Xpath syntaxe Cheatheet

XPath navigates an XML or HTML document as a tree. Every step has the form axis::node-test[predicate], and most of it has a short form: //div[@class="card"]/a/@href reads “the href of every a inside any div with class card”.

⚠️ Browsers, Selenium and most scrapers implement XPath 1.0. ends-with(), matches(), lower-case() and replace() are 2.0+ and only work in tools like xmllint, Saxon or lxml with an XSLT 2.0 processor. Workarounds for 1.0 are given below.

🧭 Path Syntax

XPath	Selects
`/`	From the document root — an absolute path
`//`	Anywhere in the document, at any depth
`.`	The current (context) node
`..`	The parent of the context node
`@attr`	An attribute
`*`	Any element
`@*`	Any attribute
`text()`	The text nodes of an element
`node()`	Any node at all, text and comments included
`[n]`	The nth match — 1-based, not 0-based
`[last()]`	The last match
`a \| b`	The union of two expressions

/html/body            (: absolute: the body of the page :)
//text()              (: every text node :)
./div/b               (: relative to the context node :)
(//p)[2]              (: the second p in the whole document :)
//p[2]                (: every p that is the second p of its parent :)

🧮 Functions

Strings

Function	Returns
`contains(haystack, needle)`	True when the first string contains the second
`starts-with(haystack, needle)`	True when it starts with it
`concat(s1, s2, …)`	The strings joined together
`normalize-space(s)`	The string with runs of whitespace collapsed and trimmed
`string-length(s)`	The number of characters
`substring(s, start [, length])`	A slice — 1-based
`substring-before(haystack, needle)`	Everything before the first occurrence
`substring-after(haystack, needle)`	Everything after it
`translate(s, from, to)`	Characters mapped one by one — the 1.0 way to fold case

Numbers, logic & nodes

Function	Returns
`count(node-set)`	How many nodes matched
`sum(node-set)`	The sum of their numeric values
`position()`	The index of the context node within its step
`last()`	The size of the context — so `[last()]` is the final node
`name([node-set])`	The qualified name of the first node
`namespace-uri([node-set])`	Its namespace URI
`lang(s)`	True when the node is in that language
`not(expr)`	The negation
`true()` / `false()`	Boolean constants
`boolean(expr)` / `string(o)` / `number(o)`	Type conversions
`ceiling(n)` / `floor(n)` / `round(n)`	Rounding

💡 Case-insensitive matching in XPath 1.0: //E[contains(translate(@A,"ABCDEFGHIJKLMNOPQRSTUVWXYZ","abcdefghijklmnopqrstuvwxyz"), "t")]

🧭 Axes

Axis	Short form	Selects
`child`	(default)	The direct children of the context node
`descendant`	`//`	Every node below the context node
`descendant-or-self`	`//`	The context node and everything below it
`parent`	`..`	The single parent node
`ancestor`	—	Parent, grandparent, up to the root
`ancestor-or-self`	—	The same, including the context node
`following`	—	Everything after the node in document order, except descendants
`following-sibling`	—	Later siblings under the same parent
`preceding`	—	Everything before it, except its ancestors
`preceding-sibling`	—	Earlier siblings under the same parent
`attribute`	`@`	The attributes of the node
`self`	`.`	The context node itself

//td[.="Total"]/ancestor::table          (: the table a cell belongs to :)
//h2[.="Specs"]/following-sibling::ul[1] (: the list after a heading :)
//input[@name="q"]/ancestor-or-self::form (: the form wrapping a field :)

🧠 Worked Examples

//hr[@class="edge" and position()=1]
(: the first hr of class 'edge' under each parent :)

//table[parent::div[@class="pad"] and not(@id)]//a
(: links in unnamed tables inside a padded div :)

/html/body/div/*[preceding-sibling::h4]
(: whatever comes after an h4 :)

//tr/td[font[@class="head" and text()="TRACK"]]
(: cells whose font child says TRACK :)

//*[count(*)=3]
(: elements with exactly three children :)

//rdf:Seq/rdf:li/em:id
(: namespaced elements — the prefixes must be bound by the host tool :)

//var | //acronym
(: a union of two node sets :)

🛠 Running XPath

// browser devtools console
$x('//a[contains(@href, "docs")]');

// plain DOM API
document.evaluate('//h1', document, null, XPathResult.ANY_TYPE, null).iterateNext();

# from the shell, over XML or HTML
xmllint --xpath '//book/title/text()' catalog.xml
xmllint --html --xpath '//a/@href' page.html 2>/dev/null

from lxml import html
tree = html.parse('page.html')
tree.xpath('//div[@class="card"]/a/@href')

# Selenium and Playwright both accept XPath locators
driver.find_element(By.XPATH, '//button[normalize-space()="Save"]')
page.locator('xpath=//button[normalize-space()="Save"]').click()

⚠️ Notes

Indexes start at 1. [0] never matches anything.
//E[1] is per-parent, (//E)[1] is document-wide — the single most common XPath bug.
Namespaced documents need prefixes registered with the host library; in XPath 1.0 a common workaround is //*[local-name()="title"].
// is expensive on large documents; anchor the path when you can.
Prefer text matching with normalize-space() — HTML is full of stray whitespace and line breaks.
