No, a white-space-only node is a ***text*** node, not an element,
consisting of any combination of the following characters: space
(&#x20;), tab (&#9;), newline (&#10;) and carriage return (&#13;).

If by "elements which have some text in it" you mean to have a
text-node child, then use the following:

myel[text()]

In case you need an element some of the descendents of which are text
nodes (not necessarily its immediate children), the following XPath
expression might be evaluated more efficiently:

myel[descendant::text()]

The XPath expression contained in your message:

myel[not(string-length(.) = 0)]

will also work in this case, but it requires that the concatenation of
all text node descendents be constructed (probably some intelligent
XPath engine will not do this?).
