Subject: [xsl] Something like eval()? and Thanks! From: "McKeever, Marty" <marty.mckeever@xxxxxxxxxxxxxxxxx> Date: Wed, 07 Nov 2001 09:35:05 -0500 |
Thanks to all who offered solutions to my multile match-->single output problem. I have much to ponder over the weekend and am sure i will learn alot. Apparently it was more difficult than i'd hoped, so i dont feel "quite" as dumb for not finding the solution quickly. Now, for an even crazier idea. Is there any way to force a string of the format "$foo" to evaluate into the matching parameter named $foo. I've looked for an extension function that would do this with no luck. Surely something exists. The scenario: XML Input: <a href="foo.htm?custID=$custID">My Account</a> And passing an external parameter for $custID (23456) I can easily search & replace the custID=$custID with the value of the parameter, IF i already know that "custID" is what needs to be matched. What i'm hoping for is a more generic parameter matching system, where my XML might look like: <a href="foo.htm?custID={$custID}">My Account</a> and i could do the following: <xsl:variable name="flagged"> <xsl:if test="contains(@href,'{$')"> <xsl:value-of select="substring-after(substring before(@href,'}'),'{$')"/> </xsl:if> </xsl:variable> to extract the name of my matching variable from the href, then call my replace template with this value evaluated into the matching parameter: <xsl:call-template name="replace"> <xsl:with-param name="inputString" select="@href"> <xsl:with-param name="changeFrom" select="concat('{$',$flagged,'}')"> <xsl:with-param name="changeTo" select="EVAL(concat('$',$flagged))"> </xsl:call-template> Am i crazy for thinking this might work? Or am i clueless and missing the point? Thanks again -- you guys rock! Marty XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
