Writing API for XML (WAX) - Bibliography example

Hannes Hirzel
Hello

I read the post by Stephane Ducasse about writing XML (see below) with
a bibliography example.

Recently I (re)-discovered the port to Squeak/Pharo of the Writing API
for XML (WAX) (http://java.ociweb.com/mark/programming/WAX.html) and
could put it to good use for writing an XML file a bit more complex
than the bibliography example.

From the web site
 WAX has the following characteristics:

    * focuses on writing XML, not reading it
    * requires less code than other approaches
    * uses less memory than other approaches
      (because it outputs XML as each method is called rather than
      storing it in a DOM-like structure and outputting it later)
    * writes all XML node types
    * always outputs well-formed XML or throws an exception unless
running in "trust me" mode
    * knows how to associate DTDs, XML Schemas and XSLT stylesheets
with the XML it outputs
    * is well-suited for writing XML request and response messages for
REST-based and SOAP-based services

However I do not know how far these points apply to the Squeak/Pharo port.
http://www.squeaksource.com/WAX
It needs the VB Regex package (http://www.squeaksource.com/Regex)

As an exercise I did the code to produce the example Stephane gave. It
worked fine; see below.

Regards
Hannes

Re: Writing API for XML (WAX) - Bibliography example

Stéphane Ducasse
Thanks hannes
I think that the XMLWriter offers a bit something similar influenced by seaside DSL.

Re: Writing API for XML (WAX) - Bibliography example

Hannes Hirzel
Thank you Stef, for pointing this out.

I had a look at Torsten's email of July 6th about XMLWriter and the
subsequent discussion.

Yes, an alternative approach would be to model an XML  generation API
along the lines of Seaside html rendering -- with blocks instead of
start/end messages.

Has there some work going on elsewhere besides what Torsten did?
http://squeaksource.com/PharoGoodies/XMLWriter-tbn.5.mcz

--Hannes

N.B. This is only about 'XML writing' NOT about XML parsing. The idea
is to have an API which allows to have readable XML generation code
with an implementation which does not consume much memory. And with
enough examples and tests.

Re: Writing API for XML (WAX) - Bibliography example

Hannes Hirzel
Is XMLWriter in the upcoming 1.2 image? It is not in the 1.1 image.

Re: Writing API for XML (WAX) - Bibliography example

No we consider it as an external package.
Now we will have specific dedicated repositories for each version where configuration and all their packages will be published
so that people can have distribution of working code.

To load the thing:

Gofer new
                squeaksource: 'XMLSupport';
                package: 'ConfigurationOfXMLSupport';
                load.
(Smalltalk at: #ConfigurationOfXMLSupport) perform: #loadDefault

The new XML writer is in the more recent versions, from version 96 on, but at the moment you have to download it manually through Monticello or from the XMLSupport page on squeaksource.com, as the most recent Metacello configuration still points to v. 93. I'll try to update it shortly.

Re: Writing API for XML (WAX) - Bibliography example

Hannes Hirzel
Jaayer,

Thanks, I checked out

MCHttpRepository
    location: 'http://www.squeaksource.com/XMLSupport'
    user: ''
    password: ''

and looked at
XML-Parser-tg.101


Right version?


the class comment of XMLWriter



This class allows you to generate well-formed XML documents using an
API similar to Seaside's canvas and tag brush API.

Markup can be created by sending an instance any of the messages under
"writing markup." The messages that take no arguments return an
instance of an XMLMarkupWriter subclass. These objects can be
configured with messages like #name: and #attributeAt:put:. Sending
them #write or a specific writing message that accepts markup to embed
within (#content: or #internalSubset: for example) causes the markup
writer's configuration to be committed and its markup written to the
output stream. For markup writers that can have embedded markup, the
argument to the writing message can be a string, collection (of
strings and blocks), a block, or nil. The block passed in can
optionally take an argument, which will be the XMLWriter object that
created the markup writer object. Within the block you can generate
additional, child markup that will be contained by the parent.
Creating additional non-embedded markup will cause any unwritten
markup from a previous markup writer to be written, as will sending an
XMLWriter or XMLMarkupWriter #contents, #asString, #printOn:, or
#write.

Here is an example, which you can highlight and evaluate with cmd-p to
see the result:

        | writer |
        (writer := XMLWriter new) enablePrettyPrinting.
        writer xml.
        writer tag
                        name: 'foo:bar';
                        xmlnsAt: 'foo' put: 'http://foo';
                        attributeAt: 'a' put: 'one';
                        attributeAt: 'b' put: 'two';
                        content: [
                                writer tag: 'bar' content: [
                                        writer
                                                string: 'test';
                                                tag: 'baz';
                                                tag: 'foobar' content: 'test']]


Nice, as I know the Seaside html builder pattern. It is the same.


Remark: I think it should be in its own package

Instead of

    XML-Parser-Writers

I'd like to have

    XML-Writer

because writing has nothing to do with parsing.

However at this point it is minor cosmetics.

Another remark: An example using tags like name, author, title would
be helpful as well in the class comment because one sees more easily
what is going on.

For the current problem at hand I have started using WAX and I think I
will continue to do so. One reason it that I might want to port my App
to Java when finished prototyping in Smalltalk.


MCHttpRepository
    location: 'http://www.squeaksource.com/WAX'
    user: ''
    password: ''

I have not found XMLWriter tests whereas WAX has a considerable number of them.

As for XMLWriter, I surely will look at it again in a few months time.


Regards
Hannes
