Subject: [xsl] how to do the expression and count function correctly? From: "Zoe Peng" <zoe@xxxxxxxxxxxx> Date: Tue, 18 Jun 2002 16:29:02 -0400 |
Hi, Please help about the expression and count function. if item_service exist, I want to display item_service_svc_id; otherwise, I want to display the item_id. Results I want: Top Stories: 7009 News: 3.2 the problem I am facing is: It always displays item_id(3.1, 3.2) cuz $nService is always grate than 1 in this case. what should I do?? any function I can use?? Thanks. --Zoe <!-- xml document --> <?xml version="1.0"?> <tm_user_device_menu statuscode="0" statusdesc="OK"> <user_device usr_id="user1" /> <menu> <item item_id="3.1" item_title="Top Stories" > <item_service item_service_type="default" item_service_svc_id="1000" item_service_usr_svc_nam="Top Stories" /> </item> <item item_id="3.2" item_title="News" > <item item_id="3.2.1" item_title="US" > <item_service item_service_type="default" item_service_svc_id="1001" item_service_usr_svc_nam="US" /> </item> <item item_id="3.2.2" item_title="Americas" item_dsc="America" item_image_path="/images/news.gif"> <item_service item_service_type="default" item_service_svc_id="1002" item_service_usr_svc_nam="Americas" /> </item> </item> </menu> </tm_user_device_menu> <!-- stylesheet --> <xsl:variable name="nService"> <xsl:value-of select="count (tm_user_device_menu/menu/item/item_service)" /> </xsl:variable> <xsl:for-each select="tm_user_device_menu/menu/item"> <xsl:variable name="iId"> <xsl:value-of select="./@item_id" /> </xsl:variable> <xsl:variable name="sId"> <xsl:value-of select="./item_service/@item_service_svc_id" /> </xsl:variable> <xsl:variable name="sNam"> <xsl:value-of select="./item_service/@item_service_usr_svc_nam" /> </xsl:variable> <anchor><xsl:value-of select="./@item_title" /> <xsl:choose> <xsl:when test="$nService = 0"> <go href="/menu{$url.sessionId}?MNUITEMID={$iId}" /> </xsl:when> <xsl:otherwise > <go href="/service{$url.sessionId}?SID={$sId}&USRSVCNAM={$sNam}" /> </xsl:otherwise> </xsl:choose> </anchor> <br/> </xsl:for-each> XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
