Subject: [xsl] How to Use Current Node Value to Test to See if Option Should be Selected From: "Andrew Kerns" <akerns@xxxxxxxxxxxx> Date: Tue, 12 Mar 2002 16:31:37 -0500 |
I have a menu and a list of items that a user has chosen. I want to display the form and test each menu item to see if it is in the chosen_list. If it is I want to set the option to selected. I can not figure out how to use the current node value to build a expression to test to see if the value was in the chosen list of not. Right now the code below assigns the literal string I want to execute to the variable $chosen-item. The variable query never gets evaulated and so $chosen-item always evalutates to true and so everything is set to selected. Any ideas. Thanks. —- XML File —- <SIMPLE_MENU> <CHOSEN_LIST> <CHOSEN_ITEM>Mexico</CHOSEN_ITEM> </CHOSEN_LIST> <MENU> <MENU_ITEM>Canada</MENU_ITEM> <MENU_ITEM>Mexico</MENU_ITEM> <MENU_ITEM>United States</MENU_ITEM> </MENU> </SIMPLE_MENU> —-XSL Style sheet —- <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="html"/> <xsl:template match="/"> <HTML> <BODY> <CENTER/> <FORM METHOD="POST" NAME="MENU" ACTION="ReportBuilder.ASP" > <xsl:element name="SELECT"> <xsl:attribute name="NAME">VARIABLE</xsl:attribute> <xsl:attribute name="MULTIPLE"/> <xsl:attribute name="SIZE">3</xsl:attribute> <xsl:apply-templates select="//MENU/MENU_ITEM" /> </xsl:element> <p/> <input type="submit" name="btnSelect" value="Select"/> <input type="button" name="btnCancel" value="Cancel" onClick="window.location.href='ReportBuilder.asp'"/> </FORM> </BODY> </HTML> </xsl:template> <xsl:template match="MENU/MENU_ITEM"> <xsl:variable name="chosen-item"> select="//CHOSEN_LIST/CHOSEN_ITEM/text()='.'" </xsl:variable> <xsl:value-of select = "$chosen-item" /> <xsl:element name="OPTION"> <xsl:if test="$chosen-item"> <xsl:attribute name="SELECTED">selected</xsl:attribute> </xsl:if> <xsl:value-of select ="." /> </xsl:element> </xsl:template> </xsl:stylesheet> XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
