XML SOAP response

There were a couple of questions in there so I'll try to address them all (let me know if I miss any).

 

 

1 Determining availability

 

First, to determine if no servers are available, you could code an iRule to check the value of "active_members" and if that's 0 you can custom build a response and send it with the HTTP::respond command.

 

 

2 Extracting info from the submitted request.

 

This can be done in a couple of ways and since I don't know the data you are extracting or it's location in the request it's hard to suggest whether regular expressions or string searches would be your best options.

 

 

3 Is there a general purpose XML-Parser?

 

Yes, there is the XML profile that allows for parsing of XML requests in a stream fashion. Check out the XML_* iRule events. Keep in mind that this is a request-only filter at this point and there is no way from within an iRule to craft an XML reponse with this XML parser. You'll have to custom build the string yourself and send it back with a HTTP::respond.
