minutes-from-dateTime, minutes-from-time
The two functions
minutes-from-dateTime()
and
minutes-from-time()
extract the minutes component from an
xs:date
or
xs:dateTime
value. For example, at 16:30 local time both these functions return 30.
Signature
| Argument | Type | Meaning |
| input | xs:time or xs:dateTime? | The value from which the minutes component is to be extracted. The type of the supplied argument must correspond to the type implied by the function name. |
| Result | xs:integer | The minutes component, in the range 0 to 59 . |
Effect
The function returns the minutes component of the supplied
xs:time
or
xs:dateTime
. The value is from the time as expressed in its local timezone (which will be the same as the minutes component of the time in UTC except in the case where the timezone offset is not a multiple of one hour).
Examples
| Expression | Result |
| minutes-from-time(xs:time(“12:35:03.142”)) | 35 |
| minutes-from-dateTime(xs:dateTime(“2008-02-28T13:55:30”)) | 55 |
| minutes-from-time(xs:time(“00:30:02+01:00”)) | 30 |
| minutes-from-dateTime(xs:dateTime(“2008-07-31T03:10:00+08:30”)) | 10 |

minutes-from-duration
This function extracts the value of the minutes component from a normalized
xs:duration
value.
Signature
| Argument | Type | Meaning |
| input | xs:duration? | The value from which the component is to be extracted. If an empty sequence is supplied, an empty sequence is returned. |
| Result | xs:integer? | The minutes component, in the range −59 to +59 . |
Effect
The function returns the minutes component of the supplied
xs:duration
. The duration value is first normalized so that the number of hours is less than 24, the number of minutes is less than 60, and so on. The result will be negative if the duration is negative.
Examples
| Expression | Result |
| minutes-from-duration(xs:dayTimeDuration(“PT12H20 M”)) | 20 |
| minutes-from-duration(xs:duration(“PT210 S”)) | 3 |
| minutes-from-duration(xs:duration(“-PT75 M”)) | -15 |
| minutes-from-duration(xs:yearMonthDuration(“P1Y”)) | 0 |

month-from-date, month-from-dateTime
These two functions extract the month component from an
xs:date
or
xs:dateTime
value. For example, on Christmas Day
month-from-date(current-date())
returns 12.
Signature
| Argument | Type | Meaning |
| input | xs:date? or xs:dateTime? | The value whose month component is to be extracted. The type of the supplied argument must correspond to the type implied by the function name. If an empty sequence is supplied, an empty sequence is returned. |
| Result | xs:integer? | The month, in the range 1 (January) to 12 (December) . |
Effect
The function returns the month component of the supplied
xs:date
or
xs:dateTime
. The value is used in its local timezone (not normalized to UTC).
Examples
| Expression | Result |
| month-from-date(xs:date(“2008-02-28”)) | 2 |
| month-from-dateTime(xs:dateTime(“2008-02-28T13:00:00”)) | 2 |
| month-from-date(xs:date(“2008-07-31+01:00”)) | 7 |
| month-from-dateTime(xs:dateTime(“2008-07-31T23:00:00-05:00”)) | 7 |

months-from-duration
This function extracts the value of the months component from a normalized
xs:duration
value.
Signature
| Argument | Type | Meaning |
| input | xs:duration? | The value from which the component is to be extracted. If an empty sequence is supplied, an empty sequence is returned. |
| Result | xs:integer? | The months component, in the range −11 to +11 . |
Effect
The function returns the months component of the supplied
xs:duration
. The duration value is first normalized so that the number of months is less than 12. The result will be negative if the duration is negative.
Examples
| Expression | Result |
| months-from-duration(xs:yearMonthDuration(‘P1Y3 M’)) | 3 |
| months-from-duration(xs:yearMonthDuration(‘P15 M’)) | 3 |
| months-from-duration(xs:duration(‘-P1Y3 M’)) | -3 |
| months-from-duration(xs:dayTimeDuration(‘P365D’)) | 0 |

name
The
name()
function returns a string in the form of a lexical
QName
that represents the name of a node. For example, if the context node is an element namedname()will return the stringms:schema.
Changes in 2.0
Under XPath 2.0 it is an error to supply a sequence containing more than one node, unless running in backward-compatibility mode.
The data model now retains the namespace prefix, so the prefix returned by this function is more predictable.
Signature
| Argument | Type | Meaning |
| node (optional) | node()? | Identifies the node whose name is required. If the argument is an empty sequence, the function returns a zero-length string. If the argument is omitted, the target node is the context node. It is then an error if there is no context item, or if the context item is not a node. |
| Result | xs:string | A string value: a QName representing the name of the target node . |
