XSLT Reference
local-name-from-QName()
Returns the local part of an xs:QName value as an xs:NCName.
Syntax
local-name-from-QName(qname)Description
local-name-from-QName() extracts the local part of an xs:QName value. The local name is the part after the colon in a prefixed name, or the entire name when no prefix is present. The result is an xs:NCName (a non-colonized name), which is a subtype of xs:string.
This function works with xs:QName values — typed values produced by QName(), resolve-QName(), or schema-validated content — not raw string representations of names. If the argument is the empty sequence, the empty sequence is returned.
Parameters
| Parameter | Type | Required | Description |
|---|---|---|---|
qname | xs:QName? | Yes | The QName from which to extract the local name. |
Return value
xs:NCName? — the local part of the QName, or the empty sequence if the argument is empty.

Notes
local-name-from-QName()operates on typedxs:QNamevalues, not on string representations. To get the local name of a node, uselocal-name()instead.- The result is identical to
local-name()on a node whose expanded name matches the QName. - When working with dynamically constructed QNames, this function is the companion to
namespace-uri-from-QName()andprefix-from-QName().
