Understanding the Challenge: How to Extract Data from Workday XML Using XPath

As the complexity of data sources increases, so does the need for effective querying methods to pull precise information from structured data formats such as XML. In this guide, we will tackle a common scenario faced by professionals utilizing Workday's data API: extracting a specific value from an XML response using XPath.

If you've just encountered Workday's XML structure and you're feeling overwhelmed, you're not alone! The intricacies of XPath, combined with namespaces and datatype attributes, can be challenging. But fear not, we're here to simplify it for you.

What Is XPath?

XPath (XML Path Language) is a query language that allows you to navigate through elements and attributes in an XML document. It plays a crucial role in data extraction, especially when working with APIs that return XML-formatted data.

The XML Structure

Let's take a look at the XML response that we need to work with:

In this XML, we are interested in extracting the value Some_Value located within the <wd:ID wd:type="Job_Classification_Reference_ID">.

The Goal: Extracting a Specific Value

You want to retrieve the value of wd:ID where:

The wd:type attribute is equal to Job_Classification_Reference_ID

The corresponding WID is 6abcdefghijklmnopqrstuvwxyzabcd2

The Solution: XPath Expressions

Using Namespace Prefixes

If you are in a position where declaring a prefix is possible, use this XPath query:

Conclusion

Navigating through Workday's XML structure using XPath can seem daunting at first. However, by understanding the XML layout and utilizing the correct XPath expressions, you can extract specific data with ease. Whether you opt for prefixed queries, explicit paths, or local name solutions, you now have the tools to successfully query Workday XML data.

As you continue your journey into data extraction, don't hesitate to experiment with these XPath expressions to find what works best for your needs.

Happy querying!
