You can't.
I understand.
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.
I'm using the following XML input document :
...
<Level_1 Name="Name_1">
...
</Level_1>
...
<Level_1 Name="Name_n">
<Level_2 Name="Name_2">
</Level_2>
...
<Level_2 Name="Name_n">
</Level_2>
...
</Level_1>
...
The following code puts on "my_var" the totality of the Name attributes of
each element "Level_1" :
<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:apply-template/>
</xsl:template>
Now myvar contains "Name_1Name_2...Name_n..." as a string.
And I want to use it on the Level_2 match:
<xsl:template match="Level_2">
<!-- Here I would like to use my_var but I can't cause I'm out of "my_var"
scope -->
<!-- Do you know how can I recover "Name_1Name_2...Name_n..." ? -->
</xsl:template>

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.
