Description

seems the command \DTLsubstituteall of the package datatool does remove braces/pairs of matching catcode1/2-character-tokens where you wish to keep them.

The replacement text of a macro definition is formed by the sequence 

  
{InsideBracesA},OutsideBracesA,{InsideBracesB},OutsideBracesB,{InsideBracesC},OutsideBracesC
When using \DTLsubstituteall for replacing each comma by a slash, you don't get 
{InsideBracesA}/OutsideBracesA/{InsideBracesB}/OutsideBracesB/{InsideBracesC}/OutsideBracesC
but you get: 
  
InsideBracesA/OutsideBracesA/InsideBracesB/OutsideBracesB/InsideBracesC/OutsideBracesC
The braces that surround all the phrases "InsideBraces..." get removed.

When replacing commas by slashes with the sequence 

  
{InsideBracesA},OutsideBracesA//{InsideBracesB},OutsideBracesB//{InsideBracesC},OutsideBracesC
you don't get 
  
{InsideBracesA}/OutsideBracesA//{InsideBracesB}/OutsideBracesB//{InsideBracesC}/OutsideBracesC
but you get: 
  
InsideBracesA/OutsideBracesA//{InsideBracesB}/OutsideBracesB//{InsideBracesC}/OutsideBracesC
Only the braces that surround the single phrase "InsideBracesA" get removed.

Seems the behaviour of \DTLsubstituteall regarding the removal of braces cannot be predicted by just reading the datatool-documentation.

\begin{document}
\def\tempa{%
 
{InsideBracesA},OutsideBracesA,{InsideBracesB},OutsideBracesB,{InsideBracesC},OutsideBracesC%
}

All the braces are there there before the replacement:

\texttt{\meaning\tempa}%

\DTLsubstituteall{\tempa}{,}{/}

All the braces are gone after the replacement:

\texttt{\meaning\tempa}%

\null\hrulefill\null

\def\tempa{%
 
{InsideBracesA},OutsideBracesA//{InsideBracesB},OutsideBracesB//{InsideBracesC},OutsideBracesC%
}

All the braces are there there before the replacement:

\texttt{\meaning\tempa}

%Let's replace all commas:

\DTLsubstituteall{\tempa}{,}{/}

Only the first pair of braces is gone after the replacement:

\texttt{\meaning\tempa}

\end{document}
