multi-value field for my data, how can i do that?

here's a sample of my data (Starts at QAM)

event1 = QAM 32209 Prog 238 Path PATH_MW

event2 = QAM 23001 Prog 25 Path PATH_MG PATH_VERTE

event3 = QAM 46201 Prog 180 Path PATH_MD_1 PATH_JAUNE

The field i am trying to extract is Path but as you can see in the sample above, path can have a single value in the case of event1(PATH_MW) or multiple values in the case of event2 (PATH _MG PATH _VERTE) and event3 (PATH _MD _1 PATH _JAUNE)

This regular expression finds them but considers multiple values as one (?i) Path (?P<fieldname>[a-z_]+.[a-z_])

Here the values for event 2 and 3 are considered as one even if we have two values, what can i do so that it stores the two values in the path field for the same event but see them as two different values.

Thank you in advance.
