-------------------------------------
Summary: XhtmlBaseParser ignores XHTML default entities
Key: DOXIA-480
URL: https://jira.codehaus.org/browse/DOXIA-480
Project: Maven Doxia
Issue Type: Bug
Components: Core, Module - Xhtml
Affects Versions: 1.4
Reporter: Andrius Velykis
Attachments: doxia-core-XhtmlBaseParser.patch,
doxia-xhtml-entities-bug.zip
XHTML defines a number of default entities that can appear in valid XHTML files
(http://www.w3.org/TR/xhtml1/#h-A2), such as left/right quotes: “,
’, and many others.
XhtmlBaseParser, however, ignores XHTML default entities appearing in the
source code. This is because it delegates the parsing to AbstractXmlParser,
which uses vanilla MXParser to parse. MXParser only recognises default XML
entities.
Because the HTML entities are not resolved by the XML parser, and thus by the
XHTML parser, they are not rendered by the XHTML module. I have attached a
sample project for Maven site that uses XHTML module. The source file has
double/single quotes, however the output file does not.
This also affects other parsers that extend XhtmlParser, e.g. MarkdownParser
(see DOXIA-473 for a reported bug). This is because Pegdown library, used to
parse Markdown, generates “ for quotes and other entities.
I have attached a patch that fixes this problem. It exposes the XmlPullParser
(MXParser) for configuration before parsing, so that extending classes could
define default entities. Then XhtmlBaseParser adds default XHTML entities to
the parser. This patch will also fix DOXIA-473, because MarkdownParser extends
XhtmlParser.
