How to use href in XML?

[LarryChen]

I have a data containing a href in XML like the following,


<tag> If you don't understand this, please use <a href = "www.google.com"> this site </a> to find out </tag>

But it doesn't work. I wonder how to make it work? Thanks.

add the http:// like so:
<a href="http://www.google.com">this site</a>
