[l2h] lowercase_tags does attributes imperfectly

Fri, 15 Nov 2002 20:47:48 -0500

The regular expression in &lowercase_tags doesn't handle multi-word
attribute values nor the attribute following a minimized attribute.
For example, it turns this:

<link rel="ToC" title="Lessons Table of Contents." href="./" ONE TWO>

into this:

<link rel="ToC" title="Lessons table of Contents." href="./" one TWO>

Notice that the word "Table" has been incorrectly lowercased, while
TWO has failed to be lowercased.


The following diff against v2002-2-1 (1.70) corrects this problem.

Running lowercase_tags over the document is a bit of a kludge; the
output should be lowercase tags by default.  This diff takes another
(small) step in that direction by changing some of the tags (mostly in
the head) to lowercase.

Finally, this diff puts quotes around a table attribute that was missing
them.
