    Class XSequence<T>

    A LINQ-style sequence wrapper for arrays of XML objects.

    Wraps an array of XNode or XAttribute items and provides chainable query methods (ancestors, descendants, elements, etc.) that mirror the .NET LINQ to XML extension methods.

    const root = XElement.parse('<catalog><book id="1"><title>A</title></book><book id="2"><title>B</title></book></catalog>');
    const titles = xseq(root.elements("book")).elements("title").toArray().map(el => el.value);
    // ["A", "B"]
