UPDATE: I solved the problem. Convert with html tidy. See my comments below if you want a script out of the box... ******************

Monks, I have a question about keeping quotes in Treebuilder-parsed html.

HTML::Treebuilder strips quotes around numerical attributes, as can be seen in the example below, which includes the test I want passed.

According to the client I've got, without quotes around all attributes, we have valid html but not xhtml. One workaround is changing the behavior of HTML::Treebuilder, or perhaps the as_html method of HTML::Element. Another would be an html to xhtml converter, if anyone can recommend one.

I appreciate any leads for solving this. 

use strict;
use warnings;
use HTML::Treebuilder;
use HTML::Element;
use Test::More qw(no_plan);

my $html=
'<table>
    <tr>
        <td valign="top" width="10"></td>
    </tr>
</table>';

my $treeroot = HTML::TreeBuilder->new;
my $html_tree = $treeroot->parse( $html);

print $html_tree->as_HTML();

#the quotes around 10 get stripped away.
#(the quotes around top are kept.)
my $wanted = q{<html><head></head><body><table><tr><td valign="top" wi
+dth="10"></td></tr></table></body></html>};
my $got = $html_tree->as_HTML();
is($got, $wanted);

********************* UPDATE: script to do this with tidy, quoting from the how-to linked to above. 
my (@files, @rippers);
@files = Filecontrol::get_files($dir);

foreach my $file (@files) {
    `tidy -asxml -m  $file`;
}

"The spaces are important and so is every consonant. What does all that code mean? First, tidy identifies the program to use. -asxml instructs Tidy to convert the HTML document to XHTML. -m tells the program to modify the document in its current location, and c:\XHTML\tidy.htm is the location of the messy document to be converted."
