Re: [xslt] Structural difference between html and xml output?

Hi Daniel,

any comment on that problem?

The effect seems to come from either the saveEndTag-Column in the 
html40ElementTable (HTMLparser.c line 358 f), where li and p get a 1 
instead of 0 as other non-empty element or it's usage in HTMLtree.c (lines
541 and 1043) where end tags are omitted, if saveEndTag != 0 for this
element.
So it might be easily fixed by either changing the entries in html40ElementTable
to 0 or changing the test to `saveEndTag == 2'...

greetings
