Configure to find the changes you need to know about
DeltaXML’s algorithms work through each of your files in turn, examining their structure to match-up all the corresponding elements with the original.
XML Compare identifies all of the differences in your content according to your specific configuration. It then writes them to an output file which combines your original content with new markup detailing the changes.
You decide which changes to keep
Display the changes from XML Compare or XML Merge in an XML editor to manually accept or reject changes. Or apply custom rules to automatically determine whether to accept the changes or mark them up in the output file as unresolved changes.
Show the difference in a way that makes sense to you
The results are passed through a pipeline so you can transform the XML into whatever form is required by your systems or processes. This is all managed through DeltaXML’s API.
Compare and merge your own XML files

Text formatting intelligence
In XML, text formatting uses structural markup like em or strong to add styling to text content. DeltaXML handles this markup with specific processing so that you have a clear understanding of where text remains unchanged despite formatting changes. Even where text remains the same, our compare and merge delta format shows you how formatting changed between versions.
Compare CALS and HTML tables with ease
XML tables are complex enough without having to worry about how to compare and merge them. We process CALS and HTML tables to make sure that the results are valid against the table models while still delivering accurate comparisons and merging.
Change highlighting MathML comparisons
MathML handling is built into XML Compare’s ‘Document Comparator’. When MathML content inside your documents is compared, change highlighting is created using MathML syntax to add coloring and styling to your MathML. Three different output styles allow you to choose the one that best suits your publication.
Find the change that matters to you, ignore the diffs that don’t
Comparison results can be configured to show in any form you need, whether for automated processing or human review.
Automatic or manual change resolution
When the aim of a merge is to reach a new version of a document, you’re often only interested in reviewing the conflicting changes. XML Merge allows you to automatically ‘accept’ changes that don’t conflict, only marking up those that are in conflict. This reduces the time needed to review the result. Of course if you do want to review all differences between the documents, including those which don’t conflict, that’s still possible. In fact you can determine which changes should be included in the result using our rule-based processing feature.
Smart comparison of XML documents
Sometimes you don’t need to see every tiny change, especially for content that you know will change, like dates and timestamps. That’s why we offer samples showing you how to configure XML Compare to ignore these insignificant changes. All you need is a custom XSLT transformation plus a couple more that we’ve already written for you.
An easily processable delta format
Whether you choose to include all changes or just those that conflict across versions, the changes are output in our simple XML-based delta format for easy processing. Designed to be easily transformed using XSLT, our delta format sits lightly within the original XML content to ensure that your results are as close as possible to the original XML format.

Frequently Asked Questions
What is the DeltaXML package?
DeltaXML is a package consisting of the toolkits XML Compare and XML Merge. While XML Compare finds all of the meaningful changes between any two XML files, XML Merge recombines multiple XML documents or datasets into a single file.
How do I integrate or embed the DeltaXML package?
Both XML Compare and XML Merge are optimised for integration into any enterprise workflow and content management systems. All of their functionality is accessed through Java or REST APIs, which are fully documented and come with complete, working examples. On top of these API’s we have created plugins for popular XML authoring tools, including oXygen and FrameMaker for seamless content authoring and reviewing.
Can I ignore changes I know about?
Yes. DeltaXML can be configured to tell you about the differences that matter to you and ignore those that don’t, including changes to attributes, the order of content, differences in whitespace and external links.
If you are working with documents or textual content, you have fine control over differences between words, sentences and whole blocks of text. XML Compare also allows you to specify how formatting changes are reported, while XML Merge can apply custom rules to specify what is merged automatically and what is marked-up for further attention.
How is DeltaXML different from other diff tools?
Rather than comparing XML line-by-line, DeltaXML identifies and matches up all the XML elements across your files, so it has a meaningful and dependable basis for comparing and merging your content.
This pairing process uses a combination of element names, parent names, position in the XML tree and the structure of child elements. It understands namespaces and prefixes and can be configured to use keys to guide alignment of content.
How are found differences represented?
DeltaXML generates output files that are structured in the same way as your original files, so they can be viewed in your regular editor or managed in your CMS. With XML Merge an output file which is based closely on your original ancestor file will be generated, with all unresolved changes laid-out using precise, descriptive XML markup.
The real power comes from its use of XSLT pipelines, which enable you to apply transformations and generate the exact output that you require, for internal workflow, wider distribution or in your product code.
