I am brand new to SOAP and XML. I am proficient with CFML. I need to request information from a hotel reservation webservice and store the response in a MS Access database to be used by my CFML application. I will be translating to mySQL later in the development of the application.

Below is the XML code that I received from the webservice provider:

Technical information

The Hotel interface runs onto HTTP protocol and both Xml request and responses should be into a SOAP message. This way allows multiple Xml functions in the same message and save in communications. But the main advantage is that SOAP offers many integration possibilities with many systems using free and available libraries by Internet. In any case the SOAP tags are optional and can be omitted.

See Soap-tags below:

How do would I communicate with the web service to comsume the information in the XML request. How do you format the request to the web service to get the response. The code is the samples that were supplied to me by the web service.

I am still trying to get my head around ColdFusion, so any suggestion may be slightly off base, but I have seen articles like this (using cfinvoke to interface with web services):

How to invoke a Web Service while omitting optional service method arguments
http://www.talkingtree.com/blog/index.cfm/2006/7/12/cfinvokeargument-omit-attr

It would be helpful to know what the web method signature looks like, rather than the request/response structure.

After doing some research I tried the code below to send a request to the web service and recieved the following error message:

The XML page cannot be displayed
Cannot view XML input using style sheet. Please correct the error and then click the Refresh button, or try again later.

In your request, I don't see the <barceloDS_requests> element.
