replacing a string in a nodeset

I am looking to take a series of nodes, replace some strings, and end up
with a series of nodes.

basically what I have is the following

<date>xxxx0101</date>
<date>20020405</date>
<date>xxxx0706</date>

I want to replace all the 'xxxx' with 2002, and end up with 3 node nodeset
that I can then use elsewhere in my XSL (I would store it in a variable)

I am able to grab the nodes with xxxx in them easy enough

 <xsl:variable name='rlist' select="//date[contains(.,'xxxx')]"/>

rlist will be a 2 node node-set.

Can I replace the strings and then do a union (|) of rlist and my base
nodeset?
