Method Details
-
evaluateItem
Evaluate the function- Specified by:
evaluateItem
in interfaceEvaluableItem
- Overrides:
evaluateItem
in classExpression
- 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
Escape special characters in a URI. The characters that are %HH-encoded are 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
- ASCII characters other than letters and digits that should NOT be %HH-encoded- Returns:
- the %HH-encoded string
-
checkPercentEncoding
Check that any percent-encoding within a URI is well-formed. The method assumes that a percent sign followed by two hex digits represents an octet of the UTF-8 representation of a character; any other percent sign is assumed to represent itself.- Parameters:
uri
- the string to be checked for validity- Throws:
XPathException
- if the string is not validly percent-encoded
