public class Selector
extends java.lang.Object
A selector is a chain of simple selectors, separated by combinators. Selectors are case insensitive (including against elements, attributes, and attribute values).
The universal selector (*) is implicit when no element selector is supplied (i.e. *.header and .header
is equivalent).
| Pattern | Matches | Example | |
|---|---|---|---|
* | any element | * | |
tag | elements with the given tag name | div | |
*|E | elements of type E in any namespace ns | *|name finds <fb:name> elements | |
ns|E | elements of type E in the namespace ns | fb|name finds <fb:name> elements | |
#id | elements with attribute ID of "id" | div#wrap, #logo | |
.class | elements with a class name of "class" | div.left, .result | |
[attr] | elements with an attribute named "attr" (with any value) | a[href], [title] | |
[^attrPrefix] | elements with an attribute name starting with "attrPrefix". Use to find elements with HTML5 datasets | [^data-], div[^data-] | |
[attr=val] | elements with an attribute named "attr", and value equal to "val" | img[width=500], a[rel=nofollow] | |
[attr="val"] | elements with an attribute named "attr", and value equal to "val" | span[hello="Cleveland"][goodbye="Columbus"], a[rel="nofollow"] | |
[attr^=valPrefix] | elements with an attribute named "attr", and value starting with "valPrefix" | a[href^=http:] | |
[attr$=valSuffix] | elements with an attribute named "attr", and value ending with "valSuffix" | img[src$=.png] | |
[attr*=valContaining] | elements with an attribute named "attr", and value containing "valContaining" | a[href*=/search/] | |
[attr~=regex] | elements with an attribute named "attr", and value matching the regular expression | img[src~=(?i)\\.(png|jpe?g)] | |
| The above may be combined in any order | div.header[title] | ||
Combinators | |||
E F | an F element descended from an E element | div a, .logo h1 | |
E > F | an F direct child of E | ol > li | |
E + F | an F element immediately preceded by sibling E | li + li, div.head + div | |
E ~ F | an F element preceded by sibling E | h1 ~ p | |
E, F, G | all matching elements E, F, or G | a[href], div, h3 | |
Pseudo selectors | |||
:lt(n) | elements whose sibling index is less than n | td:lt(3) finds the first 3 cells of each row | |
:gt(n) | elements whose sibling index is greater than n | td:gt(1) finds cells after skipping the first two | |
:eq(n) | elements whose sibling index is equal to n | td:eq(0) finds the first cell of each row | |
:has(selector) | elements that contains at least one element matching the selector | div:has(p) finds divs that contain p elements | |
:not(selector) | elements that do not match the selector. See also Elements.not(String) | div:not(.logo) finds all divs that do not have the "logo" class.
| |
:contains(text) | elements that contains the specified text. The search is case insensitive. The text may appear in the found element, or any of its descendants. | p:contains(jsoup) finds p elements containing the text "jsoup". | |
:matches(regex) | elements whose text matches the specified regular expression. The text may appear in the found element, or any of its descendants. | td:matches(\\d+) finds table cells containing digits. div:matches((?i)login) finds divs containing the text, case insensitively. | |
:containsOwn(text) | elements that directly contain the specified text. The search is case insensitive. The text must appear in the found element, not any of its descendants. | p:containsOwn(jsoup) finds p elements with own text "jsoup". | |
:matchesOwn(regex) | elements whose own text matches the specified regular expression. The text must appear in the found element, not any of its descendants. | td:matchesOwn(\\d+) finds table cells directly containing digits. div:matchesOwn((?i)login) finds divs containing the text, case insensitively. | |
:containsData(data) | elements that contains the specified data. The contents of script and style elements, and comment nodes (etc) are considered data nodes, not text nodes. The search is case insensitive. The data may appear in the found element, or any of its descendants. | script:contains(jsoup) finds script elements containing the data "jsoup". | |
| The above may be combined in any order and with other selectors | .light:contains(name):eq(0) | ||
:matchText | treats text nodes as elements, and so allows you to match against and select text nodes. Note that using this selector will modify the DOM, so you may want to | p:matchText:firstChild with input <p>One<br />Two</p> will return one PseudoTextElement with text "One". | |
Structural pseudo selectors | |||
:root | The element that is the root of the document. In HTML, this is the html element | :root | |
:nth-child(an+b) | elements that have :nth-child() can take odd and even as arguments instead. odd has the same signification as 2n+1, and even has the same signification as 2n. | tr:nth-child(2n+1) finds every odd row of a table. :nth-child(10n-1) the 9th, 19th, 29th, etc, element. li:nth-child(5) the 5h li | |
:nth-last-child(an+b) | elements that have an+b-1 siblings after it in the document tree. Otherwise like :nth-child() | tr:nth-last-child(-n+2) the last two rows of a table | |
:nth-of-type(an+b) | pseudo-class notation represents an element that has an+b-1 siblings with the same expanded element name before it in the document tree, for any zero or positive integer value of n, and has a parent element | img:nth-of-type(2n+1) | |
:nth-last-of-type(an+b) | pseudo-class notation represents an element that has an+b-1 siblings with the same expanded element name after it in the document tree, for any zero or positive integer value of n, and has a parent element | img:nth-last-of-type(2n+1) | |
:first-child | elements that are the first child of some other element. | div > p:first-child | |
:last-child | elements that are the last child of some other element. | ol > li:last-child | |
:first-of-type | elements that are the first sibling of its type in the list of children of its parent element | dl dt:first-of-type | |
:last-of-type | elements that are the last sibling of its type in the list of children of its parent element | tr > td:last-of-type | |
:only-child | elements that have a parent element and whose parent element hasve no other element children | ||
:only-of-type | an element that has a parent element and whose parent element has no other element children with the same expanded element name | ||
:empty | elements that have no children at all | ||
