Graphics, Figures & Tables ⇒ vertical curved arrows between rows

[Sagil]

I wanted to typeset an array with curved arrows leading from one line to the next, as shown below (well, I tried):

/ Line 1
(
\ > Line 2
(
\ > Line 3

Is there any easy way to do this? I know xy-pic can do curved arrows, but always seems to introduce huge spacing between lines..

Try one of the more advanced vector graphics packages like PSTricks or TikZ.

Thanks, I've had a look at pstricks, and found that pst-node.sty should make it possible. Unfortunately, I can't even get the most simple examples to run - lines are simply not drawn. E.g. for the document below, I only get
text1 [blank space] text2
without any connection in between, when it should be
text1 ------------- text2
Any ideas what could be wrong?

\documentclass{article}
\usepackage{pst-node}
\begin{document}
\rnode{A}{text1} \hspace{2cm} \rnode{B}{text2}
\ncline{A}{B}
\end{document}

Edit: Nevermind, it works when you compile dvi->ps->pdf instead of directly dvi->pdf
