Re: How can I use a variable out of it scope ?

I see.
<xsl:template match="Level_1">

	<xsl:variable name="my_var">
		<xsl:for-each select="Level_2">
			<xsl:value-of select="./@Name"/>
		 </xsl:for-each>
	</xsl:variable>

	<xsl:variable name="my_var">
		<xsl:for-each select="Level_2">
			<xsl:value-of select="./@Name"/>
		 </xsl:for-each>
	</xsl:variable>
</xsl:template>

You can't.

Some processors have extension functions that allow this (saxon:assign
being one of the guilty parties) but the design of XSLT is totally
influenced by the fact that it is a side effect free language.

It's not that imperative programming is necessarily evil, but if you
want to program in that style it makes more sense to use a language that
has assignment statements (omnimark, perl, ....) rather than trying to
twist a language that does not.

If you said what you were trying to do at a higher level, perhaps
someone may suggest how it would be done more naturally in XSLT.
