Returns the current date.

30 |
31 |
32 |

Signature

33 | 
fn:current-date() as xs:date
34 |
35 |
36 |

Properties

37 |
38 |

This function is deterministic, context-dependent, and focus-independent. It depends on 39 | implicit timezone. 40 | 41 |

42 |
43 |
44 |
45 |

Rules

46 |
47 |

Returns xs:date(fn:current-dateTime()). This is an xs:date 48 | (with timezone) that is current at some time during the evaluation of a query or 49 | transformation in which fn:current-date is executed. 50 |

51 |

This function is deterministic. The precise instant during the query 52 | or transformation represented by the value of fn:current-date is implementation-dependent. 53 |

54 |
55 |
56 |
57 |

Notes

58 |
59 |

The returned date will always have an associated timezone, which will always be the 60 | same 61 | as the implicit timezone in the dynamic context 62 |

63 |
64 |
65 |
66 |

Examples

67 |
68 |

fn:current-date() returns an xs:date corresponding to the 69 | current date. For example, a call of fn:current-date() might return 70 | 2004-05-12+01:00. 71 |

If $arg is the empty sequence, the function returns the empty sequence. 47 |

48 |

Otherwise, the function returns an xs:integer between 1 and 31, both 49 | inclusive, representing the day component in the local value of $arg. 50 |

The expression fn:day-from-dateTime(xs:dateTime("1999-05-31T13:20:00-05:00")) returns 31. 57 |

58 |

The expression fn:day-from-dateTime(xs:dateTime("1999-12-31T20:00:00-05:00")) returns 31. 59 |

60 |

The expression fn:day-from-dateTime(fn:adjust-dateTime-to-timezone(xs:dateTime("1999-12-31T19:20:00-05:00"), 61 | xs:dayTimeDuration("PT0S"))) returns 1. 62 |

53 |
54 |

Notes

55 |
56 |

The default collation property can never be absent. If it is not explicitly defined, 57 | a 58 | system defined default can be invoked. If this is not provided, the Unicode codepoint 59 | collation (http://www.w3.org/2005/xpath-functions/collation/codepoint) is 60 | used. 61 |

Notes

54 |
55 |

The default language property can never be absent. The functions fn:format-integer, 56 | fn:format-date, fn:format-time, and fn:format-dateTime 57 | are defined to use the default language if no explicit language is supplied. The default 58 | language 59 | may play a role in selection of a default collation, but this is not a requirement. 60 |

Signature

35 |

36 |
37 |
38 |

Properties

39 |
40 |

This function is deterministic, context-dependent, and focus-independent. It depends on 41 | available documents, and static base URI. 42 | 43 |

44 |
45 |
46 |
47 |

Rules

48 |
49 |

If $uri is an empty sequence, this function returns false. 50 |

51 |

If a call on fn:doc($uri) would return a document node, this function 52 | returns true. 53 |

54 |

In all other cases this function returns false. This 55 | includes the case where an invalid URI is supplied, and also the case where 56 | a valid relative URI reference is supplied, and cannot be resolved, 57 | for example because the static base URI is absent. 58 |

59 |

If this function returns true, then calling fn:doc($uri) 60 | within the same execution scope must return a document node. However, 61 | if nondeterministic processing has been selected for the fn:doc function, 62 | this guarantee is lost. 63 |

44 |
45 |

The function returns a sequence of strings representing the prefixes of the in-scope 46 | namespaces for $element. 47 |

56 |
57 |
58 |

Notes

59 |
60 |

Under most circumstances, the context size is absent only if the context item is absent. 61 | However, XSLT 3.0 with 62 | streaming defines situations in which the context item and context position are known, 63 | but the context size is unknown. 64 |

Notes

58 |
59 |

XQuery 3.0 and XSLT 3.0 give an implementation freedom to use different base URIs 60 | during 61 | the static analysis phase and the dynamic evaluation phase, that is, for compile-time 62 | and run-time resources respectively. This is appropriate when the implementation allows 63 | the output of static analysis (a "compiled" query or stylesheet) to be deployed for 64 | execution 65 | to a different location from the one where static analysis took place. In this situation, 66 | the 67 | fn:static-base-uri function should return a URI suitable for locating 68 | resources needed during dynamic evaluation. 69 |
