Re: expression value not a node set on content match

I should probably have made that first contains() function look more like
contains(text(),'21 '). With contains(.,'21 '), you're testing the
string-value of the entire 'record' element, which is going to be the
concatenation of all its descendant text nodes, including the ones that
are children of the sub-elements. You really only want to test the text
node child(ren) of the 'record' element. The same might apply for the
sub-element if there is a risk of more elements below.

In my code I go to the trouble of specifying text() instead of . more
often than not, to avoid any potential ambiguities like this.
