Remarques

La correspondance de modèle de texte permet à un service Web XML de tirer parti du contenu HTML existant en l’analysant à l’aide d’expressions régulières. un service Web XML spécifie le contenu qu’il souhaite analyser dans une description de service à l’aide d’éléments de correspondance. Ces éléments de correspondance spécifient plusieurs éléments : l’expression régulière pour analyser le contenu d’une page HTML existante, si l’analyse doit respecter la casse et combien d’instances de contenu correspondant à l’expression régulière doivent être retournées. Lorsqu’un client génère une classe proxy à l’aide de l’outil Wsdl.exe, les méthodes de la classe proxy incluent un MatchAttribute détail des éléments de correspondance trouvés dans la description du service.
