Subject: Re: [xsl] how to increment a variable in a for-each loop From: yan bai <bytj@xxxxxxxxx> Date: Wed, 23 Jan 2002 15:14:12 -0800 (PST) |
I have a code snippet as below: <xsl:template match="*" mode="diff_cols"> <xsl:for-each select="."> <xsl:if test="position() mod 2 = 1"> <fo:table-cell background-color="red"> <fo:block><xsl:value-of select="."/></fo:block> </fo:table-cell> </xsl:if> <xsl:if test="position() mod 2 = 0"> <fo:table-cell background-color="blue"> <fo:block><xsl:value-of select="."/></fo:block> </fo:table-cell> </xsl:if> </xsl:for-each> </xsl:template> Unfortunately, it did not work. The background color in all columns is red. Can you help to debug?
