A very newbie question, what are these keywords
|
|
|
| I am quite new to BizTalk. I always see people using keywords like
'construct','xpath()' and all the others in the orchestration expression
shapes in writing scripts, I have no idea what that is about and didn't find
anywhere tell me what that is as well. Could someone please tell me please?

When you use the Orchestration designer to create an orchestration, you're
using just that: a designer. The designer actually generates real code in a
language called XLANG/s in BizTalk 2004/6, which is then converted into C#
and compiled down to a .NET assembly when you compile your biztalk project.
When you write code in your expression shapes, you're actually writing
XLANG/s expressions, which are somewhat similar (rather, look similar) to
C#, but really isn't.
The xpath() function is one of those keywords/functions available in
XLANG/s, which allows you to evaluate an XPath expression on a biztalk
message.
As for the rest, here are some good articles on the subject:
