[xsl] adding escaping slashes

[Joe Stump <joe@xxxxxxxxxxxx>]

I've got some text (ie. <b>Joe's Diner</b>) that needs to be  
translated into something along the lines of the following:

<a onClick="doSomething('Joe\'s Diner');">Joe's Diner</a>

I've got everything working, but how to do the equivalent of PHP's  
addslashes() to the text() of an element is causing me some problems.  
Anyone have any ideas how to add escaping slashes to a text node?

Thanks!
