XPathException

[Cogito]

Hallo zusammen,

ich bekomme an einer Stelle meines Programms eine XPathException mit folgendem Text:

Code:

************** Exception Text **************
System.Xml.XPath.XPathException: 'companies/company[displayName=Monterey Holdings I Sàrl]' has an invalid token.

Kann einer von euch mir sagen welches Token hier ungültig ist (ich vermute mal das es das Zeichen à ist) ?
