New Features 2026
Version 2026r2
•Artificial Intelligence (AI) support in XMLSpy has been introduced for specific XML tasks such as generating, from an XML schema, a sample XML file that contains realistic XML data. Other specific tasks include creating XSLT and XQuery documents on the basis of source and target XML files. This functionality is described in the topic Altova AI (for Specific XML Tasks).
•All the AI functionality of XMLSpy can now be accessed from a single location, the AI Guide window, which also provides access to more broad-based chats from within the XMLSpy user interface.
•From v2026r2 onwards, Altova has changed its taxonomy management system to use taxonomy packages rather than taxonomies. This is mainly because most authorities now issue packages. In the XMLSpy interface, the new Taxonomy Package Manager works in the same way as the previous XBRL Taxonomy Manager.
•Database support has been extended to PostgreSQL 18.
•Eclipse support has been updated to cover the following versions: 2026-03 (4.39), 2025-12 (4.38), 2025-09 (4.37), 2025-06 (4.36).
Version 2026
•BSON data files can be edited in Grid View with editing features such as type support, entry helpers, and validation against a JSON schema for BSON. The various XMLSpy features for BSON files are described in the section BSON.
•BSON files can be converted to and from JSON or YAML files.
•For XSLT 3.0 transformations, assertions can be enabled via an application-wide setting.
•The menu command XBRL | New Taxonomy enables you to create an XBRL taxonomy either as a taxonomy package or as a collection of taxonomy files.
•In the Package Settings tab of the Options dialog, you can set the default way to open XBRL taxonomy packages: (i) open the entry point taxonomy schema in XBRL View or (ii) open the taxonomy archive in Archive View.
•The command XBRL | Package Metadata opens the metadata file of the active XBRL taxonomy package. There is also an option to always open the metadata file after a new taxonomy package has been created.
•Commands to import XBRL taxonomies and reference linkbases have been reorganized in the XBRL menu and the Overview entry helper of XBRL View.
•Taxonomy Manager has an option to set whether to store taxonomies in the ProgramData folder or the user's Documents folder. This is useful if you do not have permissions to write in the ProgramData folder.
•An option to additionally check xBRL-CSV Table Constraints during validation of xBRL-CSV reports has been introduced.
•For conversions of xBRL-XML reports to other OIM formats (CSV or JSON), you can specify that tuple-based filing indicators are converted to dimension-based filing indicators.
•Database support has been extended to MariaDB 11.8 (LTS), MySQL 9.1, PostgreSQL 17.
•Eclipse support has been updated to cover the following versions: 2026-03 (4.39), 2025-12 (4.38), 2025-09 (4.37), 2025-06 (4.36).
