Do you need to insert nationalized strings in a Form and List module on Dotnetnuke 5?
Here is the solution:
<xsl:variable name="currentCulture" select="//udt:Context/udt:CurrentCulture" />
<xsl:if test="$currentCulture='it-IT'">
Italian text
</xsl:if>
<xsl:if test="$currentCulture='en-US'">
English text
</xsl:if>
Hope it helps…
