XPath selects nodes in an HTML document tree. In Scrapy, write the expression with response.xpath(), then call .get() for one value or .getall() for every match. The most important rules are scope (// versus .//), predicate position (//li[1] versus (//li)[1]), and the difference between text nodes, attributes and an element’s complete string value.
XPath in one minute
The W3C XPath 1.0 Recommendation defines XPath as “a language for addressing parts of an XML document, designed to be used by both XSLT and XPointer” (16 November 1999). HTML scrapers use the same tree-addressing idea after a parser turns the response into elements, text nodes and attributes.
Scrapy’s selector API is a thin wrapper around Parsel, which uses lxml underneath. A Scrapy response can therefore expose both XPath and CSS selection:
title = response.xpath("//title/text()").get()
links = response.xpath("//a/@href").getall().get() returns the first selected result, or None when there is no match (you can provide a default). .getall() always returns a list, including an empty list when nothing matches.

Core XPath cheatsheet
| Goal | XPath | Result and use |
|---|---|---|
| Select every heading | //h1 |
All matching h1 elements. |
| Get heading text nodes | //h1/text() |
Direct text-node children only; nested text needs a descendant query. |
| Read links | //a/@href |
The href attribute from every anchor. |
| Filter an attribute | //a[contains(@href, "image")]/@href |
Anchors whose URL contains the chosen substring. |
| Find an ID | //div[@id="images"] |
Elements with that exact id. |
| First title value | //title/text() |
Use .get() to return one string. |
| All image URLs | //img/@src |
Use .getall() for a list. |
| Descendants of a selected container | .//p |
Paragraphs below the current selector, not elsewhere in the document. |
Understand scope: //, .// and child paths
Document-wide searches
// starts a search from the document root. In a loop over product cards, this is a common mistake:
for card in response.xpath("//article[contains(@class, 'product')]"):
name = card.xpath("//h2/text()").get()The inner //h2 can select headings from the entire document, so every card may receive the same first heading. Use a relative descendant path instead:
for card in response.xpath("//article[contains(@class, 'product')]"):
name = card.xpath(".//h2/text()").get()Relative descendants and direct children
.//p means any paragraph beneath the current node. A bare p selects only direct child paragraphs. Choose the latter when nested cards or footer content must not be included.
Predicates and positional traps
Why //li[1] can return several nodes
Predicates are evaluated in each relevant parent context. //li[1] means the first li child under each parent, so a document with several lists can produce several results. To select the first list item in document order, group the complete result first:

first_item = response.xpath("(//li)[1]").get()Likewise, //div[@class="card"]//a[1] selects the first matching anchor in each card context, while (//div[@class="card"]//a)[1] selects one anchor globally.
Useful predicate forms
//button[@disabled]selects elements that have adisabledattribute, regardless of its value.//input[@type="email"]tests an exact attribute value.//p[position() > 1]skips the first paragraph in each context.//li[last()]gets the last item in each relevant list.//a[contains(., "Next")]/@hreftests the element’s combined text, including nested markup.
Text extraction: nodes versus element values
Direct text and nested text
//h1/text() returns direct text-node children. If markup splits the visible text, such as <h1>Price <em>today</em></h1>, the nested word is not included by that expression. Use .//text() for every descendant text node:
parts = response.xpath("//h1//text()").getall()
heading = " ".join(part.strip() for part in parts if part.strip())Use . for a combined string test
When a string function receives a node-set such as .//text(), XPath 1.0 converts only the first node for that function. Thus contains(.//text(), "Next Page") can fail when “Next Page” is split by a nested element. contains(., "Next Page") checks the element’s string value, including descendant text:
next_url = response.xpath("//a[contains(., 'Next Page')]/@href").get()Use .//text() when you need individual text pieces; use . when testing or extracting the element’s combined textual value.

