In XPath 1.0 you're stuck, just as you feared.
Just had an idea -- finite string-join approximations.
Simulate
string-join(text(),'')
by
concat(text()[1],text()[2],...,text()[k])
for any finite chosen value k.
This works in XPath 1.0 given that k is chosen big enough.
Sample:
$ xpath++ "concat(/a/text()[1],/a/text()[2],/a/text()[3])" mixed.xml 13
$
Yes but I think it will fail if /a has only one text node child, since
concat() will only have one argument in that case. (OTOH you now know
not to trust my error-prone wetware XPath processor.)
You could try concat('','',/a/text()[1],/a/text()[2],/a/text()[3]) to
make sure there are always at least two arguments.
But I'd rather not have the problem to begin with. :-)
