xml - How to determine if there is text at a node with xpath/schematron -

i'm looking way write xpath/schematron test identify specific node time contains sort of non-white space, unwrapped text anywhere directly within node (meaning possibly among, not in child element). if xml looks this:

<root> ...  <node>      <arbitrarychild/>      find me      <arbitrarychild>don't find me</arbitrarychild>      more text  </node>  ...  <node>      <arbitrarychild/> <arbitrarychild/>      <arbitrarychild>don't find me</arbitrarychild>  </somenode> ... </node>     

it identify first instance of somenode, not second. i've tried every variation of contains(...), text(), , test="..." can think of, i'm approaching wrong direction.

i think it's simply

node[text()[normalize-space()]]

i don't think "and *" in answer @har07 relates requirement stated in question: didn't there had @ least 1 element child, there had (non-empty) text.
