I'm using libsoup, libxml2 and libxslt.

Libsoup grabs the file and I do:

xsltStylesheetPtr cur = NULL;
xmlDocPtr res, rss;

rss = xmlParseMemory(msg->response.body, msg->response.length);

>From there,

params[nbparams] = NULL; 
xmlSubstituteEntitiesDefault(1);
xmlLoadExtDtdDefaultValue = 1;

cur = xsltParseStylesheetFile((const xmlChar *)"rss2html.xml");
 
res = xsltApplyStylesheet(cur, rss, params);


After the 
rss = xmlParseMemory(msg->response.body, msg->response.length);

The xml tree appears the same as the source file.  The problem occurs in
the following situation:

<description><![CDATA[&quot;One says definitely, the other says maybe.
At this point, the Nets will take whatever they can
get. . .&quot; ]]></description>

After a the stylesheet is applied, the &quot; are turned into
&amp;quot;.  Some of the CDATA has " which come out ok in the eventual
html.    

All the template do is grab the <title>,<link> and <description> then
throw the values into an html <table>.

Does that make it more clear?
