History¶
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
andSelectorList.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
andSelectorList
can’t be pickled because pickling/unpickling doesn’t work forlxml.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
andSelectorList.getall
methods as aliases forSelectorList.extract_first
andSelectorList.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
1.1.0 (2016-11-22)¶
- Change default HTML parser to lxml.html.HTMLParser, which makes easier to use some HTML specific features
- Add css2xpath function to translate CSS to XPath
- Add support for ad-hoc namespaces declarations
- Add support for XPath variables
- Documentation improvements and updates
1.0.3 (2016-07-29)¶
