Subject: RE: [xsl] sum function and math expressions From: "Michael Kay" <mike@xxxxxxxxxxxx> Date: Fri, 8 Apr 2005 12:21:19 +0100 |
In general XSLT transformations are not reversible. For example, the following transformation is obviously non-reversible: <xsl:template match="/"> <z><xsl:value-of select="count(//*)"/></z> </xsl:template> There may be some transformations that are reversible, but as with any other programming language, you will have to write the reverse transformation by hand.
