Question

How can one call a ColdFusion function, passing in attribute values as arguments, inside an XML transform template statement. For example, something like:

<xsl:template match="date">
    <cfoutput>#DateFormat(now(), <xsl:value-of select="@format"/>)#</cfoutput>
</xsl:template>

Such that the following XML:

<date format="mm/dd/yy" />

Would be matched and transformed to the result of DateFormat(now(), "mm/dd/yy")? Is it possible? I am able to do it with static arguments to DateFormat(), cannot figure out how to extract a value from an attribute/node and use it as an argument. Thank you!

Update

Full version of current attempt:

<cfxml variable="xmlData">
    <?xml version="1.0"?>
    <date format="mm/dd/yy" />
</cfxml>

<cfxml variable="stylesheet">
    <?xml version="1.0"?>
    <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:template match="date">
    <cfoutput>#DateFormat(now(), '<xsl:value-of select="@format"/>')#</cfoutput>
    </xsl:template>
    </xsl:stylesheet>
</cfxml>

<cfoutput>#XmlTransform(xmlData, trim(stylesheet))#</cfoutput>

which results in the following error:

    An error occured while Parsing an XML document.

    Element type "x2l:value-of" must be followed by
    either attribute specifications, ">" or "/>".

Okay, here’s what I think you’re trying to do. You can’t parse with XSLT and ColdFusion in one pass. You have to make two passes.

<cfxml variable="xmlData">
    <?xml version="1.0"?>
    <date format="mm/dd/yy" />
</cfxml>

<cfxml variable="stylesheet">

    <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

    <xsl:template match="date">
        #DateFormat(now(), "<xsl:value-of select="@format"/>")#
    </xsl:template>   

    </xsl:stylesheet>  

</cfxml>


<cfset filename = "#createUUID()#.cfm" />
<cffile action="write" file="#getDirectoryFromPath(getCurrentTemplatePath())##filename#" output="#XmlTransform(xmlData, trim(stylesheet))#"/>

<cfinclude template="#filename#"/>
