evaluateItem
public Item evaluateItem(XPathContext c)
throws XPathException
- Evaluate the function
- Specified by:
evaluateItem
in interface Expression
- Overrides:
evaluateItem
in class ComputedExpression
- 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

- 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

all non-ASCII characters, plus all ASCII characters except (a) letter A-Z
and a-z, (b) digits 0-9, and (c) characters listed in the allowedPunctuation
argument
- Parameters:
s
- the URI to be escapedallowedPunctuation
