What's New in Oxygen XML Webhelp 25.0

October 13, 2022

Oxygen XML WebHelp version 25.0 is the latest major release for the modern XML publishing system that is used to produce stylish WebHelp output from DITA or DocBook source content. Some of the most interesting enhancements added in this version include the ability to generate Google Structured Data in the output and to control the search support. New transformation parameters were added to specify a custom search engine, to change the default search engine, or to replace the main page with your own custom page. Customization possibilities were added for displaying a custom title in the search results page or for implementing your own custom search filter.

Core

Generate Google Structured Data

You can now generate Google Structured Data in DITA WebHelp Responsive output. Google uses structured data to better understand the contents of the page and display special search results in a Google Search. For details about how to do this, see How to Generate Google Structured Data.

Display Custom Title in Search Results

It is possible to display a custom title for topics in the search results page. This can be achieved by adding the <searchtitle> element inside the particular DITA topic (or inside the topic reference within a DITA map). The <searchtitle> element is used to specify the title that is displayed by the search tools that locate the topic. For more details, see How to Display Custom Title in Search Results.

Scaling in Image Maps Improved

Scaling when working with image maps was improved. Adding the @scale attribute on the <imagemap> element now scales both the image and its areas, if defined.

Replace Main Page With Your Own Custom Page

A new transformation parameter (webhelp.skip.main.page.generation) can have its value set to true to instruct the transformation engine to skip the default main page generation. This is helpful if you want to replace the default main page with a topic page or any other custom page.

Search Engine

Implement Your Own Custom Search Filter

It is possible to implement a custom search filter by referencing a custom JavaScript file in an Oxygen Publishing Template. For details on how to do this, see How to Implement a Custom Search Filter.

Search Expressions are Preserved in Search Filter

The search expressions that you type in the search filter field are now preserved after you click on a search result. This makes it more efficient to refine searches since you can edit or add text to the preserved search expression instead of starting over.

Use a Custom Search Engine

A new transformation parameter (webhelp.fragment.custom.search.engine.script) can be used to specify the path to an XHTML file that contains scripts required for a custom search engine that would replace WebHelp's built-in search engine. For more details, see How to Configure a Custom Search Engine.

Change Default Operator for the Search Engine

A new transformation parameter (webhelp.search.default.operator) makes it possible to change the default operator for the search engine. If the value is set to and, multiple word queries result in the search engine only returning results for topics that contain ALL words. If the value is set to or (default value), multiple word queries result in the search engine returning results for topics that contain ANY of the words.
