XyDiff Tools
Detecting changes in XML Documents
XyDiff is a free set of tools developped by the GEMO team at INRIA-Rocquencourt, near Paris.
The object of the program is to detect changes on XML documents.
Thus, the main usage for it is versionning, as well as dynamic notification
of changes.
XyDiff has been designed from the begining to XML data. It uses a novel Change Model tailored to XML data.
AUTHORS
XyDiff has been developped at INRIA, a well-known CS research lab in France. In was developped in the context of the Xyleme project which aimed at creating a large warehouse of XML data and documents. The technologie used in XyDiff has been published in international research conferences:- Change-Centric Management of Versions in an XML Warehouse,

A Java version of XyDiff is used to synchronize XML documents, in particular OpenOffice documents. The Java port has been achieved by Raphael Tani supervised by Pascal Molli. |
DESCRIPTION
XyDiff version 2.0 and after contain following tools:
- XyDiff: A program which compares two versions of an XML file and create a 'delta' that describes all changes that occured between the first version and the second version of the document.
- XyDeltaApply: A program which applies a 'delta' on some document version in order to reconstruct the other version of the document.
- XyCmp is a tool to compare two XML documents and decide whether there are identical or not.
- XyDebugXid is a debug tool which displays the persistent identifiers that are assigned to nodes when storing versions.
- XyReverse is a tool which reverses the delta, i.e. given a delta transforming document version 1 into version 2, it constructs the delta which transforms version 2 into version 1.
- All the functions previously described (and more) are available using C/C++ interfaces.
- Autotest: An autotest program and scripts which checks on sample data the correct execution of the XML diff/restore/compare functions.
- XyLoad/XyRetrieve: (post-poned to V3.0) This program allows to sequentially store versions of some documents in a version repository. The version repository consists of an aggregate delta for each document that contains the delta for all versions of that documents. When versions are loaded using XyLoad, the 'delta' is extended. Using XyRetrieve, it is possible to recover any past version of the document.
FEATURES
-Extremely fast algorithm, supports very large files (10+ Mb)-Tools to compute the delta between two XML files, reverse the delta, apply the delta on a file, ...
-Xerces/DOM based structures and library to manage simple XML documents, their versions and persistant identifiers
-Package includes self-test program
-Option to ignore whitespaces and formatting characters in XML files
