Hi David,

I'm glad I do learn useful stuff now and then and I probably never ran into
the issue as we don't put comments in our data.  But I certainly agree that
programming fault tolerant is the smartest option.  So from now on I will
avoid using text().

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.
