Re: [xsl] XPath which tests that an element does not have mixed content?

With xpath++ based on xsltproc and EXSLT this can be done similar:

$ xpath++ "normalize-space(str:concat((//author|//person)/text()))!=''"
author.xml
true
$

In XSLT 2.0 you could test the join of text() children of the cited
elements along the lines of:

   not(normalize-space( string-join( (author,Person)/text() ),'')))

I hope this helps.
