I need some help constructing an XPath to detect nodes containing
duplicate string-values. I am currently restricted to XPath 1.0
syntax , so no access to distinct-values() or exslt unfortunately.
I have a document like this: <dict> <key>Key1</key> <value/> <key>Key2</key> <value/> <key>Key3</key> <value/> <key>Key1</key> <value/> </dict> How do I create an XPath 1.0 expression to detect the <key> elements with duplicate string-values? Thanks!
