.)
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:svg="http://www.w3.org/2000/svg">
<head>
<script type="application/javascript"><![CDATA[
function test() {
var text = document.getElementById('text');

</svg:svg>
<textarea id="text" rows="4" cols="55"/>
</body>
</html>
Notes
The local name of a node is that part of the node's qualified name that comes after the
colon. Qualified names are typically used in XML as part of the namespace(s) of the
particular XML documents. For example, in the qualified name
ecomm:partners
, partners
is the local name and
ecomm
is the prefix:
<ecomm:business id="soda_shop" type="brick_n_mortar" xmlns:ecomm="http://example.com/ecomm">
<ecomm:partners>
<ecomm:partner id="1001">Tony's Syrup Warehouse
</ecomm:partner>
</ecomm:partner>
</ecomm:business>
Note: In Gecko 1.9.2 and earlier, the property returns the
upper-cased version of the local name for HTML elements in HTML DOMs (as opposed to
XHTML elements in XML DOMs). In later versions, in compliance with HTML5, the property
returns in the case of the internal DOM storage, which is lower case for both HTML
elements in HTML DOMs and XHTML elements in XML DOMs. The
tagName
property continues to return in the upper
case for HTML elements in HTML DOMs.
