Text Formatting ⇒ xstring \StrBetween not working with \ref

[jep]

Hi,

Could someone explain to me why this isn't working?

Code: Select all

\documentclass{article}

\usepackage{xstring}
\usepackage{enumitem}

\begin{document}

\begin{enumerate}[label=(\arabic*), labelindent=\parindent, leftmargin=*, rightmargin=.5in] 
	\item This is a test premise. \label{Premise-1}
\end{enumerate}

This is the context of the ref to Premise-1: \ref{Premise-1}

% This does not work. The output in \outputtestA is blank.
Test A:
\def \testA{\ref{Premise-1}}
\StrBetween{\testA}{(}{)}[\outputtestA]
\outputtestA

% This works fine.
Test B:
\def \testB{(1)}
\StrBetween{\testB}{(}{)}[\outputtestB]
\outputtestB

\end{document}

It seems to me that Test A should work just like Test B does. If that's not the case... what am I missing and how do I fix it?

Thanks!

Here's a clarification of what I'm trying to do here. The \ref points to an enumeration - for example (1). I want to strip the parentheses so that I end up with just 1.

Any help is REALLY appreciated.

Why don't you just use enumitem's ref= option?

Code: Select all

\documentclass{article}

\usepackage{enumitem}

\begin{document}

\begin{enumerate}[label=(\arabic*), labelindent=\parindent, leftmargin=*, rightmargin=.5in, ref=\arabic*]
   \item This is a test premise. \label{Premise-1}
\end{enumerate}

This does not have parentheses: Premise \ref{Premise-1}

\end{document}

That will work! Thanks!
