Hi all,

I have no idea.

I have many event like this.

/abc_d/efg_h/abcd_ef/1234/ghi_jk/
/abc_d/efg_h/zxcv_vf/56789/sdfg_h/
abc_d/egf_h/dfghh_h/5y865/ghjk_r/

/abc_d/efg_h/ is common.

so, I want to do regular expression by specifying the beggining.

I think it is working.

|rex field=_raw"(?<unitpath>[/abc_d/efg_h]/\w+_\w+/\w+/\w+_\w+)"

but Error happen.
I know I am wrong, but I have no idea.
I wish this was recognized as a field by default..........(;;)

Could you help me?

Thank you.

Hi nanachu,

If I understand it correct you can try this regex:

| rex "[\/]*abc_d\/[efg]+_h(?<unitpath>\/\w+_\w+\/\w+\/\w+_\w+)" 

That will match

/abcd_ef/1234/ghi_jk/
/zxcv_vf/56789/sdfg_h/
/dfghh_h/5y865/ghjk_r/

Hope this helps ...

cheers, MuS

check if this what you are looking for.

I am extracting the individual fields after the common information(/abc_d/efg_h/)

| rex field=raw"\/abc_d\/efg_h\/(?P\w[a-zA-Z].)\/(?P\d.)\/(?P\w[a-zA-Z_]*)"

Thank you for hepling me.
I thought only rex field = could be used.
I have to read documentation carefully again.
I learned a lot.

Thank you so much.
