HI cdrick thanks for your reply i will tell you in detail. This is the actual DAML sentence (input) given to the XMLParser <daml:Class rdf:ID = "Person"> <rdfs:subClassOf rdf:resource = "#Animal" /> rdfs:subClassOf daml:Restriction <daml:onProperty rdf:resource = "#hasParent" /> <daml:toClass rdf:resource = "#Person" /> </daml:Restriction> </rdfs:subClassOf> </daml:Class>
<person rdf:ID = "Joe"> <hasParent rdf:resource = "#John"/> </person>
Iam parsing this using the code | stream | [ | tree | stream := FileStream fileNamed: 'test.daml'. tree := XMLDOMParser parseDocumentFrom: stream. tree elements collect: [:each| each name]. ] ensure: [stream close].
From the above code, "tree elements collect: [:each | each name]." actually collects the root elements. for example from the above example it collects daml:class and <person>. My aim is to collect all the elements including attributes and attribute values from that parsed tree in a sequeanceable order.
show us the result you'd like for the example sentence...
After collecting it in a sequence i have to store it in a variable, so that i can check with that elements with other conditions.
Not sure (and not expert), but I think you should use the SAXParser so that you navigate the xml tree and do whatever you want with elements/attributes... The DOMParser is actually building a full tree for further exploration... can be long and you have to process it again to get more information... I dit that once to collect wheteher data for a large xml file... The process is maybe not obvious, you need to subclass SAXHandler with say DAMLHandler, where you'll redefine messages likes characters: startDocument: endElement: startElement:attribute:list:... but the better is probably to subclass, then you put a self halt in the method startDocument: and little by little you see how it works... Also, you'll probably have to create a class where you'll store the information you want (Meteo class in my case...)... Sorry, but I cannot help you more on this... really busy for some monthes :'(

ps: I joined my meteo handlers, of course it won't work but it will give you another example of SAXHandler (that the XMLDOMParser which is a particular case of SAXHandler)... soory for the bad code :p
