Ignore DTD option

jkarretero — Wed, 15 Apr 2009 14:49:09 -0000

It would be useful to add an "ignore DTD option" to the command-line parameters.

Sometimes people don't need the DTD file for a transformation and would like to ignore it.

For example, if doctype reffers to an online DTD file, you must be connected to internet to be able to process the xml, although you don't need the DTD.

Microsoft MSXSL does have that option (-xe).

Thanks for your work!

On the fly Transform

yannick lamothe — Thu, 04 Sep 2008 08:56:33 -0000

Hi,

Joost is really interesting as it allows transformation of huge XML files without any issue. However, the use of the transform() method to trigger the transfom is really constraining when several actions need to be piped.

What would be interesting is to have a utility class as JoostOuputStream, which we can initialize by passing another outputStream.

JoostOutputStream jStream = new JoostOutputStream(
new StreamSource(stxFile),
new StreamResult(destinationStream)));

//Coupling with FTP for instance
ftp.retrieveFile(filename, jStream);

In this example, FTP will retrieve the file, in jstream, which will transform it on the fly and write the transformed stream to the destination. We can add more pipes such as PGP encoding or decoding (BouncyCastle is supporting this type of implementation), MD5 calculation (fast MD5 by twmactina is also support this approach), ...

Do you think this is something which is feasible (as I think Joost implmentation is based on Streaming techniques) ? If you need more elements, please feel free to contact me (yan at s2r dot fr).

Thanks

Provide processing of java.lang.Number values

Anonymous — Fri, 23 Dec 2005 00:27:37 -0000

In net.sf.joost.stx.Value#Value(Object) there is a long
list of if's determining whether a value is boolean, a
number, or some other kind of object. The tests for a
number check all of the usual subclasses of
java.lang.Number.

I propose adding a check for java.lang.Number, a la;

else if (obj instanceof Number) {
type = NUMBER;
number = ((Number)obj).doubleValue();
return;
}

Actually, all of the tests for instance of Byte, Short,
Integer, and Long could be replaced by this clause,
since the assignment 'number = ' results in a promotion
from the natural type to double anyway.

The purpose of this change would be to allow classes
derived from Number, such as
org.apache.commons.lang.mutable.*, to be processed as
numbers instead of objects, providing a performance
improvement in evaluations, as these types of objects
wouldn't have be run through the

return Double.parseDouble(getStringValue());

object processing in #getNumberValue(). Also allows
applications to use Mutable objects to avoid repeated
'new'ing of immutable counterparts.

Thanks for listening.

Add prefix mappings from inside a transformation

Maarten Koskamp — Tue, 25 Oct 2005 12:28:10 -0000

When creating output with mixed namespace, the
serializer does not contain prefix mapping for
namespaces that were not in the input, but were instead
introduced in the transformation. This leads to the use of
a lot of xmlns attributes in the output, creating an
unwanted increase in document size. Is it possible to
call startPrefixMapping and endPrefixMapping on the
serializer for prefixmappings that are present in the
stx:transform node and are not explicitely excluded?

A further enhancement would be to be able to add prefix
mappings on templates resulting in calls to
startPrefixMapping when entering the template and a
call to endPrefixMapping when exiting the template.

Use non-scientific notation for numbers

Maarten Koskamp — Tue, 25 Oct 2005 12:22:33 -0000

When using variables to sum numerica data, the result
is returned in scientific notation when totals grow too
large (e.g. 1.23E9).

This is a problem when the output should comply to the
definition of a xs:decimal of the XML schema language,
since the xs:decimal type does nog allow scientific
notation (xs:float and xs:double do).

Is it possible to alter the Value class in such a way that
numers are returned in non scientific notation?

If not, can this at least be done for integer type values,
so that round, floor and ceil return numbers that comply
with the definition of Integers in the XML Schema
language?

Add OutputURIResolver

Add an OutputURIResolver similiar to the one provided
by Saxon.

make filter-src="url(foo)" more flexible

Oliver Becker — Fri, 25 Mar 2005 11:20:57 -0000

The filter-src attribute is currently not dynamic.
Proposal: change the URL variant to 'url(' expr ')'.
Thus the filename may be evaluated at runtime.
