[xsl] using attribute value as an attribute name OR using element value as an attribute name

[ross at webwolves dot com]

Folks,

I have a list of columns in a config block, and some data in row tags, as
shown below:

<?xml version="1.0"?>
<root>
	<config>
		<columnList>
			<column name="column1"/> <!-- could change to element text instead of
attribute
			<column name="column2"/>
			<column name="column4"/>
		</columnList>
	</config>

	<row column1="c1r1" column2="c2r1" column3="c3r1" column4="c4r1"/>
	<row column1="c1r2" column2="c2r2" column3="c3r2" column4="c4r2"/>
	<row column1="c1r3" column2="c2r3" column3="c3r3" column4="c4r3"/>
	<row column1="c1r4" column2="c2r4" column3="c3r4" column4="c4r4"/>
	<row column1="c1r5" column2="c2r5" column3="c3r5" column4="c4r5"/>

</root>

What I want to dow is iterate the rows, only showing those columns defined
in config/columnList. Seems easy, but I've been going mad trying to figure
out how. :-)

I would be insanely grateful for whatever help anyone can provide. Without
help, I'm merely insane. :-)


Thanks.
