## Description

How to get the XML of Word (.docx) documents and compare their contents using Visual Studio.

## Solution

The .docx file format is an archive that can be unzipped. This gives several folders and files with the document contents, styles and other settings. To access the content, you can find and open the **document.xml** file. Then, you can compare the text in the **document.xml** files of the corresponding files.

This article describes how to do this using the [Open XML Package Editor for Modern Visual Studios](https://marketplace.visualstudio.com/items?itemName=bsivanov.OpenXMLPackageEditorforVisualStudio) extension tool for easier access to the files of the .docx file, without the need to unzip it. Visual Studio built-in diff tool can be used to compare the extracted XML contents.

1. Install the [Open XML Package Editor for Modern Visual Studios](https://marketplace.visualstudio.com/items?itemName=bsivanov.OpenXMLPackageEditorforVisualStudio) Visual Studio extension. This will allow you to open the **.docx** files content directly in Visual Studio.

2. [Create a new Blank Solution](https://learn.microsoft.com/en-us/visualstudio/get-started/tutorial-projects-solutions?view=vs-2022#create-a-solution) in Visual Studio. This is required in order to use the Visual Studio's [Compare Selection](https://learn.microsoft.com/en-us/visualstudio/ide/compare-with?view=vs-2022) feature.

3. Include the two **.docx** files that will be compared in the solution.

4. Create two new empty **.xml** files in the solution.

5. Double click the first **.docx** file in the solution and open the **/word/documents.xml** file.

   If the file is not formatted you can do that by using the **Edit-->Advanced-->Format Selection** option. The default shortcut for this action is **Ctrl+K, Ctrl+F**.

6. Copy the content of the **documents.xml** file to one of the empty **.xml** files and save it.

7. Repeat **step 5** also for the other **.docx** file and copy its XML contents to the other empty **.xml** file, and then save it.

8. Select the **.xml** files in the Solution Explorer and right click on any of the files to display the context menu. From the menu select the [Compare Selection](https://learn.microsoft.com/en-us/visualstudio/ide/compare-with?view=vs-2022) option.

This will open a new diff view showing the comparison between the two **.xml** files
