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.
$ 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. :-)
