evaluateItem
Evaluate the function- Specified by:
evaluateItem
in interfaceExpression
- Overrides:
evaluateItem
in classComputedExpression
- Parameters:
c
- The context in which the expression is to be evaluated- Returns:
- the node or atomic value that results from evaluating the expression; or null to indicate that the result is an empty sequence
- Throws:
XPathException
- if any dynamic error occurs evaluating the expression
-
iriToUri
Escape special characters in a URI. The characters that are %HH-encoded are all non-ASCII characters- Parameters:
s
- the URI to be escaped- Returns:
- the %HH-encoded string
-
escape
