How to make text unconditional

Question

Hi.
I am writing a program to delete condition tag.
But if any text is tagged with the tag I'm deleting,
I need to make the text unconditional.
Can some one tell me how to do this?
Best regard

Hi erieru103,
This seems like it should be a simple task, but it reality it is very complex. The problem is that (to my knowledge) there is no built-in way to do this with the FDK. All you have to work with are objects and properties. With conditional text, it is particularly difficult because conditional settings can differ from one character to the next.
Here is a function that I use to remove a condition from a document; that is, remove any place that it is applied (the condition remains as part of the template). It works; however, it is technically incomplete because it might remove other conditions as well. Basically, it seeks out any instance of the condition and makes that text completely unconditional. Then, it steps through every table row in the document and un-conditionalizes it. It may not be exactly what you want, but perhaps it will give you some kind of lead on where you really want to achieve.
