Exemples

L’exemple suivant crée un message et des requêtes de message XPath.The following example creates a message and XPath message queries. Les requêtes sont évaluées par les objets XPathMessageQuery contenus dans un objet XPathMessageQueryCollection.The queries are evaluated by the XPathMessageQuery objects contained in an XPathMessageQueryCollection object. Les résultats de chaque requête sont testés à l'aide de la propriété ResultType de la classe XPathResult.The results of each query are tested using the ResultType property of the XPathResult class.
