[Portfolio] parsing template ?

[Noah Botimer]

Hi Jon,

You should check out XsltFunctions.java. It's not all that well  
documented, but there is a method available that turns a reference  
like that into a link, and one that extracts the item's display name.  
It might not be the same as what you'd parse out of this reference,  
but it will be the same as if it were shown in the Resources tool or  
somewhere in the UI (usually the same, though). There are also  
various other methods in there that can be called from your templates.

This technique is actually used in the default Form renderer  
(implemented in formFieldTemplate.xslt). What you're looking for is  
sakaifn:getReferenceUrl() and sakaifn:getReferenceName(), and the  
element with the attachment path is what to pass in. In this snippet,  
that's the current node, so the dot is used. The other stuff here is  
just for enough context to see the default view's attachment list in  
whole.

<!-- if there are attachments already, render these as a list -->
<!--todo: mime type lookup to resolve the icons  -->
<xsl:if test="$currentParent/node()[$name=name()]">
	<ul class="attachList labelindnt" style="clear:both;padding-top:.5em">
		<xsl:for-each select="$currentParent/node()[$name=name()]">
			<li>
				<img>
					<xsl:attribute name="src">
						<xsl:value-of select="sakaifn:getImageUrl(.)" />
					</xsl:attribute>
				</img>
				<input type="hidden" name="{$name}" value="{.}" />
				<a target="_blank">
					<xsl:attribute name="href">
						<xsl:value-of select="sakaifn:getReferenceUrl(.)" />
					</xsl:attribute>
					<xsl:value-of select="sakaifn:getReferenceName(.)" />
				</a>
			</li>
		</xsl:for-each>
	</ul>
</xsl:if>

Cheers,
-Noah
