    Class XNamespace

    Represents an XML namespace URI.

    Like XName, namespace instances are cached/interned: two XNamespace objects for the same URI are the same object.

    Three well-known static namespaces are provided: XNamespace.none, XNamespace.xml, and XNamespace.xmlns.

    The toString method returns {uri}, which enables Clark-notation via string concatenation: XNamespace.get(uri) + "localName" evaluates to "{uri}localName".

    const W = XNamespace.get('http://schemas.openxmlformats.org/wordprocessingml/2006/main');
    const wBody = W.getName('body');
    // Clark notation via string concatenation:
    const name = W + 'body'; // '{http://...}body'
    Index

    none: XNamespace = ...

    The empty namespace (no namespace).

    xml: XNamespace = ...

    The http://www.w3.org/XML/1998/namespace namespace (xml prefix).

    xmlns: XNamespace = ...

      Parameters

      • other: XNamespace

        The namespace to compare against.

      Returns boolean

      true if both are the same interned instance.

    • Returns an XName in this namespace with the given local name.

      Parameters

      • localName: string

        The local part of the qualified name.

      Returns XName

      The cached XName instance.
