element-available


The element-available function determines if an element is available and returns true or false.

Syntax

element-available( QName )

Arguments

QName
Must evaluate to a valid QName. The QName is expanded into an expanded-name using the namespace declarations in scope for the expression.

Returns

Otherwise, it refers to an extension element. If the expanded-name has a null namespace URI, the element-available function will return false.

Defined
