Returns an XPath expression that identifies a node.
path() ➔ xs:string
There are no arguments
path($node as node()) ➔ xs:string
The node whose path is required
Notes on the Saxon implementation
Available since before Saxon 8.0. This function is dropped in Saxon 11; applications should use the XPath 3.0 fn:path() function in preference.
The first version of the function (with no arguments) is equivalent to supplying
"." as the argument. In this case there must be a context item and it
must be a node.
The function returns a string whose value is an XPath expression identifying the
selected node in the source tree. This can be useful for diagnostics, or to create an
XPointer value, or when generating another stylesheet to process the same document. The
resulting string can be used as input to the
evaluate() function, provided
that any namespace prefixes it uses are declared.
The generated path will use lexical QNames as written in the original source document. In documents that use multiple namespaces, this may not be the most suitable representation if there is a requirement to evaluate the XPath expression later, as any prefixes it uses will need to be declared.
