If you want to parse a general tooltip string, you have to find
documentation on which FDO SQL constructs are avalible.
You will most likely spend a lot of time on this, since it includes
tokenization, operator precedence and other parsing aspects.
It is not parsed by the javascript.
The FDO library can be imported in C# (.Net 2.0+), and you should be
able to get the FDO library to parse it for you.
An easier approach would be to try giving the expression to a select
statement executed on the datasource.
I have not tried this.
If you get it to work, it would be great if you shared your findings.

Hi folks,
I have a .NET application using mapguide and I want to get the information
from a layer tooltip field out as a string and parse it. I have now got to
the stage where I can read the XML definition of the layer and pull out the
ToolTip and URL as strings in my C# code
So, as an example, in the XML layer definition I have
<ToolTip>concat('http://www.testurl.com/Documents/PDFs/', concat("Name",
'.pdf'))</ToolTip> and I want to display
http://www.testurl.com/Documents/PDFs/blah.pdf in my code. (yes I know
that's a URL but you get the point).
Has anyone written a function in c# to parse this? I'm assuming it's some
kind of FDO language that has the concat functions etc, but now I think on
it, could it be that javascript parses it automatically?
Any help much appreciated!
Ross
