HTML Diff Script

This is a first cut at a script to compare HTML specifications. Usage is simply:

htmldiff file1.html file2.html > diff.html

The script does not copy any CSS and images required by the input specs, so it's best to generate the output in the same directory as one of the inputs.

The scripts used require Python and Perl. Additionally, the python 'utidylib' module and the underlying libtidy C library are required, which may make it challenging to run the scripts on non-Linux platforms. It is not known if these requirements can easily be removed.

Usage Notes

• For Debian/Ubuntu distros, install the python-utidylib package, which should also install the libtidy packages.
• The directory containing the htmldiff.pl Perl script needs to be in the PATH.

The scripts are taken from the code backing the

http://services.w3.org/htmldiff

website.

Files

• htmldiff is the Python driver script.
• htmldiff.pl is the Perl script which generates the diff after preprocessing of the input HTML by htmldiff.
• htmldiff.orig is the original Python script from the website as a CGI script. This script was modified to run at the command line and saved as htmldiff.
