What is DiffX?
DiffX is an open source Java API for comparing XML documents
by analyzing the sequence of XML events.
A common requirement when processing XML data is to compare
one version of a file to another. When doing this, it is often
more interesting to know that a word in the text of chapter
X, paragraph Y has been changed rather than knowing that line
Z is different. In addition, there are a number of changes
such as the order of the attributes, different white space
for indentation or namespace prefixes that may not hold much
interest. The problem with many comparison tools is that they
report either too much information or not the most important
information.
It is also difficult to find good software with a forgiving
license!
Why Bother?
Basically we needed a Diff for XML API and we couldn't find
anything that fit our needs so we wrote our own. While we
think that our code is useful and we fully intend to continue
development, we have not set out to create a commercial product.
If you need real industrial strength diffing, go see the good
people at DeltaXML.
If you like our software and you are so inclined we will
gratefully accept PayPal donations. You might also be interested
