How to Bulk Replace Values in XML File Using Notepad+ +

If you frequently work with XML files, you may find yourself in situations where you need to make bulk updates efficiently. One common task is to copy the value of one tag to another tag across multiple instances in an XML file. This can be particularly tedious if done manually. In this post, we'll explore how you can quickly perform this operation using Notepad+ + and XSLT (Extensible Stylesheet Language Transformations).

Understanding the Problem

Imagine you have an XML file that contains multiple entries, each with a <name> and a <description> tag. Sometimes, the <description> tag needs to reflect the same value that is present in the <name> tag.

Example

Old XML Structure:

As you can see, we want to replace the content of the <description> tags with the corresponding <name> tags. Let's look at how we can achieve this using Notepad+ + .

The Solution: Using XSLT in Notepad+ +

Step 1: Prepare Your Environment

Make sure you have Notepad+ + installed with the XML Tools plugin. If you don’t have the XML Tools plugin:

Open Notepad+ + .

Navigate to Plugins in the menu.

Select Plugins Admin.

Search for XML Tools, check it, and click on Install.

Step 2: Input Your XML Data

Open your XML file in Notepad+ + and ensure your XML structure is formatted correctly.

Step 3: Create Your XSLT

You will create an XSLT stylesheet that performs an identity transformation, changing only the <description> elements. Below is the XSLT code you need:

Step 4: Perform the Transformation

Go to Plugins XML Tools XSL Transformation....

In the dialog, paste your XSLT code into the XSLT text area.

Click Transform.

Step 5: Review the Output

After running the transformation, your output should reflect the changes where all <description> tags now mirror their corresponding <name> tags:

Conclusion

Using Notepad+ + and XSLT for bulk updates in XML files can save you significant time and reduce the likelihood of errors associated with manual editing. By following the steps outlined above, you can efficiently copy values between XML tags as needed.

Don’t forget, XSLT is a powerful language that can be adapted for more complex transformations as your needs evolve.
