RE: How to use arrays in XSLT?

Hi,

> Can I use arrays in the XSLT program?

XPath doesn't have an array data type, but there are ways to get where you
want.

If you have a static array, then create something in the lines of

<x:map>
  <entry key="..." value="..."/>
  ...
</x:map>

and stick that inside xsl:stylesheet. Then define an xsl:key as

<xsl:key name="lookup" match="entry/@value" use="../@key"/>

and then do a look-up with

<xsl:variable name="key" select="get-key-value"/>
<xsl:for-each select="document('')">
  <xsl:value-of select=key('lookup', $key)"/>
</xsl:for-each>

There are other ways doing it, e.g. if you need to use a dynamic map or if you
use XSLT 2.0, but in that case you should describe your needs in more detail.
Hope this helps.
