For all I know the serializer does not actually output anything directly. It
hands over the task to the transformerhandler and this is where the culprit
resides.
There is no need to extend the current serializer if I adapt the current way
of working.
XmlSerializer, Html4Serializer and XhtmlSerializer are all just XmlSerializers
with a different set of properties and the current XMLSerializer class
provides static methods to create them. It makes much more sense to add a
static factory method for a html5 serializer there as well.
The problem is that currently to actually have the transformerhandler output a
doctype declaration you do need to pass I think a doctypepublic property but
this cannot be empty from the looks of it:
public XMLSerializer setDoctypePublic(String doctypePublic) {
if (doctypePublic == null || EMPTY.equals(doctypePublic)) {
throw new SetupException("A doctype-public has to be passed as
argument.");
}
this.format.put(OutputKeys.DOCTYPE_PUBLIC, doctypePublic);
return this;
}
public XMLSerializer setDoctypeSystem(String doctypeSystem) {
if (doctypeSystem == null || EMPTY.equals(doctypeSystem)) {
throw new SetupException("A doctype-system has to be passed as
argument.");
}
this.format.put(OutputKeys.DOCTYPE_SYSTEM, doctypeSystem);
return this;
}

Ok, then create an HTML5Serializer that extends the current Serializer. An
other solution would be to add a boolean that will output differently for html5
but I'd prefer extension above a number of if statements.

And in my mail I was actually referring to C3. You are right about what you
write but I'd prefer to have a Serializer which follows the spec so I can just
copy the output and validate it without errors and too many warnings at
http://validator.w3.org/

Subject: Re: HTML5 serializer
Hey Robby,
which Cocoon version are you using for your project? In C2.1 and C2.2 there's
not only a XMLSerializer but also an HTMLSerializer and XHTMLSerializer for
their specific needs. So why not create your own HTML5Serializer?
In HTML5 the specification teams tried to specify what browsers were already
doing instead of making a new theoretical specification. HTML5 should be
backwards compatible with previous (X)HTML versions. This is the reason why
some old elements are not deprecated but considered obsolete (remember marquee,
it was so cool on Geocities).
The doctype doesn't really matter, browsers generally ignore the PUBLIC part in
the doctype (apart from some hacks in IE going into quirks mode).
A good presentation about HTML5 is http://vimeo.com/15755349.

Hi all,
I've been looking at how to add a HTML5 serializer to the project.
So far my investigations have led to add following code to
org.apache.cocoon.sax.component.XMLSerializer
public static XMLSerializer createHTML5Serializer() {
XMLSerializer serializer = new XMLSerializer();
serializer.setContentType(TEXT_HTML_UTF_8);
serializer.setDoctypePublic("XSLT-compat");
serializer.setEncoding(UTF_8);
serializer.setMethod(HTML);
return serializer;
}
Using the HTML5 serializer in a test to print the output:
@Test
public void testHTML5Serializer() throws Exception {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
newNonCachingPipeline()
.setStarter(
new XMLGenerator("<html><head><title>serializer
test</title></head><body><p>test</p></body></html>")
)
.setFinisher(XMLSerializer.createHTML5Serializer())
.withEmptyConfiguration()
.setup(baos)
.execute();
String data = new String(baos.toByteArray());
System.out.println(data);
}
Would print
<!DOCTYPE html PUBLIC "XSLT-compat">
<html>
<head>
<META http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>serializer test</title>
</head>
<body>
<p>test</p>
</body>
</html>
I read a number of articles describing the issues with serializing html5 and so
far this was the best I could come up with which is not 100% conforming due to
* Non matching doctype although it will not break in the browser -->
should be <!DOCTYPE html>
* The charset should be <meta charset="UTF-8"/> according to html5 spec

Does anyone have more knowledge on this subject?
