Extract from one document- replace in another document w/first document's content

I’m currently evaluating the ASPOSE.WORDS tool and I would like to extract content from one document and replace tags in another document with the content I extracted. The content could contain text and/or an image.
The ExtractContentBetweenBookmark() method looks pretty straight forward as to retrieving the content from the source document, but how would I persist 4 or 5 bookmarks worth of content and then loop through the source document looking for tags and performing replace?

Hello
