Hi alex
I do not know :)
I like visitor because they are better than a series of if.
So I will see. I would like to help people to extract their information
easily.
May be inside the visitNode I could use XPath (do you know what is the
constraint to use XPath)
does it work on dom objects?
I would like to have something like that (being able to use some node to
perform custom actions)
Now I do not see how from one visit method I can access the other. and
if I do not do it in the visit
what is the information I should store (like parent link) to be able to
identify that a given role is associated to a given film.
visitFilm
title := self extractFromChildren: #Titre.
pays := self extractFromChildren: #Pays.
self newFilm: title from: pays.
visitRole
<FILM annee="1958">
<TITRE>Vertigo</TITRE>

Hi Stef,
I have the impression that a visitor is not the ideal solution to query XML
tree. It works well in some case, and it is disastrous in some other.
XPath is the way to query XML data. As far as I know, there is no complete
support. Pastell was a nice try however...

Thanks
Ok it was characters: I will try it
What a bad name!
I will probably have to build a stack or dictionary of dictionary of the part
that I will not want to visit but this is another story :)

Hi,
The qualified name in function startElement: aQualifiedName attributes:
aDictionary, will be FILMS and after FILM and after TITRE,...etc...
So, you have to tell to your shouldVisit: method to accept TITRE too and get in
and after you should implement characters: to get the content on the tag.

Objet : [Pharo-users] How to access XML tag name?
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 <TITRE>Vertigo</TITRE> where I can get the
Vertigo information.
I redefined several methods of SAXhandler but without success.
