Subject: String replacing help

I'm working with Mechanize doing some screen scraping. Because of the
project, I have to use an older version of Mechanize for now, I'm using
0.8.4.

The goal of what I'm trying to do is take a string and insert pipes '|'
before words that are *not* inside of <a></a>.

I have:
>> template_body.class
=> Hpricot::Elements
>> template_body.to_html
=> "<pre><a href=\"javascript:document.f6.SLID.value='F36';
document.f6.submit();\" onMouseOut=\"window.status='';\"
title=\"Select\" onMouseOver=\"window.status='Select'; return
true;\">HEAD</a>&nbsp;\n  <a
href=\"javascript:document.f6.SLID.value='F37'; document.f6.submit();\"
onMouseOut=\"window.status='';\" title=\"Select\"
onMouseOver=\"window.status='Select'; return true;\">TITLE</a>&nbsp;<a
href=\"javascript:document.f6.SLID.value='F38'; document.f6.submit();\"
onMouseOut=\"window.status='';\" title=\"Select\"
onMouseOver=\"window.status='Select'; return true;\">\"test\"</a>\n<a
href=\"javascript:document.f6.SLID.value='F39'; document.f6.submit();\"
onMouseOut=\"window.status='';\" title=\"Select\"
onMouseOver=\"window.status='Select'; return true;\">BODY</a>&nbsp;\n
<a href=\"javascript:document.f6.SLID.value='F40';
document.f6.submit();\" onMouseOut=\"window.status='';\"
title=\"Select\" onMouseOver=\"window.status='Select'; return
true;\">DIV</a>&nbsp;id&nbsp;<a
href=\"javascript:document.f6.SLID.value='F41'; document.f6.submit();\"
onMouseOut=\"window.status='';\" title=\"Select\"
onMouseOver=\"window.status='Select'; return true;\">\"main-div\"</a>\n
<a href=\"javascript:document.f6.SLID.value='F42';
document.f6.submit();\" onMouseOut=\"window.status='';\"
title=\"Select\" onMouseOver=\"window.status='Select'; return
true;\">CSS-WITH-LINK</a>&nbsp;destination&nbsp;<a
href=\"javascript:document.f6.SLID.value='F43'; document.f6.submit();\"
onMouseOut=\"window.status='';\" title=\"Select\"
onMouseOver=\"window.status='Select'; return true;\">TO</a>&nbsp;<a
href=\"javascript:document.f6.SLID.value='F44'; document.f6.submit();\"
onMouseOut=\"window.status='';\" title=\"Select\"
onMouseOver=\"window.status='Select'; return true;\">:index</a>\n
<a href=\"javascript:document.f6.SLID.value='F45';
document.f6.submit();\" onMouseOut=\"window.status='';\"
title=\"Select\" onMouseOver=\"window.status='Select'; return
true;\">IMAGE</a>&nbsp;source&nbsp;<a
href=\"javascript:document.f6.SLID.value='F46'; document.f6.submit();\"
onMouseOut=\"window.status='';\" title=\"Select\"
onMouseOver=\"window.status='Select'; return
true;\">RENDER</a>&nbsp;image&nbsp;<a
href=\"javascript:document.f6.SLID.value='F47'; document.f6.submit();\"
onMouseOut=\"window.status='';\" title=\"Select\"
onMouseOver=\"window.status='Select'; return true;\">@image</a>\n
max-height&nbsp;<a href=\"javascript:document.f6.SLID.value='F48';
document.f6.submit();\" onMouseOut=\"window.status='';\"
title=\"Select\" onMouseOver=\"window.status='Select'; return
true;\">m-h</a>\n</pre>"


The words I'm trying to insert the pipe before have a non-breaking space
tags around them. I had it working where I can iterate through
everything and return a new string, but I end up losing all line breaks
and non-breaking spaces using

 new_body = ''
      template_body.to_html.split("&nbsp;").each do |el|
        el.split("\n").each do |e|
          unless e.empty? or e =~ /<\/?[^>]*>/
            e = '|' + e
          end
        end
        new_body += el
      end


Any ideas?

Thanks,
~Jeremy
