The way you've written it, you're asking the p:string-replace step to
evaluate the string-replace. That won't work because the variables aren't
in-scope inside the step. You want this:

  <p:string-replace match="root//text()"
    <p:with-option name="replace"
                   select="concat('replace(., &quot;text&quot;, '", $foo, "')")/>

Now the XProc processor expands teh value of $foo and passes it to
string-replace.

A bit ugly, but...

                                        Be seeing you,
