XSLT doesn't do arrays of any sort. It does however do XML which is much
more fun, and allows more interesting structure than an array which is
of necessity rather rectangular.

if you have a map.xml that looks like

  <bar in="name1" out="MyName"/>
  <bar in="int4" out="finalInteger"/>

Then you can do

If the map file is big and you want the system to use a hashed lookup
use a key, map file as above but use

<xsl:key name="map" match="bar" use="@in"/>
<xsl:for-each select="document('map.xml')">
 <xsl:value-of select="key('map',name())/@out"/>
