Wow.
I would have thought that "text()" would return the text, not a sequence of
nodes.
That's really counter intuitive.

actually using text() makes your code more fragile. If the input has any
comments for example:

<page>page <!-- was 2 now changed-->1</page>

page has string value "page 1" so will work as expected if selected with
an xpath of page but page/text() selects a sequence of two text nodes
with values "page " and "1" which will either do the wrong thing, or
generate an error, depending on how its used.
