/[a-zA-Z0-9\._]*local.xml/.match('xpl.xml, demoUK.xml,
met_local.xml,cfg.xml')[0]
should work. just add any chars that are allowed in names to the []
portion of the regex, you should be all good.
or,
'xpl.xml, demoUK.xml, met_local.xml,cfg.xml'.split( "," ).select { |c|
/local.xml/ =~ c }
which would return an array of all instances that matched in the input.
