Re: small grouping task

I have a grouping task I am having trouble wrapping my mind around.

I need to change some <input>'s into <li>'s but the <input>'s don't wrap what the <li>'s have to.

Want to give it a try?

T:\ftemp>type fred.xml
<div>
<p>text</p>
{surronding xhtml}
<p class="problem">{some xhtml with no inputs}
  <input type="radio" /> <span class="p">a</span><br />
  <input type="radio" /> <span class="p">b</span><br />
  <input type="radio" /> <span class="p">c</span><br />
  <input type="radio" /> <span class="p">d</span><br />
{some xhtml with no inputs}
</p>
{surronding xhtml}
</div>

T:\ftemp>call xslt fred.xml fred.xsl
<?xml version="1.0" encoding="utf-8"?>
<div>

   <p>text</p>
