I get it now. (I was getting confused between the namespace `DAV:` and the namespace `DAV`, duh!) Is it compulsory to register a namespace prefix? I can seem to find no way of using a fully qualified XPath. For a namespace `NS` calling `registerNs(NS, NS)` works. Is that the only way?	[reply]

If you want to use a prefix in xpath, a prefix that doesn't occur in the xml, you have to register it You don't have to use a prefix in xpath, just write longer xpath `//*[ local-name() != 'propfind' and contains(local-name(), 'prop') and namespace-uri() = 'DAV:' ]` [download] It all works the same Read more...

`$xpc->registerNS($prefix, $ns)` defines a prefix. (Not the only one, though.) You can't use a prefix you haven't defined. But it's possible to build XPaths that don't use prefixes using `namespace-uri()` and `local-name()`.	[reply] [d/l] [select]
