Running the Diff Tool from the Command Line

In addition to using the Diff tool from the Stylus Studio user interface, Stylus Studio also provides a commandl line utility, StylusDiff.exe. This command line utility allows you to perform many of the same functions, and to use many of the same options, as the graphical Diff tool.

Restrictions

The following restrictions exist for using StylusDiff.exe:

  • You cannot use StylusDiff.exe to diff folders
  • StylusDiff.exe can diff only one pair of documents at a time

Usage

The StylusDiff.exe utility has the following usage:

StylusDiff -source <sourceURI> -target <targetURI>
[-expandPrefixes/collapsePrefixes] [-expandERs/collapseERs]
[-comments/nocomments] [-attributes/noattributes] [-text/notext] [-pi/nopi]
[-er/noer] [-entities/noentities] [-formatting/noformatting] [-fold/nofold]
[-auto/best/fast]

Table 19 describes the usage for the StylusDiff command. For a complete description of these and other options that affect the XML Diff engine, see Engine Settings.
