I need to cross-reference the item in enumerate. Here is what I have.

documentclass[12pt]article
begindocument

beginenumerate
 item Solve $x^2=1$.
 item Solve $x^2=4$.
 beginenumerate
 item labelenum:1 Find all roots.
 item For each root in (refenum:1), subtract 2 from it.
 endenumerate
endenumerate

enddocument

It works fine but I want to have (a) instead of (2a) in the last line. In other words, I only want to have the label within the current enumerate. Thanks.

The key is to redefine the macro p@enumii, which holds the prefix used in this situation:

documentclass[12pt]article
begindocument

beginenumerate
 item Solve $x^2=1$.
 item Solve $x^2=4$.
 beginenumerate
 makeatletter
 renewcommand*p@enumii
 makeatother
 item labelenum:1 Find all roots.
 item For each root in (refenum:1), subtract 2 from it.
 endenumerate
 item To show that the redefinition is local:
 beginenumerate
 item labelenum:2 Find all roots.
 item For each root in (refenum:2), subtract 2 from it.
 endenumerate
endenumerate

enddocument
