Question

I try to be able to extract the html element name that comes in 2 form in one regexp in perl
for example i have this :

document.all.ElemName.

and also

document.all[“ElemName“].

and this

document.all[‘ElemName‘].

and i need to get the ElemName ,
i can only capture one opetion , is it posible to extract it in 1 regexp ?
this is what i have :

document.all[\.\w|\[](\w+) 

that capture only the first example

Answer 1

This will match all three cases with ElemName in the first capture group:

document\.all\.?(?:\[["'])?(\w+)(?:['"]\])?
