Names in XML, as you probably know, are case-sensitive, and xslt does
not have a case-insensitive compare.  The usual way to do a
case-insensitive compare is to use the the translate() function.  Here
as an example, where I create separate variables.  You do not have to do
this but it is more readable, and easier if you will be doing several
such compares.

<xsl:variable name='uppers'
   select='"ABCDEFGHIJKLMNOPQRSTUVWXYZ"'/>
<xsl:variable name='lowers'
   select='"abcdefghijklmnopqrstuvwxyz"'/>

The test in your predicate could be something like this ("first" is the
shorthand syntax for "child::first") -

translate(first, $uppers, $lowers) = "john"

Notice that you need quotes around the two translation strings,
otherwise they would be understood as element names rather than as
strings.
