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

And this

does not really help me.

Because in SAXHandler I have

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.

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.

<?xml version="1.0" encoding="iso-8859-1"?>
<FILMS>
�� <FILM annee="1958">
�� <TITRE>Vertigo</TITRE>
�� <GENRE>Drame</GENRE>
�� <PAYS>USA</PAYS>
�� <MES idref="3"/>
�� <ROLES>

�� <ROLE>
�� <PRENOM>Kim</PRENOM>
�� <NOM>Novak</NOM>
�� <INTITULE>Madeleine Elster</INTITULE>

�� <RESUME>Scottie Ferguson, ancien inspecteur de police, est sujet
au vertige depuis qu'il a vu mourir son
