How to Parse XML Using VBA: A Beginner's Guide 📝🔍🔎

Are you a VBA developer who is stuck trying to parse XML data? Don't worry, you're not alone! Many VBA developers face this challenge, especially when they are limited to working with older technologies like VB6 and VBA.

In this blog post, we will walk you through a step-by-step guide on how to parse XML using VBA. We will address the common issues developers face and provide easy solutions to help you extract the data you need. Let's dive in! 💻🧐

Understanding the Problem 🤔

Before we jump into the solution, let's take a moment to understand the problem at hand. You have an XML string that looks something like this:

<PointN xsi:type='typens:PointN' 
xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' 
xmlns:xs='http://www.w3.org/2001/XMLSchema'>
    <X>24.365</X>
    <Y>78.63</Y>
</PointN>

Your goal is to extract the values of X and Y into separate integer variables. But since you're new to XML and limited to VB6 and VBA, you're unsure of how to achieve this. Let's move on to the solution! 💡🚀

Solution: Parsing XML Using VBA 🛠️📚

To parse the XML string and extract the values of X and Y, you can use the Microsoft XML, v6.0 library. Here's a step-by-step guide to help you achieve this:

1. Add a Reference to the Microsoft XML Library 📚

   • Open your VBA editor (ALT + F11) and go to the Tools menu.

   • Select References and look for "Microsoft XML, v6.0" in the list.

   • Check the box next to it and click OK to add the reference.

2. Declare Variables and Create XML Document Object 📓✍️

   • In your VBA code, declare two variables to hold the extracted values:

     Dim xValue As Integer Dim yValue As Integer

   • Next, create an XML document object and load the XML string into it:

     Dim xmlDoc As New MSXML2.DOMDocument60 xmlDoc.LoadXML "<PointN xsi:type='typens:PointN' " & _ "xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' " & _ "xmlns:xs='http://www.w3.org/2001/XMLSchema'>" & _ "<X>24.365</X><Y>78.63</Y></PointN>"

3. Extract Values from XML 📝🔍

   • Now that you have the XML document object, you can extract the values of X and Y using XPath:

     xValue = xmlDoc.SelectSingleNode("//X").Text yValue = xmlDoc.SelectSingleNode("//Y").Text

4. Voila! Use Your Extracted Values! 🎉💪

   • Congrats! You have successfully parsed the XML string and extracted the values of X and Y into separate integer variables.

   • You can now use these values in your VBA code as needed.
