Re:  Is this possible using XSLT?
Maybe you can match on @lefparen != "" and use a recursive function to open a <paren> tag for each "(".

In the function you also process your bar tags and return when @rightparent = ")"

Too lazy to try to write real code, but I think it may work.

Hello,

Is it possible to get XSLT to transform XML that looks
like this:
<foo>
    <bar leftparen="((" rightparen="" num="3" oper="*"
/>
    <bar leftparen="" rightparen=")" num="2" oper="-"
/>
    <bar leftparen="" rightparen=")" num="2" />
</foo>

into something that looks like this:
<foo>
   <paren>
     <paren>
       <bar num="3" oper="*"/>
       <bar num="2" oper="-"/>
     </paren>
     <bar num="2"/>
   </paren>
</foo>

"paren" elements are opened and closed based on the
number of '(' in each element's leftparen and
rightparen attributes.
Can anyone help?
Thanks,

Rob
