well working is good;-) as always, if you only use a variable once can (but don't have to) inline the definition, so here the global variable $foo is only used once so you could equivalently go <xsl:apply-templates select="/foo/bar"> <xsl:with-param name="foo"> <xsl:choose> <xsl:when test="condition1"> ...value if condition1 is true </xsl:when> <xsl:otherwise> ...value if condition1 is not true </xsl:otherwise> </xsl:choose> </xsl:with-param> </xsl:apply-templates> But it probably compiles to more or less the same thing. One of the nice features of side-effect free languages is that the compiler has a lot of freedom to re-arrange the code, if you use the same subterm multiple times the compiler can reuse the value, effectively implictly making a variable, conversely if you only use a variable once it can inline the definition, effectively removing the variable. So use of variables or not often just amounts to personal coding style aesthetics. dDavid -- google plus: https:/profiles.google.com/d.p.carlisle ________________________________________________________________________ The Numerical Algorithms Group Ltd is a company registered in England and Wales with company number 1249803.
