Subject: RE: [xsl] how to evaluate a dyna generated variable? From: "Michael Kay" <mhk@xxxxxxxxx> Date: Mon, 8 Sep 2003 10:48:25 +0100 |
This isn't a good way to tackle this requirement. exsl:evaluate() does say that all the variables are accessible, but you might find implementations that aren't conformant with this; it's a heavy overhead for processor to have to maintain so much context at run-time. Better to do it in pure XSLT. Rather than declaring several variables with semantics hidden in the choice of variable names, use the power of XML to declare a composite (tree-structured) variable, and access it's components using path expressions. Unfortunately you will also need the node-set extension. <xsl:variable name="participants"> <p nr="1">Absolute Relation</p> <p nr="2">Relative Relation</p> </xsl:variable> <xsl:value-of select="xx:node-set($participants)/p[@nr=$type]"/> Michael Kay > -----Original Message----- > From: owner-xsl-list@xxxxxxxxxxxxxxxxxxxxxx > [mailto:owner-xsl-list@xxxxxxxxxxxxxxxxxxxxxx] On Behalf Of Cao Hui > Sent: 08 September 2003 09:35 > To: XSL-List@xxxxxxxxxxxxxxxxxxxxxx > Subject: [xsl] how to evaluate a dyna generated variable? > > > Hello, > I have defined the I18n resources with variables like this: > <xsl:variable name="lang.type.participant.1" > select="'Absolute Relation'"/> <xsl:variable > name="lang.type.participant.2" select="'Relative Relation'"/> > <xsl:variable name="lang.type.participant.3" select="'Group > Expression'"/> > > and in my stylesheet, I want to get the resource like this: > <xsl:value-of > select="exsl:evaluate(concat('$lang.type.participant.',Type))"> > but it seems exsl:evaluate only accept variables that contain > XPath reference,right? then is there any way to do this? > > Thanks > Max Cao > > > > > _________________________________________________________ > Do You Yahoo!? > 启用电邮帐号,领会雅虎通[身临其境聊电影]的动感魅力,还有网络摄像头+雅 虎通收音机等你来拿 > http://cn.rd.yahoo.com/mail_cn/tag/?http://cn.messenger.yahoo.com > > XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list > XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
