Reference

Returns true if unparsed-text() would succeed for the given URI and encoding, allowing safe guarded file reads.

Reads a text file from a URI and returns its lines as a sequence of strings, one item per line.

Reads a plain text file from a URI and returns its contents as an xs:string, with optional encoding specification.

Converts every character of a string to its Unicode uppercase equivalent using locale-independent Unicode case mapping.

Returns a sequence of xs:anyURI values from a named collection, giving the URIs of the contained documents.

Declares a streaming accumulator that maintains a typed value updated by rules as nodes are processed, enabling stateful aggregation without multiple passes.

Defines when and how an xsl:accumulator's value is updated, matching nodes by pattern and firing at the start or end of matched elements.

Processes a string against a regular expression, separating matching and non-matching substrings for independent handling.

Selects a set of nodes and applies the best-matching template rule to each one, enabling recursive tree processing.

Creates an XDM array from xsl:array-member children, providing ordered positional access to sequences of arbitrary XDM values in XSLT 3.0.
