[AtulTiwari]

i know that what is namespace in xml why it is used?
but i don't know how it is used?

in the below example i know that we are declaring a namespace(alias ) h and f for seprating the table tag but what is "room" and what the URI means
i.e "<room xmlns:h="http://www.w3.org/TR/html4/" what it means?

Can any one please explain the terms...

<room xmlns:h="http://www.w3.org/TR/html4/"
xmlns:f="http://www.w3schools.c om/furniture">

<h:table>
<h:tr>
<h:td>Apples</h:td>
</h:tr>
</h:table>

<f:table>
<f:name>Afric an Coffee Table</f:name>
<f:width>80</f:width>
<f:length>120 </f:length>
</f:table>

It looks like you have the room in the default namespace, and are declaring a namespace h, which points to http://www.w3.org/TR/html4/, an html namespace.

I think it should probably be <f:room>, since you probably want the room in the furniture namespace.


we use <h:table> to represent an html table.
we use <f:table> to represent the furniture table.

If we didn't have these namespaces, then if we saw an element table, which table would it be? html or furniture?
