[xsl] Escaping data in XML attributes

[Robert La Ferla <robertlaferla@xxxxxxxxxxx>]

I have an issue that I need assistance with:

Let's say that my database returns this XML unfriendly name that I  
need to insert into an XML document.

"Bob's Black & Tan "Boston Branch <1>"

As you can see, the value returned has double quotes, single quotes,  
angle brackets and an ampersand.

I could put the value in a child element of my company element like  
this:

<company>
<name><![CDATA["Bob's Black & Tan "Boston Branch <1>"]]></name>
</company>

but that would require a massive rewrite of my XSLTs and XML because I  
currently use attributes for values like name, etc...:

<company name="Bobs Black and Tan"></company>

and I have many elements similar to this like <account>, <employee>,  
etc...

Is there a way I can still use attributes yet escape these unsavory  
characters?  What's the most efficient way of solving this?
