Hi Peter,
first, please note that the following does not work:
<a href="#{= ui:label(?section) }">
The problem is that attributes (here: href) can only contain {...} expressions
if those expressions cover the whole length of the string. So the following
would work:
<a href='{= fn:concat("#", ui:label(?section))'>
[ fn:concat is a built-in that takes two or more strings and concatenates them
]. The mixed form of expressions inside of attributes might be supported at
some point in the future, but not right now.
Second, ui:label will by default create human-readable labels, and those may
not be well-formed anchor names. Instead, you may want to use
ui:encodeNode(?section), afn:localName(?section) or smf:qname. The afn
namespace is native to Jena, and smf: is native to TopBraid. The ui: prefix is
native to UISPIN. As long as you stay in TopBraid, all of those will work. All
solutions assume that you have defined proper prefixes for all resources.
Cheers,
Holger
