XML finding namespace inside namespace

Question

I have this code :

<st:friend xmlns:st='areacode:819'>
<st:name xmlns:st='urn:555'>Company</st:name>
<type>B</type>
</st:friend>

Can someone explain me why st is declared twice?

Thanks, (Yes I forgot the </sr:friend> at the end. But it's exactly what I was looking for, to understand, the urn:555 goes to ! <br> thanks again @Bruno — baronming

Your XML example isn't well formed as it does not close the <st:friend> element but I'll assume that you meant to close it after the <type> element.

What is going on here is that the <st:name> element is redefining what namespace the st prefix refers to (to urn:555). This definition applies to the <st:name> element only (and would apply to child elements too if there were any). Once you are past the closing tag <st:name/>, the st prefix refers again to its original namespace (areacode:819).
