Find Elements¶
Find Methods¶
Splinter’s browser provides 8 methods for finding elements.
Example¶
Given the following HTML:
<input type="button" id="btn_13" name="clickMeBtn" value="Click Me!">Do it!</input>
The following methods will find the element:
from splinter import Browser
browser = Browser()
elems = browser.find_by_css('#btn_13')
elems = browser.find_by_xpath("//input[@id='btn_13']")
elems = browser.find_by_tag('input')
elems = browser.find_by_name('clickMeBtn')
elems = browser.find_by_text('Do it!')
elems = browser.find_by_id('btn_13')
elems = browser.find_by_value('Click Me!')
elems = browser.find('clickMeBtn')
Each of these methods returns an ElementList with all matching elements.
browser.find()¶
Unlike the other finder methods, browser.find()
does not specify the strategy used.
By default, it searches for an element by name.
This can be can changed to css or xpath using the browser.set_find_strategy()
method.
from splinter import Browser
browser = Browser()
browser.set_find_strategy('css')
elems = browser.find('#btn_13')
This will stay in effect for the entire life cycle of your script, unless explicitly changed again.
Although browser.find()
has a less explicit naming structure, it’s also less verbose.
If the majority of your selectors use the same strategy it can improve the readability of your script.
Find Within Elements¶
Elements implement the same finder methods as the browser. The only difference being the root of the find operation. Only child elements of the root element will be searched for.
from splinter import Browser
browser = Browser()
all_divs = browser.find_by_tag("div")
child_elements = all_divs.first.find_by_css(".item")
Find Links¶
To target only links on a page, the links
namespace provides 4 find methods.
This is available at both the browser and element level.
Example¶
Given the following HTML:
<div class="main">
<a href="http://example.com">Link for Example.com</a>
</div>
The following methods will find the element:
from splinter import Browser
browser = Browser()
links_found = browser.links.find_by_text('Link for Example.com')
links_found = browser.links.find_by_partial_text('for Example')
links_found = browser.links.find_by_href('http://example.com')
links_found = browser.links.find_by_partial_href('example')
elem = browser.find_by_css('.main').first
links_found = my_element.links.find_by_text('Link for Example.com')
links_found = my_element.links.find_by_partial_text('for Example.com')
links_found = my_element.links.find_by_href('http://example.com')
links_found = my_element.links.find_by_partial_href('example')
As the other find_*
methods, these return an ElementList.
ElementList¶
These objects are functionally similar to Python’s list object, but with a few differences:
Get the first found element with the first
attribute:
first_found = browser.find('clickMeBtn').first
Get the last found element with last
attribute:
last_found = browser.find('clickMeBtn').last
Get by index:
second_found = browser.find('clickMeBtn')[1]
Handling Empty Lists¶
If an element is not found, the element finding methods return an empty ElementList.
If you try to access items in this list, a
splinter.exceptions.ElementDoesNotExist
exception will be raised.

class.
