Tersus: Re: Is this possible...?

Re: Is this possible...?Date: Jul 19, 2008Tags:XMLUsing web services not defined by WSDLDefining web services through WSDL and using them though SOAP is a standard supported by Tersus, but is not the only way to use web services.Tersus also supports acquiring data from another server without using WSDL-defined web services.You can follow such an implementation in the Examples projects provided with the Tersus Studio:

Look at the package 'Examples/Web Services/Web Services - Forex/Load/Load'. This view loads exchange rates from the site of the Bank of Israel.

The data (in XML) is read from http://www.bankisrael.gov.il/currency.xml.

If you look at the modeling of the 'Load' button, you will see a very simple modeling that first read the XML file through 'Read Resource' and then parses it (through 'Parse XML').

Note 1:'Parse XML' gets as input an XML file, and its output is a data structure whose field hierarchy corresponds to the structure of the XML file.In the case of the exchange rates provided by Bank of Israel, the way to model this data structure was very simple - we downloaded the file and created the corresponding Tersus model through the Import XML Example wizard.If there is an XML Schema for the XML file you access, you can use the Import WSDL wizard. Note 2:You can also use 'HTTP Post' to post a request to a server returning an XML document as a response. Then parse the response through 'XML Parse', as before. the Examples projects includes an example of using 'HTTP Post' - see the button 'Post Test' in the view 'Direct Payment' ('Examples/Web Services/Web Services - PayPal/Direct Payment/Post Test/Post Test'). Getting feeds from Indeed.com:I suggest you start by figuring out what is their way to access the information. I would start at their Web Services page, which says they use XML format. See Also:
