Element.getElementsByTagNameNS()
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.
Syntax
elements = element.getElementsByTagNameNS(namespaceURI, localName)
elements
is a liveHTMLCollection
of found elements in the order they appear in the tree.element
is the element from where the search should start. Note that only the descendants of this element are included in the search, not the node itself.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
).
Example
// 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
}
}
