The last one there isn't even well-formed XML. I think that you want to follow the same pattern as the previous two, and use: <set target="/psd/layer[@name='Blue']/@top" value="0.0" /> don't you? > PS, Why the @name and @visibility and @opacity. What does the @ > represent? In XPath, '@' is a shorthand for specifying the attribute axis. For example: psd/layer would give you the 'layer' child *element* of psd, whereas: psd/@layer would give you the 'layer' *attribute* of psd. By the way, what application are you using these XPaths in? It doesn't look like it's XSLT...
