XHTMLSerializer uses entity references " and ' which cause JavaScript
parse errors
--------------------------------------------------------------------------------------------
Key: COCOON-2249
URL: https://issues.apache.org/jira/browse/COCOON-2249
Project: Cocoon
Issue Type: Improvement
Components: Blocks: Serializers
Affects Versions: 2.1.12-dev (Current SVN), 2.2-dev (Current SVN)
Reporter: Andreas Hartmann
The XHTMLSerializer, or, more specifically, the XHMLEncoder, from the
serializers block in Cocoon 2.1.x escapes all characters with a corresponding
HTML 4.0 character entity reference into this entity reference. This causes
issues with inline JavaScript, since e.g. the double quotes are transformed to
" which causes a JavaScript parsing error. Another minor negative effect
is the increased document size.
If I understand the W3C correctly, see e.g. [2], the recommended approach is to
use the character set of the encoding as far as possible,
and use escapes only in exceptional circumstances. I didn't find a reason why
the XHTMLSerializer uses escapes, but I suspect that it is related to browser
compatibility issues.
Maybe we could make this behaviour configurable, e.g.
<use-entity-references>true|false</use-entity-references>
