REST driver output transform - token-replace-all regex &

[fergubru]

I'm trying to massage the output of the REST driver with an output transformation policy, one of the issues I'm having is with this DirXML tag:

<token-replace-all regex="("\],)" replace-with="&">

This winds up in the output document as &amp; - this is commonly done to render xml to html so that a simple '&' is displayed on the final web page.

However, it's going as-is into the rest query, causing every form entry after the first to have an erroneous 'amp;' as a prefix. (the first ampersand & code is properly seen as an entry delimiter, leaving the remaining amp; orphaned and treated as part of the name of the next key), like this:

<key>=<value>&<key>=<value> etc.

(raw code of the above is <key>=<value>&amp;<key>=<value>)

whereas the expected behavior is:
<key>=<value>&<key>=<value> etc.

(raw code of the above is <key>=<value>&<key>=<value>)

Is there a way to render just '&' in the output document, or to remove the additional 'amp;' once it is in the variable?

Managed to figure this one out, it had nothing to do with the replace token. The above token was nested within a token-XML-serialize token that proved not to be necessary in this use case. With that parent element removed, & produced the expected value in the output document.
