Subject: close tag missing from optionally empty XML tags
Download (untitled) / with headers
text/plain 403b
When you add a tag to empty_element_map and it optionally contains text or other content, when the content is present the opening tag correctly has '<foo>' instead of '<foo/>', however the closing tag is missing from the text returned by as_XML. This is due to traverse not correctly validating tags as empty in the check for setting callbacks. Attached is a patch which fixes this bug. Cheers, Jeff.
