DocBook Compare’s algorithms allow you to compare two DocBook documents, analysing their content and structure and matching all the corresponding elements between them to accurately identify and represent changes in your documents.
DocBook Compare’s configurability allows you to focus on changes important to you, and then represent them in DocBook markup. This representation combines your original content with the new markup making it possible to see the individual changes in your content.
If you’re wanting to try out DocBook Compare’s powerful performance, try our online demo which offers fundamental functionality; diff two of your own DocBook files and compare the changes. If you’d like to see all DocBook Compare has to offer book a one-to-one demo with a DeltaXML developer.
There’s no need to change your existing DocBook publication workflows for DocBook Compare. The comparison process is tailored specifically for DocBook content producing valid DocBook output, where changes are marked using native DocBook markup. Elements are marked with the @revisionflag attribute and text changes are wrapped in elements to enable the change markup to be applied at the word level.
DocBook Compare handles structural markup like
and semantic inline markup like
with specific processing so that the focus is on content change without any adverse effects from formatting. The list of elements to handle is fully configurable, allowing you to add or remove elements from our predefined list or replace the whole list with your own.
MathML handling is built into DocBook Compare as standard. 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.
Comparison results can be configured to show in any form you need, whether for automated processing or human review.
XML tables are complex enough without having to worry about how to compare them. We process CALS and HTML tables to make sure that the results are valid against the table models while still delivering accurate comparisons.
When editing documents it’s commonplace to move chunks of content from one location to another. In these circumstances, it can be useful to understand that this was a move operation rather than a deletion and an addition. DocBook Compare uses element ids to identify this type of change and mark it as a move so that you have the option to style it differently if needed.
Understanding when externally referenced content changes is just as important as understanding text changes within a document. DocBook Compare can identify when a referenced image has changed but can also identify when a modified href actually points to the same image.
When you publish documents, like standards, that are relied on as a key part of your customers’ work it can be difficult for them to manage the transition to an updated version. Many customers, including standards bodies (international, national and industry-specific), use DeltaXML’s products to drive a redline document workflow. DocBook Compare identifies the changes between publication versions, marks them in the source XML and the resulting output feeds into the usual publication workflow where styling is added to changed content to help your customers to understand exactly what updates appear in this latest revision.
Reviewing document updates can be an onerous task, particularly when the documents are large. The task becomes much easier if you can see exactly what has changed since the last time the document was reviewed. DocBook Compare identifies changes between two specific revisions, allowing you to produce a version specifically for reviewers that highlights the precise changes that you want them to review. Because it operates on the source XML there is no need for change tracking and you have the flexibility to edit and review on different platforms. If your reviewer is familiar with XML editors, DocBook Compare can even generate PIs to show the changes it identified as if they were track changes in a range of popular tools.
What is DocBook Compare?
DocBook Compare is a complete toolkit for reliable DocBook comparison. It is the most efficient and dependable way of identifying all the changes within your DocBook content.
How do I integrate or embed DocBook Compare?
DocBook Compare is optimised for integration into enterprise workflow and content management systems. All of its functionality is accessed through its Java 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. DocBook Compare 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.
How is DocBook Compare different from other diff tools?
Rather than comparing line-by-line, DocBook Compare identifies and matches up all the elements across your DocBook content, so it has a meaningful and dependable basis for its comparisons.
This pairing process uses a combination of element names, parent names, position in the XML tree and the structure of child elements.
How are found differences represented?
DocBook Compare has been designed to make all your content changes easy to work with. It generates well-formed, valid DocBook content so the resulting output is compatible with your existing DocBook tools. Where this involves tables, a sophisticated process works out the best way of showing all the changes, while still generating a valid table.
