Long string - inserting a space after every 10 characters

Hi,

Is it possible to insert a space in a string (of unknown length) after a
specified number of characters e.g. after every 10 characters insert a
space??

I have an XML element called <name> which can be anywhere between 1 and 50
characters long. I need to either split it (by inserting a <BR/> tag) or
inserting a space (&#160;) after every 10 characters.

Example1:
<name>Thisisareallyreallylongnamedontyouthink</name>

Would look like:
Thisisarea<BR/>llyreallyl<BR/>ongnamedon<BR/>tyouthink

OR /

Example2
<name>Thisisanotherexceptionallylongname</name>

Would loook like:
Thisisanot&#160;herexcepti&#160;onallylong&#160;name

Many, many thanks
Al