Classes, IDs and robust matching
Why exact class equality is fragile
Class attributes are space-separated token lists. @class="price" misses class="price sale". A raw contains(@class, "price") can incorrectly match a token such as price-large. Use a token-safe expression:
price_nodes = response.xpath(
"//*[contains(concat(' ', normalize-space(@class), ' '), ' price ')]"
)For ordinary class-based selection, CSS is often clearer, then XPath can handle text, attributes or relationships:
cards = response.css("article.product")
for card in cards:
sku = card.xpath("./@data-sku").get()IDs are usually more stable when the page provides them: //div[@id="images"]. Still inspect the response rather than assuming an ID is unique or permanent.
Relationships that make XPath expressive
- Parent:
//span[@class="label"]/..selects the immediate parent. - Ancestor:
//input[@name="q"]/ancestor::form[1]finds the nearest form. - Following sibling:
//h2[normalize-space()="Specs"]/following-sibling::ul[1]. - Descendant:
//section[@id="content"]//imgfinds images at any depth. - Attribute wildcard:
//div[@*[starts-with(name(), "data-")]]finds elements having adata-attribute.
Prefer a stable anchor (ID, data attribute or meaningful relationship) over a long chain of positional steps that breaks when the layout changes.

Scrapy extraction patterns that avoid silent errors
One value with a fallback
title = response.xpath("normalize-space(//title)").get(default="Untitled")Scrapy’s selector result still needs .get(). For a cleaner text value from an element:
summary = response.xpath("normalize-space(string(//meta[@name='description']/@content))").get(default="")Many values and aligned fields
for row in response.xpath("//table[@id='orders']//tr[position() > 1]"):
yield {
"order": row.xpath("normalize-space(./td[1])").get(),
"status": row.xpath("normalize-space(./td[2])").get(),
}Scope each field to row with ./ or .//; otherwise a document-wide expression can mix data from unrelated rows.
Namespaces, parsers and dynamic pages
Namespaces in XML and feeds
A namespace-free query such as //link may return nothing in a namespaced XML feed. Bind the namespace prefix in the selector API and use that prefix in XPath, or deliberately call Scrapy’s remove_namespaces(). Removing namespaces changes the tree and has a processing cost, so use it only when that trade-off is acceptable.
Choose the response and parser deliberately
XPath syntax is separate from parser behavior. HTML and XML response types can produce different trees, especially around malformed markup. Inspect the actual response body and parsed structure, and use the response type appropriate for the content.

JavaScript-rendered content
XPath can only select nodes present in the parsed response. If a browser creates products after JavaScript runs, the initial Scrapy response will not contain them. Render the page with a suitable browser workflow, then apply XPath to the rendered HTML; changing the expression alone cannot create missing nodes.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.XPath versus CSS in Scrapy
| Need | Usually clearer choice | Reason |
|---|---|---|
| Classes and straightforward structure | CSS | Short, readable selectors; Scrapy translates CSS queries into XPath internally. |
| Text nodes or attributes | XPath | Explicit text(), attribute axes and string functions. |
| Parent, sibling or conditional relationships | XPath | Axes and predicates express relationships directly. |
| Simple descendant selection inside a known container | Either | Choose the style your team can maintain. |
Parsel can be used without Scrapy and relies on lxml. lxml parses HTML and XML but is not included in Python’s standard library.
Troubleshooting checklist
No results
- Print or save the response body and verify the target node exists in the received HTML.
- Check whether the page is JavaScript-rendered and whether the response type handles the markup as expected.
- For XML, check namespaces; bind a prefix or intentionally remove namespaces.
- Confirm attribute spelling, quoting and case.
Too many results
- Replace document-wide
//inside a container loop with.//. - Use parentheses when you mean the first result globally:
(//li)[1]. - Use
.get()only when one value is expected; validate cardinality with.getall()during development.
Wrong or incomplete text
- Replace
text()with.//text()when nested elements split the text. - Use
contains(., "term"), notcontains(.//text(), "term"), for a combined-text condition. - Normalize whitespace with
normalize-space()before storing labels.
Class selector misses cards
Account for multiple class tokens with the token-safe expression, or select the class using CSS and chain a relative XPath.

Practical design rules
- Start with the smallest stable anchor, then add predicates.
- Decide whether the result should be one node or a list before choosing
.get()or.getall(). - Make scope explicit with
./and.//inside loops. - Test against missing, repeated and nested markup, not only the happy-path page.
- Keep parser, namespace and rendering decisions separate from XPath syntax so failures are diagnosable.
Frequently Asked Questions
Can XPath select an HTML attribute directly?
Yes. Use the attribute axis shorthand, such as //a/@href or //img/@src, then call .get() or .getall().
How do I know whether a selector is relative?
A selector beginning with .// or ./ is relative to the current selected node. A selector beginning with // searches from the document context.
Does XPath execute JavaScript?
No. It queries the parsed tree it receives. Render dynamic content first if the target nodes are created by JavaScript.
