You probably mean ' or ' here rather than '|'. With that change, the two look the same to me though the second will probably run faster. Could be wrong though, I did not spend much time on it. preceding-sibling::p[last()] is also the same as ../p (the first p child of this node's parent) is that what you meant? Its handy to know that XPath expressions (and XML attributes in general) can have white space in them, including newlines.
