> I need know value of variable IsSubclass before the tag > </xsl:template> Like all programing languages, variable definitions have a defined scope in xslt and in this case the variable IsSubclass goes out of scope at the end of the xsl:if element so it is out of scope and does not have a value at teh end of the template. > I need do some things which depends on the value of the one variable. This can not be the case, there is no computation that requires global updatatable variables, the expressive power of imperative languages with such constructs is exactly the same as that of declarative languages without them. If you gave some indication of the problem you are trying to solve someone could show how to do it in xslt. Taking a wild guess I would think that you want a test to be true if there is any child node with the requested name, in which case you don't need a for-each loop, or any variables at all, just do <xsl:param name="subclass" select="'subClassOf'"/> ... <xsl:if test="*/local-name()=$subclass">.... Note I also switched to just testing teh local name as depending on specific namespace prefixes is inherently risky.
