[magnolia-user] removing character in last iteration output

[dawnJ2SB]

I am creating a footer link paragraph editor which allows me to dynamically
add as many links in the footer as needed. However, between each link is a
" | " character. This character should only be visible BETWEEN the
links, not before the first or after the last. I tried using your
ifLastContentNode function, but haven't found the right formula to make it
work. %-|

Do you know how to make it work? Or know of another way?

<cms:ifNotEmpty nodeDataName="footer_url">
    <cms:out nodeDataName="footer_url" var="footer_url"/>
    <cms:ifNotEmpty nodeDataName="footer_name">
       ${footer_url} <cms:out nodeDataName="footer_name"/> 
    </cms:ifNotEmpty>
    <cms:ifEmpty nodeDataName="footer_name">
       ${footer_url} <cms:out nodeDataName="footer_url"/> 
    </cms:ifEmpty>
  </cms:ifNotEmpty>
&nbsp;|&nbsp;

Thanks!
