Search metadata for empty values

[KingSwitcher]

I need to create a routing condition that requires all metadata fields to have a value (not empty).
The metadata list can vary depending on the submit point, so I need a solution that is able to search through all levels of <value></value> elements.
I'm learning Xpath expressions and it looks like that's where this solution is headed but any guidance would be much appreciated!

You can setup the submit point fields to require a value so that they can't be empty.

Well, you mentioned you're learning xpath. Wouldn't something like this work?

Code: Select all

count(.//field/value[string-length(text())=0])

But like jan_suhr said, your problem can be solved marking the field as required.

I need the option to leave fields empty.
That's why I need a condition to route the job to a different checkpoint if any fields are left empty.

Thanks. I modified it a bit, but it worked!

Code: Select all

count(//value[string-length(text())=0])

Glad I could help.

Just so you know, I used //field/value because only //value could count values that are not related to fields, if they exist.

Understood. Thanks!
