You can't.
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> ...
<xsl:variable name="my_var"> <xsl:for-each select="Level_2"> <xsl:value-of select="./@Name"/> </xsl:for-each> </xsl:variable> <xsl:apply-template/>
Now myvar contains "Name_1Name_2...Name_n..." as a string. And I want to use it on the Level_2 match:

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.
