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().

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.
