I have the impression that I should also look at

    XMLPluggableElementFactory new handleElement: 'NOM' withClass: AAAName.

Because it looks like that I inject my nodes inside the dom

Am I correct?

Hi,

My original work only survived for the XMLDOMParser. See this example:

http://ws.stfx.eu/NK2WLSW99X10

(paste this in Spotter :))

For an XMLDOMParser, you can say that you want to instantiate a node in the DOM with an custom instance. For example, here I instantiate <NOM> with AAAName:

You are looking for something a bit different. In a way you want to associate the triggering of a specific handler when some XPath like expression is being matched for the current element. I think something like this should go in the main implementation.

Cheers,

Doru

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.

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>James</PRENOM>
         <NOM>Stewart</NOM>
         <INTITULE>John Ferguson</INTITULE>
       </ROLE>
       <ROLE>
         <PRENOM>Kim</PRENOM>
         <NOM>Novak</NOM>
         <INTITULE>Madeleine Elster</INTITULE>
       </ROLE>
     </ROLES>
     <RESUME>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,
