Hi
First, I am quite a newbie at submitting feedback to an apache
project, so I am not sure if I chose the right place, but I haven't
found how to create an account in the JIRA issue tracker.
I am using Doxia as a stand alone library in my application to
generate PDF files using a source written in Markdown, with markdown
and FO modules, and Apache Fop. I don't know if this a frequent use
case, but I found some issues:
- First, I encountered this issue:
http://jira.codehaus.org/browse/DOXIA-480 (html entities ignored by
the xhtml parser) , but the consequence were more dramatic in my case:
The AbstractXMLParser.handleEntity(parser,sink) create a null String
and give it to sink.text(), causing a nullPointerException in
FoSink.escaped(String,boolean) (line 1600).
Exception in thread "main" java.lang.NullPointerException
at org.apache.maven.doxia.module.fo.FoSink.escaped(FoSink.java:1600)
at org.apache.maven.doxia.module.fo.FoSink.content(FoSink.java:1588)
at org.apache.maven.doxia.module.fo.FoSink.text(FoSink.java:1315)

org.apache.maven.doxia.parser.XhtmlBaseParser.parse(XhtmlBaseParser.java:90)
at
org.apache.maven.doxia.module.markdown.MarkdownParser.parse(MarkdownParser.java:71)
The correction of DOXIA-480 bug corrected this problem, but I think a
null-check in FoSink.text or FoSink.escaped would be useful.
- A second issue: Is there any reason the <h1> tag is ignored by
the xhtml parser?
I fix this by using the title() method, since my markdown document
doesn't have <head>.
- A more annoying problem: The FoSink class produce invalid XSL-FO
document: more precisely, the fo:flow and fo:page-sequence are ended,
by the body_() end method, but the body() start method does not open
them. There is a startPageSequence() protected function, but it is not
called in the FOSink class, even if it called in the FPAggregateSink
subclasse.
I can provide my patch to fix these issues if necessary, and I
attached an example using the Markdown parser, Fo Sink and Fop
demonstrating these issues (the first with Doxia 1.3, the others using
latest Doxia source).
Best regards
