Imacros Regex - Isolate name and surname - regex

Question

I am struggling for quite a while now.
I am extracting text from a Website using Imacros with this result :
Niklaus Hasling
There are whitespaces before the first name and after the surname
This String is stored in the variable !VAR2
I would like to use a regex that isolates the first name in !VAR3 and the surname in !VAR4
Can someone help me ?
I can't figure out how to write the regex
'Extract and Save Names
TAG XPATH="/html/body/main/div[1]/div[1]/div/div[1]/div[1]/div/dl/dt/span" EXTRACT=TXT
SET !EXTRACT EVAL("'{{!EXTRACT}}'.trim(REGEX'')")
SET !VAR3 {{!EXTRACT}}
SET !EXTRACT NULL
'Extract and save SurNames
TAG XPATH="/html/body/main/div[1]/div[1]/div/div[1]/div[1]/div/dl/dt/span" EXTRACT=TXT
SET !EXTRACT EVAL("'{{!EXTRACT}}'.trim(REGEX'')")
SET !VAR4 {{!EXTRACT}}
SET !EXTRACT NULL
enter image description here

Answer 1

I figured this could trim the white spaces before and after the names :
^[ \t]+|[ \t]+$.
and an array could split names, but I cant figure out how with iMacros

Answer 2

Hum, you seem to like XPATH and REGEX, ah-ah...!
Implementation without REGEX (that I don't like and never use):
'Extract and Save First (`!VAR3`) + Last (`!VAR4`) Names:
SET !EXTRACT NULL
TAG XPATH="/html/body/main/div[1]/div[1]/div/div[1]/div[1]/div/dl/dt/span" EXTRACT=TXT
SET !ERRORIGNORE YES
SET !VAR3 EVAL("var s='{{!EXTRACT}}'; var x,y,z; x=s.trim(); y=x.split(' '); z=y[0]; z;")
SET !VAR4 EVAL("var s='{{!EXTRACT}}'; var x,y,z; x=s.trim(); y=x.split(' '); z=y[1]; z;")
'>
'Debug:
SET Debug_Info EXTRACT:<BR>_{{!EXTRACT}}_<BR><BR>
ADD Debug_Info First_Name:<SP>_{{!VAR3}}_<BR>Last_Name:<SP>_{{!VAR4}}_
PROMPT {{Debug_Info}}
!ERRORIGNORE is "needed" in case y[1] does not "exist", or iMacros will throw a Runtime Error...
