How to Remove Namespace from XML Nodes in SQL Server

Working with XML in SQL Server can often lead to scenarios where you need to manipulate namespaces for various reasons. One common problem users face is the requirement to strip namespaces from child nodes while keeping the root node intact.

In this guide, we will go through a specific case where a user has encountered this issue and how to effectively resolve it. By the end, you will have a clear understanding of how to manage XML namespaces in SQL Server using T-SQL.

The Problem

The problem arises when executing a T-SQL query that generates XML output. In the provided example, the user has a valid query that correctly generates XML, but they notice that child nodes contain unwanted namespaces. Here's the essential output that represents the problem:

The Solution

The solution involves a few changes to the original query. Here is a step-by-step breakdown of how to approach this problem:

1. Declare an XML Variable

Start by declaring an XML variable that collects the Adr nodes without the namespace. The below syntax achieves that by utilizing the FOR XML PATH query option.

This will generate the Adr XML elements without applying any namespaces to them.

2. Modify the Main Query

Next, incorporate the declared variable into the main XML generation query. By including the @ Adr directly in the SELECT statement, you preserve its namespace-less structure while retaining the desired attributes and root node namespace. Here’s how you can structure this:

3. Result

The output from this modified query will yield the desired XML structure with the Adr elements without a namespace, while keeping the root element namespace intact.
