XML syntax equivalent

attribute

Description

The attribute pattern matches an attribute. The name of the attribute is defined using a nameClass, which may be either a single name or a name class. Note that, unlike the XML syntax, the content of an attribute doesn’t default to text and must always be explicitly defined.

Restrictions

• After simplification, attribute patterns can contain only patterns relevant for text nodes.

• Attributes can’t be duplicated, either directly or by overlapping name classes.

• Attributes that have an infinite name class (anyName or nsName) must be enclosed in a oneOrMore pattern (or zeroOrMore before simplification).

Example

attribute available { text }
attribute xml:lang { xsd:language }
attribute * - (local:* | lib:* | hr:*) { text }
