Conditional Statement with Null Value - CoryPalme

I have a field that I need mapped to the output xml if it is not null.
Otherwise, I need to run a custom assembly and map the returned value from
that assembly to the output xml.

I can not seem to accomplish this.

Can someone else explain what I need to do to get this to work?

Thanks,
Cory

use something like.. in your assembly code (in helper class)

myFunction(strung inputValue ,...)
if (inputValue == null)
return null;

make sure the high-level nodes do not interfere the mapping

Hi Cory,
I think it is best to use inline C# code as below:

if(null)
call external assembly
else
map the field value

using other ways I am afraid will have to modify your external assembly.

So basically have one input parameter and do the following:

if (param1 == null)
{
val = externalassembly(param1);
return val;
}
else
return param1;

Whatever I return will be mapped to the output field?

Thanks,

Since the node looks like this when there is no value<node1 />, would I be
able to use the IsString functiod to check if there is a value?

use the length function like this...
param1.trim().length() == 0;

If use the string parameters it can save a lot of time.
