parsel 1.9.0

1.9.0 (2024-03-14)

• Now requires cssselect >= 1.2.0 (this minimum version was required since 1.8.0 but that wasn’t properly recorded)

• Removed support for Python 3.7

• Added support for Python 3.12 and PyPy 3.10

• Fixed an exception when calling __str__ or __repr__` on some JSON selectors

• Code formatted with black

• CI fixes and improvements

1.8.1 (2023-04-18)

• Remove a Sphinx reference from NEWS to fix the PyPI description

• Add a twine check CI check to detect such problems

1.8.0 (2023-04-18)

• Add support for JMESPath: you can now create a selector for a JSON document and call Selector.jmespath(). See the documentation for more information and examples.

• Selectors can now be constructed from bytes (using the body and encoding arguments) instead of str (using the text argument), so that there is no internal conversion from str to bytes and the memory usage is lower.

• Typing improvements

• The pkg_resources module (which was absent from the requirements) is no longer used

• Documentation build fixes

• New requirements:

  • jmespath

  • typing_extensions (on Python 3.7)

1.7.0 (2022-11-01)

• Add PEP 561-style type information

• Support for Python 2.7, 3.5 and 3.6 is removed

• Support for Python 3.9-3.11 is added

• Very large documents (with deep nesting or long tag content) can now be parsed, and Selector now takes a new argument huge_tree to disable this

• Support for new features of cssselect 1.2.0 is added

• The Selector.remove() and SelectorList.remove() methods are deprecated and replaced with the new Selector.drop() and SelectorList.drop() methods which don’t delete text after the dropped elements when used in the HTML mode.

1.6.0 (2020-05-07)

• Python 3.4 is no longer supported

• New Selector.remove() and SelectorList.remove() methods to remove selected elements from the parsed document tree

• Improvements to error reporting, test coverage and documentation, and code cleanup

1.5.2 (2019-08-09)

• Selector.remove_namespaces received a significant performance improvement

• The value of data within the printable representation of a selector (repr(selector)) now ends in ... when truncated, to make the truncation obvious.

• Minor documentation improvements.

1.5.1 (2018-10-25)

• has-class XPath function handles newlines and other separators in class names properly;

• fixed parsing of HTML documents with null bytes;

• documentation improvements;

• Python 3.7 tests are run on CI; other test improvements.

1.5.0 (2018-07-04)

• New Selector.attrib and SelectorList.attrib properties which make it easier to get attributes of HTML elements.

• CSS selectors became faster: compilation results are cached (LRU cache is used for css2xpath), so there is less overhead when the same CSS expression is used several times.

• .get() and .getall() selector methods are documented and recommended over .extract_first() and .extract().

• Various documentation tweaks and improvements.

One more change is that .extract() and .extract_first() methods are now implemented using .get() and .getall(), not the other way around, and instead of calling Selector.extract all other methods now call Selector.get internally. It can be backwards incompatible in case of custom Selector subclasses which override Selector.extract without doing the same for Selector.get. If you have such Selector subclass, make sure get method is also overridden. For example, this:

class MySelector(parsel.Selector):
    def extract(self):
        return super().extract() + " foo"

should be changed to this:

class MySelector(parsel.Selector):
    def get(self):
        return super().get() + " foo"
    extract = get

1.4.0 (2018-02-08)

• Selector and SelectorList can’t be pickled because pickling/unpickling doesn’t work for lxml.html.HtmlElement; parsel now raises TypeError explicitly instead of allowing pickle to silently produce wrong output. This is technically backwards-incompatible if you’re using Python < 3.6.

1.3.1 (2017-12-28)

• Fix artifact uploads to pypi.

1.3.0 (2017-12-28)

• has-class XPath extension function;

• parsel.xpathfuncs.set_xpathfunc is a simplified way to register XPath extensions;

• Selector.remove_namespaces now removes namespace declarations;

• Python 3.3 support is dropped;

• make htmlview command for easier Parsel docs development.

• CI: PyPy installation is fixed; parsel now runs tests for PyPy3 as well.

1.2.0 (2017-05-17)

• Add SelectorList.get and SelectorList.getall methods as aliases for SelectorList.extract_first and SelectorList.extract respectively

• Add default value parameter to SelectorList.re_first method

• Add Selector.re_first method

• Add replace_entities argument on .re() and .re_first() to turn off replacing of character entity references

• Bug fix: detect None result from lxml parsing and fallback with an empty document

• Rearrange XML/HTML examples in the selectors usage docs

• Travis CI:

  • Test against Python 3.6

  • Test against PyPy using “Portable PyPy for Linux” distribution
