>Implement the <GTKDOCLINK

node-set id(object)
The id function selects elements by their unique ID
(see [5.2.1 Unique IDs]). When the argument to id is of type node-set,
then the result is the union of the result of applying id to the
string value of each of the nodes in the argument node-set. When the
argument to id is of any other type, the argument is converted to a
string as if by a call to the string function; the string is split
into a whitespace-separated list of tokens (whitespace is any sequence
of characters matching the production S); the result is a node-set
containing the elements in the same document as the context node that
have a unique ID equal to any of the tokens in the list.</P

string string(object?)
he string function converts an object to a string as follows:
- A node-set is converted to a string by returning the value of
the node in the node-set that is first in document order.
If the node-set is empty, an empty string is returned.
- A number is converted to a string as follows
+ NaN is converted to the string NaN
+ positive zero is converted to the string 0
+ negative zero is converted to the string 0
+ positive infinity is converted to the string Infinity
+ negative infinity is converted to the string -Infinity
+ if the number is an integer, the number is represented in
decimal form as a Number with no decimal point and no leading
zeros, preceded by a minus sign (-) if the number is negative
+ otherwise, the number is represented in decimal form as a
Number including a decimal point with at least one digit
before the decimal point and at least one digit after the
decimal point, preceded by a minus sign (-) if the number
is negative; there must be no leading zeros before the decimal
point apart possibly from the one required digit immediatelyi
before the decimal point; beyond the one required digit
after the decimal point there must be as many, but only as
many, more digits as are needed to uniquely distinguish the
number from all other IEEE 754 numeric values.
- The boolean false value is converted to the string false.
The boolean true value is converted to the string true.</P

&lt;=, &lt;, &gt;=, &gt;, then the objects are compared by converted both objects
to numbers and comparing the numbers according to IEEE 754. The &lt;
comparison will be true if and only if the first number is less than the
second number. The &lt;= comparison will be true if and only if the first

>Implement the <GTKDOCLINK
HREF="SUBSTRING"

>() XPath function
string substring(string, number, number?)
The substring function returns the substring of the first argument
starting at the position specified in the second argument with
length specified in the third argument. For example,
substring("12345",2,3) returns "234". If the third argument is not
specified, it returns the substring starting at the position specified
in the second argument and continuing to the end of the string. For
example, substring("12345",2) returns "2345". More precisely, each
character in the string (see [3.6 Strings]) is considered to have a
numeric position: the position of the first character is 1, the position
of the second character is 2 and so on. The returned substring contains
those characters for which the position of the character is greater than
or equal to the second argument and, if the third argument is specified,
less than the sum of the second and third arguments; the comparisons
and addition used for the above follow the standard IEEE 754 rules. Thus:
- substring("12345", 1.5, 2.6) returns "234"
- substring("12345", 0, 3) returns "12"
- substring("12345", 0 div 0, 3) returns ""
- substring("12345", 1, 0 div 0) returns ""
- substring("12345", -42, 1 div 0) returns "12345"
- substring("12345", -1 div 0, 1 div 0) returns ""</P
