xslt-dependency-graph calculates the dependencies of a set of XSLT 2.0 stylesheets. (A stylesheet depends on another when it imports or includes that other stylesheet.)
A DOT-language graph is produced, representing the stylesheets and their dependencies. This graph can be given to one of the graph layout programs of the Graphviz suite to visualize the dependency structure of a project with multiple XSLT stylesheets.
An XSLT 2.0 processor.
This tool was designed with XSLT 2.0 stylesheets in mind. It might not work on stylesheets written in earlier versions of XSLT. It's a hack, so it probably misses some corner cases.
An accompanying shell script is included to drive an XSLT 2.0
processor, providing a somewhat reasonable command-line
interface. The Saxon-B processor is assumed to be installed,
available with the command-line tool
(as it is under Debian). The script could be easily adapted to
other scripting languages—for non-Unix platforms—or
to use another XSLT 2.0 processor.
./depgraph STYLESHEET [STYLESHEET ...]
Each named stylesheet will be loaded and its dependencies traversed. The resulting DOT graph, which is printed on standard output, will include each named stylesheet, as well as any stylesheets that they ultimately depend on.
Pipe the output to
dot or one of the other
Graphviz programs to generate an image representing the
./depgraph STYLESHEET [STYLESHEET ...] | dot -Tpng > dep-graph.png
For best visual results, it helps if all the stylesheets are in
the same directory, or closely spaced together under different
subdirectories of the same directory. If this doesn't fit your
project, you can customize how nodes are labelled within
The most recent release is 0.1, released 2009-09-11. It has no external dependencies.
