cssselect-1.6.0 (Python module)

[Bruce Dubbs]

New minor version.

[Joe Locash]

Version 1.6.0
-------------

Released on 2026-10-09.

*   Dropped support for Python 3.10.

*   Added support for Python 3.15.

*   **Backward-incompatible change**: ``Relation``, which represents
    ``:has()``, now takes and exposes a list of ``(combinator, selector)``
    pairs as ``arguments``, replacing its ``combinator`` and ``subselector``
    arguments and attributes.

*   **Backward-incompatible change**: the
    ``GenericTranslator.xpath_relation_*_combinator()`` methods now take only
    the XPath expression of the ``:has()`` argument and return an XPath
    condition string. Translator subclasses that override them need to be
    updated.

*   ``:has()`` now supports any relative selector list, e.g.
    ``:has(> a.important, + p b)``, where it used to support a single
    argument made only of type, class and universal selectors.

*   ``:not()`` now supports a complex selector argument, e.g.
    ``:not(a.important[rel] > b)``.

*   Added support for the ``i`` and ``s`` attribute selector flags, e.g.
    ``[href^="HTTP" i]``, for ASCII case-insensitive and case-sensitive value
    matching.

*   ``*|element`` and ``[*|attrib]`` now match elements and attributes in any
    namespace, including none. They used to match only those with no
    namespace, like ``|element`` still does and the newly supported
    ``[|attrib]`` does.

    ``Element.namespace`` and ``Attrib.namespace`` are now ``"*"`` for the
    namespace wildcard.

*   Aligned the ``:enabled`` and ``:disabled`` pseudo-classes of
    ``HTMLTranslator`` with the HTML Living Standard:

    * ``input`` elements with no ``type`` attribute or with
      ``type="hidden"`` can now be ``:enabled`` and ``:disabled``.

    * Links (``a``, ``area`` and ``link`` with ``href``) are no longer
      ``:enabled``.

    * Form controls inside the first ``legend`` of a disabled ``fieldset`` are
      no longer ``:disabled``.

    * ``option`` elements inside a disabled ``optgroup`` are now
      ``:disabled``.

    * ``command`` elements are no longer ``:enabled`` or ``:disabled``, and
      ``keygen`` elements are no longer ``:enabled``.

*   Null and surrogate code points, both raw and escaped (e.g. ``\0``), are
    now replaced with U+FFFD, as the CSS specification requires. Raw null
    code points used to cause a ``SelectorSyntaxError``, and the others used
    to end up in the generated XPath.

*   The descendant combinator now translates into a ``descendant::`` step, e.g.
    ``e f`` into ``e/descendant::f`` instead of ``e/descendant-or-self::*/f``,
    which lxml evaluates faster.

*   Class selectors and the ``~=`` attribute operator now translate into an
    XPath expression that starts with a plain ``contains()`` check, which lxml
    evaluates faster on most documents.

*   Documented the support for ID selectors whose value is not a valid CSS
    identifier, e.g. ``#37signals``, as a non-standard extension.
