E:link¶

An "E" element being the source anchor of a hyperlink of which the target is not yet visited (":link") or already visited (":visited"). Note that Mojo::DOM::CSS is not stateful, therefore ":any-link", ":link" and ":visited" yield exactly the same results.

  my $links = $css->select(':any-link');
  my $links = $css->select(':link');
  my $links = $css->select(':visited');

E:visited¶

  my $foo = $css->select('div#foo');

E:not(s1, s2)¶

An "E" element that does not match either compound selector "s1" or compound selector "s2". Note that support for compound selectors is EXPERIMENTAL and might change without warning!

  my $others = $css->select('div p:not(:first-child, :last-child)');

Support for compound selectors was added as part of Selectors Level 4 <https://dev.w3.org/csswg/selectors-4>, which is still a work in progress.

E:is(s1, s2)¶

An "E" element that matches compound selector "s1" and/or compound selector "s2". Note that this selector is EXPERIMENTAL and might change without warning!

  my $headers = $css->select(':is(section, article, aside, nav) h1');

This selector is part of Selectors Level 4 <https://dev.w3.org/csswg/selectors-4>, which is still a work in progress.

E:has(rs1, rs2)¶

An "E" element, if either of the relative selectors "rs1" or "rs2", when evaluated with "E" as the :scope elements, match an element. Note that this selector is EXPERIMENTAL and might change without warning!

  my $link = $css->select('a:has(> img)');

This selector is part of Selectors Level 4 <https://dev.w3.org/csswg/selectors-4>, which is still a work in progress. Also be aware that this feature is currently marked "at-risk", so there is a high chance that it will get removed completely.

E:text(string_or_regex)¶

An "E" element containing text content that substring matches "string_or_regex" case-insensitively or that regex matches "string_or_regex". For regular expressions use the format ":text(/.../)". Note that this selector is EXPERIMENTAL and might change without warning!

  # Substring match
  my $login = $css->select(':text(Log in)');
  # Regex match
  my $login = $css->select(':text(/Log ?in/)');
  # Regex match (case-insensitive)
  my $login = $css->select(':text(/(?i:Log ?in)/)');

This is a custom selector for Mojo::DOM and not part of any spec.

A|E¶

An "E" element that belongs to the namespace alias "A" from CSS Namespaces Module Level 3 <https://www.w3.org/TR/css-namespaces-3/>. Key/value pairs passed to selector methods are used to declare namespace aliases.

  my $elem = $css->select('lq|elem', lq => 'http://example.com/q-markup');

Using an empty alias searches for an element that belongs to no namespace.

  my $div = $c->select('|div');

E F¶

An "F" element descendant of an "E" element.

  my $headlines = $css->select('div h1');

E > F¶

An "F" element child of an "E" element.

  my $headlines = $css->select('html > body > div > h1');

E + F¶

An "F" element immediately preceded by an "E" element.

  my $second = $css->select('h1 + h2');

E ~ F¶

An "F" element preceded by an "E" element.

  my $second = $css->select('h1 ~ h2');

E, F, G¶

Elements of type "E", "F" and "G".

  my $headlines = $css->select('h1, h2, h3');

E[foo=bar][bar=baz]¶

An "E" element whose attributes match all following attribute selectors.

  my $links = $css->select('a[foo^=b][foo$=ar]');

tree¶

  my $tree = $css->tree;
  $css     = $css->tree(['root']);

Document Object Model. Note that this structure should only be used very carefully since it is very dynamic.

matches¶

  my $bool = $css->matches('head > title');
  my $bool = $css->matches('svg|line', svg => 'http://www.w3.org/2000/svg');

Check if first node in "tree" matches the CSS selector. Trailing key/value pairs can be used to declare xml namespace aliases.

select¶

  my $results = $css->select('head > title');
  my $results = $css->select('svg|line', svg => 'http://www.w3.org/2000/svg');

Run CSS selector against "tree". Trailing key/value pairs can be used to declare xml namespace aliases.

select_one¶

  my $result = $css->select_one('head > title');
  my $result =
    $css->select_one('svg|line', svg => 'http://www.w3.org/2000/svg');

Run CSS selector against "tree" and stop as soon as the first node matched. Trailing key/value pairs can be used to declare xml namespace aliases.
