Resolving XSLT 3.0 Stylesheet Compilation Errors with Accumulators

When working with XSLT (Extensible Stylesheet Language Transformations), especially version 3.0, encountering compilation errors can be frustrating. In this guide, we will address a common issue related to the use of accumulators, which are helpful for maintaining a running total or count during XML transformations.

The Problem

You might be trying to transform an XML structure for integration purposes, such as converting it to JSON within a SAP integration process. However, you face a compilation error when declaring and using an accumulator in your XSLT stylesheet. Here’s a quick look at the XML and relevant XSLT causing the issues:

The error message you received highlighted the fact that there were issues during stylesheet compilation, causing it not to function as expected.

The Solution

To resolve this compilation error, it's important to ensure that the appropriate schema namespace for the xs (XML Schema) prefix is declared. This is essential for the proper interpretation of the xs:integer type in your XSLT code.

Step-by-Step Guide

Here’s how to correct the issue:

Add the Schema Namespace: Modify your XSLT to include the xs namespace. You can either add it directly in the xsl:accumulator tag or include it at the xsl:stylesheet level. Here’s how to add it above the xsl:stylesheet element:

Conclusion

Following the steps outlined above should mitigate the compilation errors you're encountering with your XSLT stylesheet. Declaring the appropriate namespaces is crucial for successful compilation and execution of your XSLT transformations. By ensuring these declarations are included, you can move forward with transforming your XML data to JSON in SAP integration processes without further complications.

If you continue to face issues, consider validating your XML and XSLT with other tools, or consulting further resources for clarification on XSLT 3.0 standards.

Happy transforming!
