I’m trying to make a configuration that allows for convenient building

Or in XML: <clozepassage><p>The quick <clozeword/> jumped over the
<clozeword>…. </p></clozepassage>
I want to have a command button after the <clozepassage> that adds a
<clozeword/> at the end (but inside the <p>), unless the last node is
already a <clozeword/>.
I am just running into a little trouble since I need to select the
/last/ /node that’s a descendant/ of <clozepassage>. Not last child,
which would be the <p>, but the text node that’s “…” in this example.
There might be more structure in the way – it could be multiple
paragraphs, or a list with list items instead of a paragraph, for
instance. I don’t see how to do this with selectNode, or what
alternative methods there might be?
A powerful, XPath 1.0 based, alternative to command "selectNode" is the
<set> descendant element of <macro>:
---
<set
variable = QName
context = XPath expr. returning a node set : "/"
expression = XPath expression
plainString = boolean : false
/>
---
Some variable names are ``mapped'' to the node selection: "selected",
"selected2", "selectedElement", "selectedNode", "selectedNodes".
Example: starting from implicitly selected element, select the closest
ancestor having a "linkend" attribute:
---
<set variable="selectedElement" context="$implicitElement"
expression="(ancestor-or-self::*[@linkend])[last()]" />
---
