Demonstrates how to use regular expressions with WordWriter to easily search and replace text. |
This sample uses the WordApplication class to open an existing document on the server and perform search and replace actions on it. First, view the stored document to determine which patterns to search for (search terms that work well are WordWriter, and template). Remember that Regular Expressions are case sensitive. So, to search for "WordWriter" "Wordwriter", use this pattern: Word[Ww]riter.
