Choose \documentclass dependent on compiler

Question

I am not able to compile this tex document

\documentclass{scrartcl}
% \documentclass{article}
\begin{document}
hello    
\end{document}

with htlatex. I am able to do this using pdflatex. If I choose article (see 2nd line) as documentclass, everything is fine. However, I'd like to have pdfs using scrartcl. How can I switch between documentclasses dependent on the compiler I use?

Answer 1

\RequirePackage{ifpdf}
\documentclass{\ifpdf scrartcl\else article\fi}

\begin{document}
hello    
\end{document}

Or, may be (I don't know) it's better not to risk anything

\RequirePackage{ifpdf}
\ifpdf
  \documentclass{scrartcl}
\else
  \documentclass{article}
\fi

\begin{document}
hello    
\end{document}
