XML entities and Roller output

[Stephen Winnall <st...@winnall.ch>]

I am trying to integrate Roller 3.0 with Cocoon for my website. The  
Roller output is passed to Cocoon, which expects pure XML. 99% of the  
time, this is no problem. However, when I send Roller a request like

	http://localhost:8888/blog/en/category/General

I get code back which contains an unescaped ampersand. The following  
is a snippet from the top of the Roller calendar:

<table cellspacing="0" border="0"  summary="Blog Archive Calendar"  
class="hCalendarTable">
   <tr>
     <td colspan="7" align="center" class="hCalendarMonthYearRow">
       <a href="/roller/en/?cat=General&date=200701" title="Prev"  
class="hCalendarNavBar">&laquo;</a> February 2007
     </td>
   </tr>

Any XML processor is likely to complain about the href because it  
sees "&date=" as a syntactically incorrect XML entity. What an XML  
processsor needs in this situation is "&amp;date=" or the URL-escaped  
variant "%26date=".

After looking at the source, I think the problem is in

	getQueryString in org.apache.roller.util.URLUtilities

getQueryString just outputs a plain "&", with no options for other  
formats as far as I can see.

Is there any way of telling Roller to generate 100% pure XML (or at  
least an &amp; or the URL-encoding in this case)?
