Pourquoi la validation XSD fonctionne-t-elle toujours pour ce fichier?

Question

Le fichier xml suivant semble toujours valider. Je ne sais pas pourquoi, mais quand je supprime le suivant 'xmlns = "urn: schémas-microsoft-com: bureau: tableur"', il semble lancer une erreur de validation comme prévu. D'une manière ou d'une autre, MS empêche la validation avec le schéma XSD office ajouté. Ainsi, chaque fois que XSD Schema est inclus, vous ne pouvez pas valider XML en utilisant le framework .NET.

Answer 1

travaillé dans mon Abonné cas:

settings.ValidationFlags = XmlSchemaValidationFlags.ReportValidationWarnings 

Attention cependant, il peut soulever d'autres erreurs normalement ignorées.

Answer 2

Vous faites référence à cet espace de noms ici:

<Worksheet ss:Name="Not 8 Counts"> 
    <Table ss:ExpandedColumnCount="8" ss:ExpandedRowCount="8" x:FullColumns="1" x:FullRows="1"> 

avec x: x: FullColumns et FullRows

Answer 3

Votre xsd est sans effet. La feuille de calcul xsd pour urn: schemas-microsoft-com: office: est extraite d'ailleurs, probablement intégrée au framework .net, et utilisée même si vous n'avez pas explicitement indiqué au validateur où la trouver. Ceci est autorisé dans les règles de validation du schéma.
