Merging XML Files Using SAXON and XSLT: A Simple Guide

Are you overwhelmed with a collection of XML files that you need to merge into one? If you're new to XSLT and SAXON, merging these files may seem daunting. But it doesn't have to be! In this guide, we'll walk you through the process of merging multiple XML files into a single file using SAXON and XSLT. By the end, you'll have a clearer understanding of how to handle XML files efficiently.

Understanding the Problem

Let's start by discussing the data structure you're dealing with. You have several XML files that represent a benchmark, and each of these files contains elements structured as follows:

Your goal is simple: merge all these <xpath> elements and their children into a single XML document with one root <benchmark> node. Let’s dive into how you can achieve this goal using XSLT and SAXON.

Step-by-Step Solution

1. Create the XSLT Template

The first step is to create an XSLT template that will perform the merging of the XML files. You can start with a named template, which will not need any input XML. Instead, it will pull in all the data from the directory using the collection function. Here's what your XSLT should look like:

Explanation

<xsl:template name="main">: This defines a template named "main" that you will call later.

<benchmark>: This creates a new root element for your merged XML file.

<xsl:copy-of select="collection(...">: This line collects all XML files in the specified directory, ensuring that each <xpath> node (along with its children) is included into the merged file.

2. Running the SAXON Command

Once you have your XSLT file ready, the next step is to execute it using SAXON. You can run the following command in your command line interface:

Breaking Down the Command

-xsl:mergefiles.xsl: This specifies the XSLT file you created.

-it:main: This tells SAXON to invoke the "main" template you defined.

-o:merged-file.xml: This specifies the name of the output file where all merged contents will be stored.

Conclusion

Merging XML files can be efficiently handled with SAXON and XSLT, using the methodology we've outlined in this guide. By leveraging the power of XSLT templates and SAXON’s command line capabilities, you can quickly combine multiple XML files into a single document with ease.

If you follow these steps, you’ll find that working with XML data becomes a lot more manageable. Whether you're compiling benchmark data or processing other types of XML files, this approach will save you time and effort. Happy merging!
