Hi Daniel, welcome to Our Umbraco.

You were close, but there is a slight syntax error with your XPath.  Try this:

<span><xsl:value-of select="umbraco.library:GetXmlNodeById(data[@alias='postAuthor'])/node/data[@alias='authorName']" /></span>

In your version, you were returning the "node" element, and not the "data[@alias='authorName']" value.

Let us know how you get on.

Cheers, Lee.

Thanks for the reply Lee, I adjusted my XPath as sugguested by your example but again the macro rendered with no error and without the value that should be appearing. I also adjusted the syntax as follows:

<span><xsl:value-of select="umbraco.library:GetXmlNodeById(data[@alias='postAuthor'])/node/@id" /></span>

this returned nothing... Is this normal behaviour or am I completed missing something here?

Cheers, Daniel

I'm asuming that you somehow have a relation on you current post, right? Then you would need to add the $currenPage parameter into you selection I guess?

Otherwise I don't really get how you would fetch the ID without hardcoding it.

So I think your expression should look like this:

<xsl:value-of select="umbraco.library:GetXmlNodeById($currentPage/data[@alias='postAuthor'])/node/@id" />

Here is some additional syntax:

<!-- Loop through each blog post -->
<xsl:for-each select="$currentPage/node [string(data [@alias='umbracoNaviHide']) != '1']">
    <!-- Display the posts author (content picker, on doc type) -->
    <span><xsl:value-of select="umbraco.library:GetXmlNodeById(data[@alias='postAuthor'])/node/data[@alias='authorName']" /></span>
</xsl:for-each>

Doing a value-of on just data[@alias = 'postAuthor'] returns the nodeID of the author node as expected. So I assume this is still an XPath issue?

Cheers, Daniel

Hi Daniel,

Hmmm... I'd take a step back and see what's going on inside the data/values.  Try the following:

<xmp>
    <xsl:copy-of select="data[@alias='postAuthor']" />
</xmp>

... then if that returns a value, then try ...

<xmp>
    <xsl:copy-of select="umbraco.library:GetXmlNodeById(data[@alias='postAuthor'])" />
</xmp>

... to see if that returns the XML from GetXmlNodeById?

Let us know what it returns.  Hopefully, we'll figure this out soon.

(Personally, I think its something to do with Jan's suggestion ... the context of $currentPage?)

Cheers, Lee.

Just had a "DOH!" moment, Chriztian is correct, it's the extra "/node" that is throwing you off!

Thanks for your help, after reading Chriztian's comment I felt like a **** :) Thanks for all your help.
