However, there seems to be something rather awkward about the structure <xsl:for-each select="$nodes"> ... <xsl:apply-templates select="." mode="different-mode"> <xsl:with-param name="pprec" select="preceding-sibling::*" /> <xsl:with-param name="pfoll" select="following-sibling::*" /> </xsl:apply-templates> </xsl:for-each> which seems more or less what you're trying to do. The reason for my thinking so is the fact that the preceding- and following-sibling axes will *per se* be available from within the matching template, since the context node will be changed by the apply-templates --I'm absolutely dazzled as to why you would want to pass these in as parameters... The above just needs to become: <xsl:apply-templates select="$nodes"> <xsl:with-param name="pparam" select="expr" /> </xsl:apply-templates> where the param is used to collect data which is easily accessible from the context surrounding the apply-templates, but won't be too easily reachable from within the context of the matching template. Hope this gives you an idea (or two)! Cheers, Andreas
