Find a text in a document and replace the text by appending a document

We are currently using the MS word automation and using the find execute method to find the text and get the range. Then we append another document to that position.
We are trying the same with Aspose and not sure if this is possible. We are able to find the text, but not sure if we can append a document by replacing the text.

Thanks for your inquiry. Of course you can achieve this using Aspose.Words. Please see the following link to learn how to insert one document into another.
Also I think information provided in the following forum thread could be useful for you.
Please let me know in case of any issues, I will be glad to help you.
Best regards.
