Number including a decimal point with at least one digit

decimal point, preceded by a minus sign (-) if the number

many, more digits as are needed to uniquely distinguish the

Implement the <GTKDOCLINK xmlns="http://www.w3.org/TR/xhtml1/transitional" HREF="substring">substring</GTKDOCLINK>() 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><p>

Implement the normalize-<GTKDOCLINK xmlns="http://www.w3.org/TR/xhtml1/transitional" HREF="space">space</GTKDOCLINK>() XPath function
|
||
string normalize-space(string?)
|
||
The normalize-space function returns the argument string with white
|
||
space normalized by stripping leading and trailing whitespace
|
||
and replacing sequences of whitespace characters by a single
|
||
space. Whitespace characters are the same allowed by the S production
|
||
in XML. If the argument is omitted, it defaults to the context
|
||
node converted to a string, in other words the value of the context node.</p><p>

The translate function returns the first argument string with

occurrences of characters in the second argument string replaced

by the character at the corresponding position in the third argument
|

string. For example, translate("bar","abc","ABC") returns the string

BAr. If there is a character in the second argument string with no
|
||
character at a corresponding position in the third argument string
|
||
(because the second argument string is longer than the third argument
|
||
string), then occurrences of that character in the first argument
|

string are removed. For example, translate("--aaa--","abc-","ABC")</p><p>
