Introduction

Are you facing challenges with XML file manipulation using PowerShell? You’re not alone! Many users, especially those returning to coding after a long break or those who are new, find it daunting to work with XML data.

In this guide, we're going to tackle the problem of adding library information to multiple XML files. Imagine having several library XML files, each containing details about books. You may want to specify which library each book belongs to, enhancing the clarity and organization of your data.

Let's dive into how you can efficiently update XML files to include the library name for each book.

Understanding the Problem

Example: Current Structure

Your current XML files look something like this:

The Solution

To achieve the desired outcome, we can use a PowerShell script to iterate through each XML file, load its contents, and append the library name to each book. Here's a straightforward guide to doing just that.

Step 1: Setting Up Your Script

Open PowerShell: Start by launching your PowerShell environment.

Use the following script: This script will loop through each XML file in a specified directory and modify them accordingly.

Step 2: Breakdown of the Script

Loading XML Files: The script begins by setting up a new XML document.

Fetching XML Files: Get-ChildItem retrieves all XML files from the specified path.

Iterating through each Book Element: For each book element in the XML, we create a new <library> element and set its value to the name of the XML file (without its extension).

Appending the Library Node: Each modified book now includes the library name.

Saving Changes: Finally, the modified XML content is saved back to the file.

Step 3: Run the Script

Ensure the path (D:\Test) in the script matches the location where your XML files are stored.

Execute the script, and your files will be updated with the library names as intended!
