New subject: [Pharo-project] Writing API for XML (WAX) - Bibliography example

Nov. 3, 2010


      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.

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

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?

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.

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

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.

Hannes
