Re: Correctly translate XML invalid characters via SQL to make an HTTP call

Hi all,

There is an issue a can't find a solution to. I have searched the archive
and other sources without success, meaning the issue is probably an issue
only to me.

Is there a way to add a CDATA content using SQL XML functions?

The program I am working on creates an XML body content for an HTTP request
to call a provider's API via HTTPCLOBVERBOSE function from
systoools library.

To create the XML body I add lines like this:

xmlelement(name "RagioneSociale", trim(bor.ORAGDE))

to an SQL xmlserialize select. If the database field contains the ampersand
symbol (' F.LLI COMENSOLI & OLIVARI SAS') the result is this:

<RagioneSociale>F.LLI COMENSOLI &amp; OLIVARI SAS</RagioneSociale>

meaning the SQL functions for XML already translate the invalid XML
characters.

Now, when the call is made, the API rejects the XML as invalid.

If the very same request with the very same body is done through Postman,
it works, because I discovered it translates the &amp; entity into %26.

Instead of focusing on & symbol only, I thought the easiest solution is to
embed these few database fields into a CDATA section so that the final line
should look like this:

<RagioneSociale><![CDATA[F.LLI COMENSOLI & OLIVARI SAS]]></RagioneSociale>

but I don't know how.

I can't manually concatenate the database field with the CDATA section,
because < and > signs will be automatically translated in their entity
counterparts as well, and an XMLCDATA function or similar is not available
on the system (or on my system).

I would like to avoid the use of %scanrpl function because when it comes to
applying to a long varchar field it takes a lot to execute.

Would you have any suggestion to cope with this?

Thank you very much
