Xpath

Returns the qualified name (including namespace prefix, if any) of a node as it appears in the source document.

Returns the namespace URI of a node's expanded name, or an empty string if the node has no namespace.

Returns true if an element node is schema-validated and marked as nilled with xsi:nil="true", otherwise returns false.

Returns the name of a node as an xs:QName value, capturing both the namespace URI and the local name.

Strips leading and trailing whitespace from a string and collapses all internal whitespace sequences to a single space character.

Applies Unicode normalization (NFC, NFD, NFKC, NFKD, or FULLY-NORMALIZED) to a string, ensuring a canonical character representation.

Returns true if its boolean argument is false, and false if it is true — the logical negation of a boolean expression.

Converts a string, boolean, or node-set to a number following XPath 1.0 type-conversion rules, returning NaN if the conversion fails.

Parses a well-balanced XML fragment string and returns it as a document node, allowing multiple top-level nodes.

Parses a well-formed XML string and returns it as a new document node, usable like any other loaded XML document.
