Pattern	Matches	Example
*	any element	*
tag	elements with the given tag name	div
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^=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 2 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. div:not(:has(div)) finds divs that do not contain divs.
: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.
	The above may be combined in any order and with other selectors	.light:contains(name):eq(0)
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 an+b-1 siblings before it in the document tree, for any positive integer or zero value of n, and has a parent element. For values of a and b greater than zero, this effectively divides the element's children into groups of a elements (the last group taking the remainder), and selecting the bth element of each group. For example, this allows the selectors to address every other row in a table, and could be used to alternate the color of paragraph text in a cycle of four. The a and b values must be integers (positive, negative, or zero). The index of the first child of an element is 1. In addition to this, :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
