DESCRIPTION

Arguments passed to and the value returned from an XLST function will be of type of one of the classes derived from XML::Xalan::XObject: XML::Xalan::Boolean, XML::Xalan::Number, XML::Xalan::String, XML::Xalan::NodeSet, or XML::Xalan::Scalar.

XML::Xalan::NodeSet

All location path expressions will return an object of this type, even if the expression only returns a single attribute or a text node (node set with one member).

Methods

$nodeset->number()

Returns the numeric representation (a numeric scalar).

$nodeset->string()

Returns the stringified nodeset (a string scalar).

$nodeset->boolean()

Returns the boolean representation.

$nodeset->get_nodelist()

Returns a list of XML::Xalan::DOM node objects.

XML::Xalan::String

XSLT string() function returns an object of this type.

Methods

$string->value()

Returns the string value.

XML::Xalan::Number

XSLT number() function returns an object of this type.

Methods

$number->value()

Returns the numeric value.

XML::Xalan::Boolean

XSLT conditional expression returns an object of this type.

Methods

$bool->value()

Returns the boolean value.

XML::Xalan::Scalar

A Perl scalar. Useful if your extension function returns a value which doesn't suit to any of the above XSLT built-in data types, for example a blessed reference.

Methods

$scalar->value()

Returns the scalar value.
