InvalidQueryException für XPath-Abfrage mit numerischem Knotennamen

Problem, Frage

Sie erhalten die folgende Ausnahme, wenn Sie versuchen, eine Xpath-Abfrage auszuführen, die einen Knoten enthält, dessen Name mit einer Ziffer beginnt.

Auflösung, Antwort

Verwenden Sie diese Methode, um den Namen des numerischen Knotens mit der folgenden Methode zu codieren: org.apache.jackrabbit.util.ISO9075.encode(name)
Alternativ können Sie JCR-SQL anstelle von XPath verwenden.

Gilt für

CRX 1.x
