Sean, I got Allaire's example working. I found these problems based on the
version I copied from the Allaire website:
1. If you copy the example XSL file from the website, the <xsl:stylesheet>
tag's xmlns:xsl attribute value is broken into 2 lines, causing the xsl
processor to fail completely. Instead of doing the transformation, it was
just outputting the content of the original xsl file. The namespace needs
to be in a continuous line, as follows:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
2. The printWriter class wasn't being closed, so the file containing the
wddx was never being flushed to disk. I added the following to the end of
the code:
<cfset printWriter.close()>
3. The resulting processed file wasn't being read into a CF variable, so I
added:
<cffile action="read"
file="[path]wddx_test.wddx"
variable="wddx">
4. Next, when I tried to run <cfwddx> to transform the wddx to a structure,
I got:
Error Diagnostic Information
unknown exception condition
TagCFWddx::execute
There was an error in the XSL file: the "item" element was being mapped to a
named structure; since it was a structure within an array, it couldn't take
a name, causing the WDDX parser to fail. I corrected the XSL file, and
everything now works. Here's my corrected XSL file:
************************
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<!-- Match invoice root & emit WDDX packet wrapper -->
<xsl:template match="/invoice">
<wddxPacket version="1.0">
<header/>
<data>
<struct>
<xsl:apply-templates/>
</struct>
</data>
</wddxPacket>
</xsl:template>
<!-- Process all elements that map to array variables -->
<xsl:template match="billableHours">
<var name="{name(.)}">
<array length="{count(*)}">
<xsl:apply-templates/>
</array>
</var>
</xsl:template>
<!-- Process all elements that map to struct variables -->
<xsl:template match="invoice|contractorInfo|address">
<var name="{name(.)}">
<struct>
<xsl:apply-templates/>
</struct>
</var>
</xsl:template>
<!-- Process structures inside arrays (no names) -->
<xsl:template match="item">
<struct>
<xsl:apply-templates/>
</struct>
</xsl:template>
<!-- Process all elements that map to string variables -->
<xsl:template
match="firstName|lastName|street|city|state|zip|country|voice|fax|email|
description|currency">
<var name="{name(.)}">
<string>
<xsl:value-of select="text()"/>
</string>
</var>
</xsl:template>
<!-- Process all elements that map to number variables -->
<xsl:template match="invoiceID|employeeID|hours|amount">
<var name="{name(.)}">
<number>
<xsl:value-of select="text()"/>
</number>
</var>
</xsl:template>
<!-- Process all elements that map to date-time variables -->
<xsl:template match="dateSubmitted|date">
<var name="{name(.)}">
<string>
<xsl:value-of select="text()"/>
</string>
</var>
</xsl:template>
</xsl:stylesheet>
************************
I'll pass this info to the folks at Allaire.
