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:
xml
<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: While the property returns the case of the internal DOM storage, which is lower case, note that tagName
property returns upper case for HTML elements in HTML DOMs.
