Hi,
This is, unfortunately, not a feature of the OpenXmlRegex class. It is the most requested feature, but I have not had the opportunity to enhance it to enable this feature.
It is a pretty complicated piece of code to write. Have you watched the screen-casts on OpenXmlRegex? The second screen-cast walks through the algorithm currently implemented for OpenXmlRegex. Unfortunately, that algorithm is not suitable for execution over an entire document – breaking an entire document up into runs of a single character results in too much memory usage. Therefore, OpenXmlRegex does text replacement on a single paragraph at a time.
I have contemplated another approach that would use far less memory, but have yet to prove out this approach.
Cheers, Eric
