The returned document is XML 1.0 compliant formatted data using the same structure as the other Co-Servers, only with an XML format.

The XML Support in ScreenSurfer also includes full drill-down access into an input XML document to enable processing of documents containing data of arbitrary complexity, such as a complete multi-line order.

There is no component to download in an XML environment--the caller is simply one which has the ability to pass XML input over an HTTP connection and parse and process the returned XML-formatted results.
At the ScreenSurfer side, a facility in the <TESECTION> tag has declared a "transaction path". A transaction path is a URL specification that enables ScreenSurfer to associate a specific URL with a SurferScript section. Using the declared paths, ScreenSurfer connects the request from a Co-Server with the corresponding SurferScript.
With ScreenSurfer V3, the Visual Surfer Wizards can be utilized to define screen identification, navigation and fild mapping. Then, the Visual Logic Editor can be used to construct a visual representation of the logic to support the transaction, including full session pool management.

ScreenSurfer's Remote Procedure Call
Once a transaction has been defined and associated with SurferScript in the <TESECTION> tag, the ScreenSurfer developer uses a number of specific host session actions (using the <TEACTION> tag) to connect to a session, navigate to information and then read information from the screen. When using Visual Surfer, this step is replaced with a drag-and-drop definition of logic components.

Result Data
The ScreenSurfer developer is able to quickly define the returned data elements (along with the names of those elements) using the <TEDECLARE ROW> tag. The row that is defined can then be returned as either a simple set of values or as a table consisting of multiple rows. Each call from the client, whether it originate from a ColdFusion CFX tag or an ASP Component, can have multiple results returned. When multiple results are returned, each is given its own QUERY Result in ColdFusion and its own RecordSet in the SSurfer.ASPRequest component.

Defining a row of data enables the return of named data elements to the co-server application. In addition ScreenSurfer supports "passing-through" any SurferScript HTML possible in a direct ScreenSurfer connection. This enables the SurferScript author to provide entire, properly formatted screens (or areas of screens) to the co-server applicaition as a single attribute of a query/recordset. This is achieved using the <TERESULT HTML> tag.
