The starting "/" for the root node. This could be obtained by changing the expression to: <xsl:value-of select="for $e in ancestor::node() return name($e)" separator="/" /> 2. The path has to include the current node. Therefore something like this will be required: <xsl:value-of select="for $e in ancestor-or-self::node() return name($e)" separator="/" /> but this will not work for non-element nodes... 3. Most important, positional information will not be included, so for example: /a/b[2]/c[3] will produce: /a/b/c 4. Maybe I'm wrong, but shouldn't this be: separator="'/'" ?
