Scan visibility conditionnal formulas in .net

Hello,

in my enterprise we've got a tools wich can scan all our reports (rpt files in a directories) in order to find database objects (table, view, procedure, etc.) or string.

This tools is very usefull to know the consequences of a development or a database modification.

In the rpt files we programmatically scan objects, formulas, parameters, request and selection formula

Recently we've noticed thant this tool don't consider conditionnal formula, especially the formulas used to define if a section is visible or not. (I think it's the same for visibility conditionnal formulas of report objects)

In order to correct this omission, I look into report document object model, but I can't find anything (none into formulafields none into reportdefinition.areas sections)

Is it possible (I hope so)

How ?

Thank you

Yoann
