Subject: Re: [xsl] Can I change variable contents. From: David Carlisle <davidc@xxxxxxxxx> Date: Thu, 8 Apr 2004 13:10:47 +0100 |
> One general Question: If we can't change xsl:variable, then why it is > named variable? is should be xsl:constant. the use of the word "variable" matches its original use in mathematics not the slightly strange use in imperative programming languages that allow constructs such as x = x + 1 but don't allow you to subtract x from both sides of that equation and deduce 0 = 1 something like <xsl:for-each select="Tag[starts-with(@value,'grade:')]"> <xsl:value-of select="substring-after(@value,'grade:')"/> <xsl:text> </xsl:text> </xsl:for-each> from grade <xsl:for-each select="Tag[starts-with(@value,'sub:')]"> <xsl:value-of select="substring-after(@value,'sub:')"/> <xsl:text> </xsl:text> </xsl:for-each> from sub seems to answer your request. note that not only do you not need to update a variable, you don't need a variable at all.
