XML Diff and Merge
The complete XML diff and merge solution offers
directory, file, and XML fragment comparison, six different algorithms and multiple levels
oXygen XML Diff and Merge Tools
In large teams composed either of developers or technical writers, the use of a shared
repository for the source or document files is a must. Often many authors are changing the
same file at the same time.
Finding what has been modified in your files and folders can be hard. If your data is
changing, you can benefit from accurate identification and processing of changes in your
files and folders with the oXygen comparison tools for comparing files and comparing
These are powerful and easy-to-use tools that will do the job fast and thoroughly.
With the possibilities of comparison and merging, it is easy to manage multiple
Compare Files Tool
The comparison of a pair of files is done by opening them in two
editors arranged in a side by side layout. You can edit both the source and the target
file and the differences are refreshed when you save the modified documents. You can
also compare XML fragments, without selecting files, by copying and pasting them into
either side of the comparison tool. While comparing files or fragments you can merge
differences by using the toolbar buttons or actions from the contextual menu. File
comparison and merging actions can also be performed on files inside ZIP-based archives.
The differences are presented in a graphical format and scrolling
is synchronized so that the matches are kept close to one another. Guiding areas are
painted between the two files or fragments to allow you to easily locate the
corresponding differences. An overview ruler helps track the changes.
The comparison solution includes a variety of XML diff
algorithms. It includes an XML Accurate algorithm for precise compare,
a XML Fast algorithm for speed at the expense of some accuracy, and
three algorithms that rely on the file structure (line-based, word-based, and
character-based). It also includes a syntax-aware algorithm that provides comparison
results for all file types and XML fragments that are recognized by oXygen. Any
algorithm can be used to perform differences on request, but the oXygen Compare
Files tool also offers an automatic selection that chooses the most appropriate
algorithm based on the content and size of the files or fragments.
The XML diff algorithms are designed to help you with your specific needs for
comparing XML documents or fragments. This means that you can specify whether or not
namespaces, prefixes, namespace declarations, processing instructions, comments, CDATA,
DOCTYPE, the order of attributes, or even text elements should be ignored.
The comparison operations do not interfere with the user interface. They display
progress information and allow the user to cancel them at any time. The multiple levels
of comparison support allows you to go deeper into found differences and see what is
actually modified, and all of the multiple levels include full merging support.
Word Level Comparison
When there are modifications between the source and the target file or fragment,
you can see them in detail, at word level, by selecting the
Show Word Level details option from the Compare menu.
Character Level Comparison
You can also see modifications in even deeper detail, at character level, by
clicking the Show Character Level detail button from the Compare
Both the Compare Files and Compare Directories tools are available as stand-alone
applications and are also integrated into the oXygen Tools menu.
Compare Directories Tool
The directory comparison results are presented using a tree view.
The directories that contain different files are expanded automatically, allowing you to
focus directly on the differences. You can merge the content of the directories by using
the copy actions from the toolbar, or you can examine the content of the different
files. The comparison and merging actions can also be performed inside ZIP-based
archives (ZIP, JAR, ODF, OOXML).
When performing a comparison between directories/archives, the files can be compared
by using several methods:
- by timestamp - Only the file date and size are compared (fastest
method). This is useful when the directories contain a lot of different files.
- by content - The file content is compared using the default diff
algorithm. Depending on the selected algorithm, the appropriate options will be
considered (such as ignoring the white-spaces, ignoring the namespace prefixes,
- binary comparison - The file content is compared byte with byte.
This is faster than the by content method, but should especially be
used for differences of importance.
Filters are included to help specify the set of files that will be used during the
comparison operation. For example, you can choose to see only the differences from XML
or XSL file types. By default, the comparison is made on all file types.
If a file or a folder exists only on one side of the compared directories, the name
of the file or folder will be colored blue and marked with an "X". If a file exists in
both directories but the content is different, the name of the file will be colored red
and marked with a "not-equal" sign.
By double-click on a line containing image files, a Compare Images dialog will be
displayed. The dialog displays the images in both sides, scaled to fit the available
area in the view. You can use contextual menu actions to scale the images to fit in
the view. This is useful for visual comparison.
The supported image types are: GIF, JPG / JPEG, PNG, BMP.
