+ Arguments and return type: + + + + + + + + + + + + + + + + + + + + + +
TypeDescription
item()*The first input sequence of items
item()*The second input sequence of items
function(item(), item())The processing function used to process pairs of items from the input + sequences
item()*The resulting sequence after applying the processing function to pairs + of items
+ Examples:
+ + + + + + + + + +
ExpressionResult
for-each-pair((1, 2, 3), ("a", "b"), function($item1, $item2) { + concat($item1, $item2) })Returns a sequence with the concatenated pairs of items: + ("1a", "2b")

+ W3C Documentation reference: for-each-pair
+ + fn:filter($sourceSeq as item()*, $predicate as function(item()) as xs:boolean) as item()* +
+ Filters a sequence of items based on a given predicate function
+ Arguments and return type: + + + + + + + + + + + + + + + + + +
TypeDescription
item()*The input sequence of items
function(item())The predicate function used to filter the items
item()*The resulting sequence after applying the predicate function
+ Examples:
+ + + + + + + + + +
ExpressionResult
filter((1, 2, 3, 4), function($x) { $x mod 2 = 0 })Returns a new sequence containing only the even numbers from the input + sequence: (2, 4)

+ W3C Documentation reference: filter +
+ + + fn:for-each($sourceSeq as item()*, $action as function(item()) as item()*) as item()* +
+ Applies a specified function to each item in a sequence, returning a new + sequence
+ Arguments and return type: + + + + + + + + + + + + + + + + + +
TypeDescription
item()*The input sequence of items
function(item())The function to apply to each item in the sequence
item()*The new sequence created by applying the function to each item in the + input sequence
+ Examples:
+ + + + + + + + + +
ExpressionResult
for-each((1, 2, 3, 4), function($x) { $x * 2 })Returns a new sequence with the result of doubling each number in the + input sequence: (2, 4, 6, 8)
