Altova announced that a new dedicated differencing utility has been added to its product line. Altova DiffDog 2005 is a synchronization tool that facilitates the comparison and merging of files, folders, and directories for application developers and power users. DiffDog 2005 is available in both Standard and Professional editions. DiffDog 2005 Standard and Professional editions allow users to quickly compare source code files, HTML files, or any text-based files then merge changes with a click of the mouse. Both editions deliver comparison and merging options for all file directories as well. DiffDog 2005 Professional Edition also provides advanced XML-aware differencing and editing capabilities based on those popularized in Altova XMLSpy. DiffDog 2005 integrates with any version control system that supports external differencing applications. Intelligent syntax-coloring, line numbering, indentation guides, folding margins, and other innovative features are provided to assist in comparing source code and XML files. Special XML differencing capabilities in DiffDog 2005 Professional Edition include DTD/schema-based validation, well-formedness checking, intelligent entry helpers, optional entity resolution, and attention to attribute and child element ordering. Developers can compare XML files in either an advanced text view or enhanced grid view. Altova DiffDog 2005 is immediately available for purchase in both Standard and Professional Editions with (USD) prices for a single-user license starting at $69 and $129 respectively.
