xsd.exe e xsd problema

[giuseppe500]

ciao.
Ho il seguente xml ex.xsd:

<?xml version="1.0" encoding="UTF-8"?>

il problema è che se provo a lanciare
xsd ex.xsd mi da quest' errore:

Errore: Errore durante la generazione di classi per lo schema 'ex'.
- Schema con targetNamespace="urn:iso.org:standard:10303art(28):version(2):x
mlschema:common" con sintassi non valida. Elemento simpleType 'urn:iso.org:stand
ard:10303art(28):version(2):xmlschema:common:Seq-anyURI' già dichiarato. Riga
106, posizione 3.
- Elemento simpleType 'urn:iso.org:standard:10303art(28):version(2):xmlschem
a:common:Seq-anyURI' già dichiarato.

Sono uno schema per l'ifc http://www.iai-tech.org/products/ifc...elease/summary io vorrei creare le classi in c# a partire dallo schema.

ma non riesco a capire l'errore , che deriva comunque dall include(se provo a toglierlo funziona) e i namespaces tipo targetnamespace o ad es xmlns:ex="urn:iso.org:standard:10303art(28):version(2):xmlschema:common".
a cosa servono?

grazie.

Io non ho mai utilizzato questo tool ma ti faccio una domanda, lo sai che
le classi si creano da solo quando crei il dataset?

l'xsd lo hai creato con il designer di visual studio?

[giuseppe500]

grazie.
no , le classi si creano anche con l'attributo /classes del tool xsd .
Ed è proprio quel che voglio fare.

[albgen]

no è la risposta alla prima o alla seconda domanda?
perchè stai utilizzando questa utility? cosa dovresti fare?

[giuseppe500]

devo creare la struttura delle classi in base allo schema xsd , per questo uso quell' utilitiy , non mi interessano i dataset .
Mi serve per deserializzare degli xml e andare automaticamete a popolare le classi che ho generato con l'xsd.
spero di essere stato un po piu chiaro , scusa se non lo sono stato.ciao.

[giuseppe500]

l'errore era che i targetnamespace dovevano essere uguali tra l'incluso e l'inclusore.
adesso ho un altro problema:
questi sono i miei schema:
1)IFC2X3.xsd
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" xmlns:ex="urn:iso.org:standard:10303art(28):version(2):xmlschema:common" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns:ifc="http://www.iai-tech.org/ifcXML/IFC2x3/FINAL" attributeFormDefault="unqualified" targetNamespace="urn:iso.org:standard:10303art(28):version(2):xmlschema:common">
2)ex.xsd
<xs:schema xmlns:ex="urn:iso.org:standard:10303art(28):version(2):xmlschema:common" xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="urn:iso.org:standard:10303art(28):version(2):xmlschema:common" elementFormDefault="qualified" attributeFormDefault="unqualified">
3)configuration.xsd
<xs:schema
targetNamespace="urn:iso.org:standard:10303art(28):version(2):xmlschema:common"
xmlns:ex="urn:iso.org:standard:10303art(28):version(2):xmlschema:common"
xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="qualified">

IFC2x3 include ex con:<xs:import schemaLocation="ex.xsd"/>
mentre ex.xsd include configuration con
<xs:include schemaLocation="configuration.xsd"/>

in IFC2x3.xsd ho i due attributi(non so bene come sichiamano) ifc: e ex: , questi come li devo impostare?
se li imposto tutti e due uguali ricevo uno stack overflow.
a cosa servono questi attributi?tipo xmlns:ifc="http://www.iai-tech.org/ifcXML/IFC2x3/FINAL" , ho visto che dopo nel codice sono dichiarati prima di un entity ad es.

grazie
