Subject: how to change variable values ? From: Gero Nickenig <gnickenig@xxxxxx> Date: Wed, 19 Jul 2000 08:21:54 +0200 (MEST) |
hi, i got the following problem: i want to output a xml-document with a xsl-stylesheet. In this output it should, for example, make a line when the week changes. I tried to do this by using variables... ------------- <xsl:variable name="lastweek"> <!-- Need an Initial value to compare later with currentweek--> <xsl:value-of select="Week"/> <!-- Week is a tag from the xml-document --> </xsl:variable> <xsl:for-each select="Data/Block"> <xsl:variable name="currentweek"> <xsl:value-of select="Week"/> </xsl:variable> <xsl:if test="$currentweek > $lastweek"> <!-- Do something when week changes and set the variable lastweek to this week --> <xsl:variable name="lastweek"> <!-- foo ;-) --> <xsl:value-of select="$currentweek"> </xsl:variable> </xsl:if> . . . </xsl:for-each> -------------------------- Obviously, it complains, that the variable lastweek cannot be defined twice. Is there a way to "just change" the variable lastweek (and not to define it again) ?
