RE: [xsl] regarding strip-space

Hi,

It's text node, that contains only white space characters, i.e. space characters, carriage returns, line feeds, and tabs. The thingy you're describing above is just an element, that happens to have no children.

here you have to make a difference between elements that are non-empty and elements that have text nodes as children. The predicate above will ignore e.g.

<myel><foo /></myel>

So if you need to test whether myel is an empty node, use

//myel[not(node())]

but if you want to test if myel has any text node children, you need test

//myel[not(text())]
