RSS-Feed with versionLabel of the content

[schneika]

I want to apply the versionLabels of documents to my RSS-Feed.
I use this Freemarker-Template:

Please can you tell me, where is my logical Problem?   :?

[mikeh]

Hi

I think you meant to write child.versionHistory…

Thanks,
Mike

[schneika]

Now with

<versionLabel>Version ${child.versionHistory.versionLabel}</versionLabel> ‍

i get this error:

[mikeh]

Does each document definitely have a version history?

It might be worth wrapping that part with:

<#if hasAspect(child, "cm:versionable") == 1>
…
</#if>‍‍‍

Thanks,

:cry:

[mikeh]

Sorry, my fault. I forgot that versionHistory returns an array, so you have to use something like:

<versionLabel>Version ${child.versionHistory?sort_by("versionLabel")?reverse[0].versionLabel}</versionLabel>
‍‍

to get the most recent version.

Thanks,
Mike

[schneika]

Thanx very much, a very useful tip! now i understand moch more.
But perhaps can you help me once more.
Because now the feed can not be displayed in the browser, i get the Feed-Error:

Nothing obviously wrong after a first look, although it might be easier to see if you could post the XML output that produces the error.

Thanks,
Mike

But the feed cant be displayed either in IE7 nor Firefox 2

[mikeh]

I tried the first three <item>s in that feed and they displayed fine in both MSIE 7 and Firefox 2, so the problem must lie further down the RSS output.

Your best option is to save the full XML into the Tomcat ROOT web app, cut out all the <item> nodes and add them back in one by one, each time refreshing the output in a web browser until you find the problem area.

It's likely to be some string not being encoded as XML, which should be simple to fix.

Thanks,
Mike
