I am working with a rather complex stylesheet to split a TEI document into pieces for an epub file, and get the following trace on an error.

Error on line 204 of splitter.xsl:
XPTY0004: A sequence of more than one item is not allowed as the first argument of
generate-id() (<p/>, <p/>)

Looks pretty straightforward to me: generate-id() takes at most a single node as the argument and you've supplied two paragraph element nodes. Sure enough you have generate-id($node) and I suspect you'll find you have two paragraph elements in that variable.

Can you give me a hint on how to interpret this trace, as I do not understand how a

<xsl:call-template name="content.div1"/>

brings me into a template

<xsl:template name="filename.div0fragment">

Your stylesheet doesn't compile standalone because of missing template rules, which indicates to me there are other fragments at play.

Furthermore, the failing template receives two nodes in a variable that I hardly expect to be grouped together. In the source document they are not even siblings.

They don't have to be siblings to have been selected into the group. Any address can create multiple nodes.

The full stylesheet in question is here:

Nope:

So anything could be going on.

Expose your $node variable after you assign it and see where it gets more than one node in it.

I hope this helps.
