The Element.getElementsByTagNameNS()
method returns a live HTMLCollection
of elements with the given tag name belonging to the given namespace. It is similar to Document.getElementsByTagNameNS
, except that its search is restricted to descendants of the specified element.
Element.getElementsByTagNameNS()
Syntax
getElementsByTagNameNS(namespaceURI, localName)
Parameters
-
namespaceURI
is the namespace URI of elements to look for (seeElement.namespaceURI
andAttr.namespaceURI
). For example, if you need to look for XHTML elements, use the XHTML namespace URI,http://www.w3.org/1999/xhtml
. -
localName
is either the local name of elements to look for or the special value"*"
, which matches all elements (seeElement.localName
andAttr.localName
).
Return value
A live HTMLCollection
of found elements in the order they appear in the tree.
Examples
// check the alignment on a number of cells in a table in an XHTML document. var table = document.getElementById("forecast-table"); var cells = table.getElementsByTagNameNS("http://www.w3.org/1999/xhtml", "td"); for (var i = 0; i < cells.length; i++) { var axis = cells[i].getAttribute("axis"); if (axis == "year") { // grab the data } }

["The behavior of
element.getElementsByTagNameNS changed between Firefox 3.5 and Firefox 3.6. In Firefox 3.5 and before, this function would automatically case-fold any queries so that a search for \"foo\" would match \"Foo\" or \"foo\". In Firefox 3.6 and later this function is now case-sensitive so that a query for \"foo\" will only match \"foo\" and not \"Foo\". For more background on this, please see the
comment from Henri Sivonen about the change. You can also look at the
relevant part of the standard, which states which parts of the API are case-sensitive and which parts aren't.", "Before Firefox 19, this method was returning a
NodeList ; it was then changed to reflects the spec change."]
