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... Alexandre

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.

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.

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. in fact for subnodes like role I should just continue the visit flow and get

But I will keep in mind XPath. It would be grtea to have tutorial on all these XML technologies - SAX - DOM - PullParser - XPath queries / Pastell - Opax It could be XML in Pharo a nice book

Pastell is an implementation of XPath. But I had a look at it many years ago (when I was extracting data from srcML xml files, you remember? :-) Alexandre

Hi hernan I do not what I want :). Irina a woman learning Pharo has a xml output from a tool (I have no idea what is inside :) and I thought ok this is a good idea to check a bit the solutions in Pharo. I will add your example to the PullParser Chapter. Because I like the Pull approach I'm doing a pass on OPAX package because it was cool too. Stef Le 12/3/16 09:53, Hernán Morales Durand a écrit :

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 := '<?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, 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... </RESUME> </FILM> <FILMS>'. 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.

Hi, I did OPAX :). At one point there was an effort around NodeFactory, and we chose to improve that one. Cheers, Doru

So I wonder why Fabrizio did OPAX do you have an idea? You get a simple tree but it is worth? I will finish my improvement on OPAX.

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.

Oh cool! I did not know there was a project XPath in Pharo. I learnt something. Cheers, Alexandre

XPath is better than Pastell. That is why in Moose we now have XPath.

I saw that Pastell is only tagged for Pharo30 and has not metadata. It would be good to revise it.
