World: r3wp

I'm not sure if the naming is correct, but I don't care, I need the 
functionality.

Does it handle name spaces?

do you mean this?:

>> print xmltree-to-str third parse-xml {<h:table xmlns:h="http://www.w3.org/TR/html4/">
{      <h:tr>
{        <h:td>Apples</h:td>
{        <h:td>Bananas</h:td>
{      </h:tr>
{    </h:table>}
<h:table xmlns:h="http://www.w3.org/TR/html4/">
  <h:tr>
    <h:td>Apples</h:td>
    <h:td>Bananas</h:td>
  </h:tr>
</h:table>

But REBOL's default parse-xml has limitations, so better use Gavin's 
http://www.rebol.org/view-script.r?script=xml-parse.rif you must 
parse some advanced XML doc's.

Also it's probably possible to use parse instead of the recursive 
function call, but it's working for me so I will stay with this one.

Just note, that if the source xml is using CDATA, the parsed tree 
does not contain this info, so the result would be different.

>> print xmltree-to-str probe third parse-xml+ {<foo>abc <![CDATA[Jack 
& Jill]]> xyz</foo> }
[["foo" none ["abc Jack & Jill xyz"]]]
<foo>abc Jack & Jill xyz</foo>

I'm not sure how to awoid this, but fortunately my XML sources must 
be well formed without CDATA so I'm safe.

Graham, AltXML dom objects have a 'flatten function that renders 
xml.  It preserves namespaces but not whitespace or cdata as cdata 
(though I may do a strict version that does both).

Finally, the work of the W3C binary XML group is an official recommendation: 
http://www.w3.org/TR/exi/

just an interesing fact: the Relax NG Compact schema description 
language is a Rebol dialect if i remove the commas from it.

i tried it on the OAGiS Components.xsd which i transformed to RNG 
and the to RNC using XMLKit

anyone here had issues with receiving Form feed characters in XML 
(which are illegal in XML 1.0) ?
