fn:namespace-uri-from-QName( QName? $srcval) → anyURI?
Function signature
$srcval |
xs:QName ? |
Result |
string ? |
Extracts the namespace URI component of a QName value
Note:The old name get-namespace-from-QName [sic] is retained as a synonym. Changed in Saxon 8.1 to return a zero-length string rather than an empty sequence if the QName is in no namespace (this change occurred between the May 2003 and November 2003 drafts of the specification.)
