Description

This class subclasses Text::WordDiff::Base to provide a XHTML formatting for Text::WordDiff. See Term::WordDiff for usage details. This class should never be used directly.

Text::WordDiff::HTML formats word diffs for viewing in a Web browser. The diff content is highlighted as follows:

•: "<div class="file">"
This element contains the entire contents of the diff "file" returned by "word_diff()". All of the following elements are subsumed by this one.

"<span class="fileheader">"
The header section for the files being "diff"ed, usually something like:
```
  --- in.txt    Thu Sep  1 12:51:03 2005
  +++ out.txt   Thu Sep  1 12:52:12 2005
    
```
This element immediately follows the opening "file" "<div>" element, but will not be present if Text::WordDif cannot deterimine the file names for both files being compared.
"<span class="hunk">"
This element contains a single diff "hunk". Each hunk may contain the following elements:

"<ins>"
Inserted content.
"<del>"
Deleted content.

You may do whatever you like with these elements and classes; I highly recommend that you style them using CSS. You'll find an example CSS file in the eg directory in the Text-WordDiff distribution.
