Search for Multiline patterns – OpenXmlRegex

[meronfParticipant]

Hello,
Is there an option to replace multiline string that match a pattern that starts with ** and ends with ** with empty string. The content between the ** can contains any type of content, paragraphs, line brakes, images, etc. and should dropped from the document in case it surrounds with **.

I tried the OpenXmlRegex with the following pattern:
regex = new Regex((@”\*\*(.*)(\n)?(.*)?\*\*”), RegexOptions.Multiline | RegexOptions.IgnorePatternWhitespace | RegexOptions.CultureInvariant);

But it works only for text content in the same line.

Any idea how can I achieve such request?

Thanks,
Meron

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
