What steps do I need to take to use TBXDS?
When you're investigating the possibility of using
the TBXDS service for retrieving quotes, you will have
to consider the following points:
-
Knowledge of XML (XML DOM, XPath) is vital.
-
Availability of a conforming XML parser library
(or COM object like MSXML, pre-installed on
almost all Windows platforms with the Internet
Explorer).
-
HTTP-library to send HTTP-POST messages, and
receive data. (An all-in-one solution is, for
example, the MSXML distribution, which includes
an XMLHTTP COM object).
-
A local storage location for the received data;
for quotes this can be a simple database, but
it's also possible to save the received XML
(or parts thereof) as a local file.
-
A schedule for regularly requesting the TBXDS
data. For quotes, an interval of each 10 to 15
minutes is more than adequate.
-
A solution of displaying the stored data
dynamically in your web page (e.g., ASP, PHP,
ColdFusion, JSP, etc.) But you could also
generate a static HTML page every time you
receive the quote data.
