Comentários

O documento XML a ser exibido no Xml controle é especificado de uma das três maneiras. Você pode especificar um System.Xml.XmlDocument objeto, uma cadeia de caracteres XML ou um arquivo XML definindo a propriedade apropriada. A DocumentSource propriedade é usada para especificar o caminho para um arquivo XML (representando um documento XML) a ser exibido no controle. Você pode usar um caminho relativo ou absoluto. Um caminho relativo relaciona o local do arquivo ao local da página Web Forms ou do controle do usuário, sem especificar um caminho completo no servidor. O caminho é relativo ao local da página da Web. Isso facilita a movimentação de todo o site para outro diretório no servidor sem atualizar o caminho para o arquivo no código. Um caminho absoluto fornece o caminho completo, portanto, mover o site para outro diretório requer a atualização do código.
