Re: [xsl] Using variables to determine nodesets with conditions

Nodestes themselves don't have conditions, although a condition may have
been used to select the nodes. the variable stores the result (the set of
nodes) not the expression used to select it.

It does work, local-name() = $nodename is a string valued equality test
so $node-name will be coerced to a string by taking the string value of
the first node in document order in the set and comparing it with
local-name().

Howevr the variable binding you showed does not generate a nodeset at
all.
<xsl:variable name="nodename">PEOPLE/PERSON[NAME != 'Carlos']</xsl:variable>
just makes a result tree fragment with a root node and a text node with
the string "PEOPLE/PERSON[NAME != 'Carlos']" there is no way in XSLT to
evaluate an Xpath that is contained in a string, although some systems
have extension functions to do that.
However perhaps you want the node set selected by that expressuion,
which would be

<xsl:variable name="nodename" select="PEOPLE/PERSON[NAME != 'Carlos'"/>

then 
<xsl:for-each select="*[local-name() = $nodename]"/>

would work and be the same as

<xsl:for-each select="*[local-name() = current()/PEOPLE/PERSON[NAME != 'Carlos']]"/>

which would select all teh child elements whose local name was teh same
as the string value of the first PEOPLE/PERSON child whose NAME was not
Carlos.
