The following function will return XML as a string:

CREATE FUNCTION "DBA"."UNBlacklist"() returns long varchar url 'http://www.un.org/sc/committees/1267/consolidatedlist.xml' type 'HTTP:GET' ;

To extract stuff from it, use select ... from OpenXML().

@Dmitri, thank you. Any comment on the usage of the "proxy" keyword? Is it possible to pass the network username/password authentication?

Never tried it before, but adding

proxy 'http://192.168.0.1:3128'

seems to work. For the authentication, try adding user:password before the URL, e.g.:

CREATE FUNCTION "DBA"."UNBlacklist"() returns long varchar url 'http://proxyuser:proxypwd@www.un.org/sc/committees/1267/consolidatedlist.xml' type 'HTTP:GET' proxy 'http://proxyserver:proxyport' ;

On a second thought, 1) How to pass website authentication info? 2) How to pass network proxy authentication info?

I think the following format will work, e.g: CREATE FUNCTION "DBA"."UNBlacklist"() returns long varchar url 'forumuser:forumpwd@www.someforum.com' type 'HTTP:GET' proxy 'networkuser:networkpwd@proxyserver:proxyport';

I dont know whether this will work. No need of this in the sample case above. I will try to download something which requires a web-login.

Just as a quick start:

You should be able to download any web document with SA's web client procedures/functions.

I haven't done that myself so I can't give exact advice but you may have a look at the topics "SQL Anywhere web services" and "Web service clients", e.g. the following topic.

Some ideas:

You could code the URI in a web client function
The function could return the according XML document
Or you could use SA's XML support to extract the needed information from the document directly
Calling the web client function regularly could be done be an event or the like.

Just my thoughts
