Xslt2

A cast or constructor function received a value it cannot convert — casting text to a number or date is the usual suspect. Guard with 'castable as' or use number().

The pattern given to matches(), replace(), tokenize() or xsl:analyze-string is not a valid XPath regular expression — watch out for curly braces in attributes and unsupported constructs.

A type error: an expression returned a sequence or type that does not match what the function, operator or comparison expects. The strict type rules of XPath 2.0+ are usually behind it.

Two xsl:result-document instructions resolved to the same output URI — usually a static href inside a loop. Make the href dynamic.

How to use xsl:result-document in XSLT 2.0 and 3.0 to produce multiple output files from a single stylesheet. Covers split by category, multi-format output, serialization control, and streaming.

Returns a deep copy of all nodes in the sequence, detached from the original document.

Returns true if two sequences are deeply equal: same items in the same order with equal node identity or atomic values.

Raises a dynamic error with an optional error code, description message, and error object.

Asserts that the sequence contains exactly one item; raises a dynamic error if the sequence has zero or more than one item.

Returns the local part of an xs:QName value as an xs:NCName.
