Hi,

I did OPAX :).


:)
So I'm doing a pass and cleaned it.
I created a small builder to generate subclasses and tags. I will 
release it soon.

I will play with the FILMS xml to understand what can be a solution.

Then after I will check a bit more the pluggable.


At one point there was an effort around NodeFactory, and we chose to improve 
that one.

This class is a pluggable factory that can map elements to different XMLElement 
subclasses based on the name and namespace information of those elements. You 
have to create an instance, configure it to handle certain elements with 
certain classes, and then inject your instance into a DOM parser using 
#nodeFactory: before parsing. Here is an example of its use:

doc := (XMLDOMParser on: someXML)
nodeFactory:
(XMLPluggableElementFactory new
elementClass: GenericElement;
handleElement: 'user' withClass: UserElement;
handleElement: 'report' withClass: ReportElement;
handleElement: 'report' namespaceURI: 'urn:specialreprot' 
withClass: SpecialReportElement)
parseDocument.

The #handleElementsMatchingClass*: forms try to match elements to the specified classes 
based on the names of those classes when stripped of any prefix (like XML) and 
"Element" suffix and converted to both camel case and a hyphenated form. So 
this:
XMLPluggableElementFactory new
handleElementsMatchingClass: MYRootUserElement

will handle 'rootUser' and 'root-user' elements with the MYRootUserElement 
class.

Hi,

Yes, exactly. You get a qualified DOM with a hierarchy that you can afterwards 
visit.

Only the current implementation only works only with the XMLDOMParser. It does 
not work with SAX.

Hi

Yesterday I started to hack a smart SAX handler. The idea is that 
I want to just
specify the tags I want to visit and the SAX handler should invoke 
(generated)

visit methods. Like that I can easily get visitors on XML domain.

Here is an example of what I did.

  | h |
  h := SmartSAXHandler new
  visitor: (MyFilmVisitor new visitTags: #(FILM 
ROLE));

  on: FileSystem workingDirectory / 'FILMS.XML'.
  h parseDocument.
  ^ h



SmartSAXHAndler >> startElement: aQualifiedName attributes: 
aDictionary


  (visitor shouldVisit: aQualifiedName)
  ifTrue: [
  visitor
  perform: (visitor createdVisitSelector: 
aQualifiedName)

  with: aQualifiedName
  with: aDictionary
  ]


Object subclass: #GenericTagSAXVisitor
  instanceVariableNames: 'visitTag visitTags'
  classVariableNames: ''
  category: 'SmartXMLHandler'


GenericTagSAXVisitor>>visitTags: aCollection
  "set the tags that will lead to a call to a visitTag:with: 
method in the visitor"


  visitTags := aCollection collect: [ :each | each asLowercase ].
  self createVisitMethods.

and in a subclass the visit* methods automatically generated


Now I could not get when I have a Vertigo where I 
can get the

Vertigo information.
I redefined several methods of SAXhandler but without success.

Re: [Pharo-users] How to access XML tag name?

2016-03-12 Thread Hernán Morales Durand

Hi Stephane,

Do you want to extract subtree from a XML?
Or just extract the text in specific nodes?

I think StAX parser is more friendly for selecting nodes (you don't have to
subclass), i.e.:

| parser doc |
doc := '

  
Vertigo
Drame
USA


  
James
Stewart
John Ferguson
  
  
Kim
Novak
Madeleine Elster
  

Scottie Ferguson, ancien inspecteur de police, est sujet
au vertige depuis qu''il a vu mourir son
 collegue. Elster, son ami, le charge de surveiller sa femme, Madeleine,
ayant des tendances
 suicidaires. Amoureux de la jeune femme Scottie ne remarque pas le piege
qui se trame autour
 de lui et dont il va etre la victime... 
  
'.
parser := XMLPullParser parse: doc.
[ parser isEndDocument ] whileFalse: [
parser
if: 'FILM'
peek: [ : found |
Transcript show: found name , ' -> ' , found attributes
asString; cr.
parser next.
Transcript show: parser tagName ].
parser next ]

Anyway if you want to try with SAX, have a look at #test01ParsingNodes and
add some halts in BioNCBIBlastSAXParser to see it in action (that's in
BioSmalltalk). I didn't used visitors though.

Re: [Pharo-users] How to access XML tag name?

2016-03-12 Thread stepharo

This is more complex than that.
Because I would like to have a visitor generated from the token I give.

And this
start
character
end

does not really help me.

Because in SAXHandler I have
start
where I should store the properties
same in characters:
to store the name
end
where I should invoke the visitor

Now it means that I should only store the information for the tag I want.
Does anybody already did that and publish it?
I know doru did that in the past.
I will try.
