need convert the code having nested If conditions to Foreach()

Question

Hi Team, 
 
 Could you please help me in converting the following code into Foreach() 
 if(
 isnull(
 local!region
 ),
 if(
 rule!APN_isEmpty(
 tostring(
 index(
 local!userlist.data,
 "regionId",
 {}
 )
 )
 ),
 if(
 rule!APN_isEmpty(
 tostring(
 index(
 local!userlist.data,
 "lobId",
 {}
 )
 )
 ),
 if(
 rule!APN_isEmpty(
 tostring(
 index(
 local!userreg.data,
 "regionId",
 {}
 )
 )
 ),
 {},
 local!distuserregname
 ),
 null
 ),
 tostring(
 rule!CTR_QE_getRegionNameByRegionId(
 index(
 local!userlist.data,
 "regionId",
 {}
 )
 )
 )
 ),
 local!region
 ) 
 
 Thanks in advance.

My issue got resolved with the following query. 
 
 a!forEach(
 items: local!userlist.data,
 expression: if(
 isnull(
 local!region
 ),
 if(
 rule!APN_isEmpty(
 tostring(
 index(
 fv!item,
 "regionId",
 {}
 )
 )
 ),
 if(
 rule!APN_isEmpty(
 tostring(
 index(
 fv!item,
 "lobId",
 {}
 )
 )
 ),
 if(
 rule!APN_isEmpty(
 tostring(
 index(
 local!userreg.data,
 "regionId",
 {}
 )
 )
 ),
 {},
 local!distuserregname
 ),
 null
 ),
 tostring(
 rule!CTR_QE_getRegionNameByRegionId(
 index(
 fv!item,
 "regionId",
 {}
 )
 )
 )
 ),
 local!region
 ),
 )
