I have created an iterative macro for parsing an XML field in a table into a flattened format but I'm having a bit of trouble finishing it off.
The issue arises as not every record has all of the fields, so when I try to use a select tool within the macro, if the field doesn't exist in that specific record, I get a "no valid field was selected" error and the macro fails. Does anybody have any idea on how to fix this?
To parse this I used xml parse on the field looking for the child element <airline> and returning the outer xml. I then used the select tool to filter to just the outer xml field and another xml parse tool to get the child elements id = foo, name = bar. I can't just use a single xml parse tool specifying "specific child name" = "id" as there are multiple id fields in the document.
My issue comes when I try to parse an iteration where there are no elements called <airline>, the select tool doesn't find airline_outer_xml as a field and erros, failing the macro.
Any help would be much appreciated!
(The area where my workflow breaks down. The top tools are when it's working i.e. <airline> exists in the document, the bottom is where it fails i.e. when <airline> does not exist)
It would be best if you could send the file in which you are implementing the macro. If you send the zipped file (exported the way I describe above) it should include the macro itself and any template data.
And I totally understand about not wanting to share sensitive data-- any sample data would help, as long as I can recreate the problem.
