Hinweise

Das XML Web Services Discovery-Tool führt die Ermittlung der verfügbaren XML-Webdienste anhand eines URL aus. Der URL verweist typischerweise auf ein Discoverydokument, das i. d. R. die Dateierweiterung .disco aufweist. Das Discoverydokument (ein XML-Dokument) enthält Verweise auf Informationen über das Vorhandensein von XML-Webdiensten. Hierbei kann es sich um eine Dienstbeschreibung, XSD-Sprachschema (XML Schema Definition-Sprachschema) oder ein anderes Discoverydokument handeln. Diese Klasse stellt den Inhalt des Discoverydokuments dar, wobei die References-Eigenschaft eine Liste der im Discoverydokument enthaltenen Verweise enthält.

Beispiel

Im folgenden Codebeispiel wird unter Verwendung von Read ein Discoverydokument aus einer Datei ausgelesen, und unter Verwendung der Write-Methode werden Daten in eine Datei zurückgeschrieben.
