1382 node-set id(object)
1383The id function selects elements by their unique ID
1384(see [5.2.1 Unique IDs]). When the argument to id is of type node-set,
1385then the result is the union of the result of applying id to the
1386string value of each of the nodes in the argument node-set. When the
1387argument to id is of any other type, the argument is converted to a
1388string as if by a call to the string function; the string is split
1389into a whitespace-separated list of tokens (whitespace is any sequence
1390of characters matching the production S); the result is a node-set
1391containing the elements in the same document as the context node that
1392have a unique ID equal to any of the tokens in the list.</p><p>

1431he string function converts an object to a string as follows:
1432 - A node-set is converted to a string by returning the value of

1434 If the node-set is empty, an empty string is returned.
1435 - A number is converted to a string as follows
1436 + NaN is converted to the string NaN
1437 + positive zero is converted to the string 0
1438 + negative zero is converted to the string 0
1439 + positive infinity is converted to the string Infinity
1440 + negative infinity is converted to the string -Infinity
1441 + if the number is an integer, the number is represented in
1442 decimal form as a Number with no decimal point and no leading
1443 zeros, preceded by a minus sign (-) if the number is negative
1444 + otherwise, the number is represented in decimal form as a
1445 Number including a decimal point with at least one digit
1446 before the decimal point and at least one digit after the
1447 decimal point, preceded by a minus sign (-) if the number
1448 is negative; there must be no leading zeros before the decimal
1449 point apart possibly from the one required digit immediately
1450 before the decimal point; beyond the one required digit
1451 after the decimal point there must be as many, but only as
1452 many, more digits as are needed to uniquely distinguish the
1453 number from all other IEEE 754 numeric values.
1454 - The boolean false value is converted to the string false.
1455 The boolean true value is converted to the string true.

1512 string substring(string, number, number?)
1513The substring function returns the substring of the first argument
1514starting at the position specified in the second argument with
1515length specified in the third argument. For example,
1516substring(&quot;12345&quot;,2,3) returns &quot;234&quot;. If the third argument is not
1517specified, it returns the substring starting at the position specified
1518in the second argument and continuing to the end of the string. For
1519example, substring(&quot;12345&quot;,2) returns &quot;2345&quot;. More precisely, each
1520character in the string (see [3.6 Strings]) is considered to have a
1521numeric position: the position of the first character is 1, the position
1522of the second character is 2 and so on. The returned substring contains
1523those characters for which the position of the character is greater than
1524or equal to the second argument and, if the third argument is specified,
1525less than the sum of the second and third arguments; the comparisons
1526and addition used for the above follow the standard IEEE 754 rules. Thus:
1527 - substring(&quot;12345&quot;, 1.5, 2.6) returns &quot;234&quot;
1528 - substring(&quot;12345&quot;, 0, 3) returns &quot;12&quot;
1529 - substring(&quot;12345&quot;, 0 div 0, 3) returns &quot;&quot;
1530 - substring(&quot;12345&quot;, 1, 0 div 0) returns &quot;&quot;
1531 - substring(&quot;12345&quot;, -42, 1 div 0) returns &quot;12345&quot;
1532 - substring(&quot;12345&quot;, -1 div 0, 1 div 0) returns &quot;&quot;</p><p>
