Hi Jose, Others have correctly pointed that variable scoping is limited to the context in question. If you declare a variable in xsl:for-each loop, you cannot access it outside the xsl:for-each loop. Unfortunately, variables don't propagate between contexts in XSLT.. For e.g. if you declare a variable x before xsl:for-each loop , and again declare the same variable x in xsl:for , then when control goes outside xsl:for , you don't get the value that was assigned in xsl:for-each .. Outside xsl:for-each, you will refer to x that was declared before xsl:for-each .. *This behaviour for variables sis imposed in XSLT to give a side effect free programming*.. >From the description of your problem, you may do some workarounds to access value generated in xsl:for-each ,outside the for-each.. for e.g. you may use xsl:call-template as below <xsl:for-each select="something"> <xsl:variable name="x" select="."/> <xsl:call-template name="printX"> <xsl:with-param name="temp" select="$x"/> </xsl:call-template> </xsl:for-each> <xsl:template name="printX"> <xsl:param name="x"/> <xsl:value-of select="$x"/> </xsl:template> There can be other workarounds also as others have pointed.. If you tell us your exact problem, somebody here can tell you the best way to solve in XSLT..
