How to extract content between hidden text using C#

Hi,
I want to take content between hidden items(or invisible items). For each paragraph under heading has a one or two paragraph. Each paragraph starts with a hidden word and ends with a another hidden word. I as show in the sample.

As you can see in the uploaded sample, |p| or |r| will be the opening word for the paragraph, and |/p| or |/r| will be the ending word for the paragraph.

I want to get the paragraph between the hidden words. Please help me to find a way for this feature.

In your case, we suggest you following solution.

  1. Find the start tag e.g. |p| or |r|.
  2. Move the cursor to this matched node and insert BookmarkStart node.
  3. Do the same for end tag and insert BookmarkEnd node.
  4. Extract the content from bookmark.
