I haven't looked at the spec, but this isn't true for libxml2/libxslt/libslax:
(sdb) n
4: var $foo := <top> { <one> "one"; <two> "two"; }
(sdb) n
2: main <foo> { }
(sdb) p $foo
[node-set] (1) rtf-doc
<top>
<one>one</one>
<two>two</two>
</top>
(sdb) p $foo/*
[node-set] (1)
<top>
<one>one</one>
<two>two</two>
</top>
Outside predicates, it's a node test, matching text nodes:
(sdb) p $foo/*/text()
[node-set] (0)
(sdb) p $foo/*/*/text()
[node-set] (2)
one
two
But inside predicates is does return the text, probably like string():
(sdb) p $foo/*/*
[node-set] (2)
<one>one</one>
<two>two</two>
(sdb) p $foo/*[text() == 'one']
[node-set] (0)
(sdb) p $foo/*/*[text() == 'one']
[node-set] (1)
<one>one</one>
It could be just a bug in libxml2; I'll take a look.
Thanks,
Phil
P.s.: the command line I used was:
slaxproc -d -m 'main <foo> { }' -E -m 'var $foo := <top> { <one> "one";
<two> "two"; }'
The ":=" operator turns RTFs into node-sets (via calling node-set()).
