How to generate a Word document without installing word

This is our requirement.

1. There is a template for such a Word document as follows:

2. We need to dynamically generate such a file on the server. Each time we need to change the content to the title, description, and time. Read the employee list and fill it in the following table.

 

 

Our solution is:

1. Install word on the server, and then operate and generate documents by using the com model of word, such as Word. Application and word.doc ument.

The problem with this method is that the server must install word, which may be impossible for many customers.

 

2. generate WORD Documents in XML format. This is what this log describes.

 

First, we will complete all the Word documents, including the format settings. As shown in.

Next, we will save the document in XML format

What about this document?

It looks messy, right? It doesn't matter. Let's take a look at the relevant architecture.

Open the file in IE. Delete the following sentence first.

In order to quickly modify and expand the document later, we add several tags to the XML element of the previously written text.

We added several tags

Tag = "title" indicates the title

Tag = "Description" indicates the description.

Tag = "time" indicates the time

Tag = "table" indicates the row of the table.

Tag = "firstname" indicates the surname

Tag = "lastname" indicates the name

Tag = "country" indicates country

Tag = "region" indicates the region

Tag = "city" indicates the city

Then, we need to write down a namespace

Xmlns: W ="Http://schemas.microsoft.com/office/word/2003/wordml"

 

Okay. With these materials, we can modify the file on the website.

 

We use a separate ashx to generate the file.

Next, in the page, our code is

 
Protected VoidBtgenerate_click (ObjectSender, eventargs e ){// Generate a Word document based on the template. The replaced part includes the title text, description text, and table.Response. Redirect ("Kerberenthandler. ashx");}
 

 

The final running result is as follows:
