[xquery-talk] search hit count

[Michael Kay]

You haven't shown a source document, but my guess is that if $entries has
element children called "text", and "classcode", and descendants called
"div1", then the chance of "$entries[.=$keyword]" selecting anything is
quite small, since it is matching on the entire text content of an element
that has children.
