Python Selenium Download Path |WORK|
Anja Tabatabai
An answer from 2020. The following code solves this. A lot of people new to selenium seem to have to get past this step. Install the chromedriver and put it inside a folder on your desktop. Also make sure to put the selenium python project in the same folder as where the chrome driver is located.
I installed the Chrome Beta 104 + the 104 chrome driver.When I start up the script it recognizes that it's a 104 driver but the driver itself searches for the chrome.exe application within the old chrome path:
That looks like it should be working, so my guess is that you are specifying the path to chromedriver in your code and pointing to a place where is isn't. What happens when you use the example code at the top of this topic in a new console?
There's already chromedirever installed, you don't need to upload another one. Also -- selenium will most probably not work on a free account, due to internet restrictions, and we don't recommend using it in a web app.
"and we don't recommend using it in a web app."--Hmm, thanks for the inputs. I'm thinking of deploying my selenium scraping tool with a front end tool so that I can allow my team mates use it. If it's not recommended on a web app, do you have recommendation how can a selenium tool be used by multiple users?
XPath is a language to query XML documents. Usable on both HTML and XML documents, it allows testers to navigate through the XML structure of any document. It consists of a path expression along with some conditions.
Could somebody please point me to an example where Selenium & webdriver is being used with Home Assistant, as my searches have not fared so well?
The other option I was thinking was to run the python app on another VM, outside of Home Assistant, with the values being sent via MQTT. But this feels like a bit of a waste of resources.
If the locator starts with // or multiple opening parenthesis in front of the //, the locator is considered to be an XPath expression. In other words, using //div is equivalent to using explicit xpath://div and ((//div)) is equivalent to using explicit xpath:((//div))
It is possible chain multiple locators together as single locator. Each chained locator must start with locator strategy. Chained locators must be separated with single space, two greater than characters and followed with space. It is also possible mix different locator strategies, example css or xpath. Also a list can also be used to specify multiple locators. This is useful, is some part of locator would match as the locator separator but it should not. Or if there is need to existing WebElement as locator.
Although all locators support chaining, some locator strategies do not abey the chaining. This is because some locator strategies use JavaScript to find elements and JavaScript is executed for the whole browser context and not for the element found be the previous locator. Chaining is supported by locator strategies which are based on Selenium API, like xpath or css, but example chaining is not supported by sizzle or `jquery
This keyword is most often used to input files into upload forms. The keyword does not check file_path is the file or folder available on the machine where tests are executed. If the file_path points at a file and when using Selenium Grid, Selenium will magically, transfer the file from the machine where the tests are executed to the Selenium Grid node where the browser is running. Then Selenium will send the file path, from the nodes file system, to the browser.
Optional ff_profile_dir is the path to the Firefox profile directory if you wish to overwrite the default profile Selenium uses. Notice that prior to SeleniumLibrary 3.0, the library contained its own profile that was used by default. The ff_profile_dir can also be an instance of the selenium.webdriver.FirefoxProfile . As a third option, it is possible to use FirefoxProfile methods and attributes to define the profile using methods and attributes in the same way as with options argument. Example: It is possible to use FirefoxProfile set_preference to define different profile settings. See options argument documentation in below how to handle backslash escaping.
The string format allows defining Selenium options methods or attributes and their arguments in Robot Framework test data. The method and attributes names are case and space sensitive and must match to the Selenium options methods and attributes names. When defining a method, it must be defined in a similar way as in python: method name, opening parenthesis, zero to many arguments and closing parenthesis. If there is a need to define multiple arguments for a single method, arguments must be separated with comma, just like in Python. Example: add_argument(\"--headless\") or add_experimental_option(\"key\", \"value\"). Attributes are defined in a similar way as in Python: attribute name, equal sign, and attribute value. Example, headless=True. Multiple methods and attributes must be separated by a semicolon. Example: add_argument(\"--headless\");add_argument(\"--start-maximized\").
The string format is space friendly. Usually, spaces do not alter the defining methods or attributes. There are two exceptions. In some Robot Framework test data formats, two or more spaces are considered as cell separator and instead of defining a single argument, two or more arguments may be defined. Spaces in string arguments are not removed and are left as is. Example add_argument ( \"--headless\" ) is same as add_argument(\"--headless\"). But add_argument(\" --headless \") is not same same as add_argument ( \"--headless\" ), because spaces inside of quotes are not removed. Please note that if options string contains backslash, example a Windows OS path, the backslash needs escaping both in Robot Framework data and in Python side. This means single backslash must be writen using four backslash characters. Example, Windows path: \"C:\\path\\to\\profile\" must be written as \"C:\\\\\\\\path\\\\\\to\\\\\\\\profile\". Another way to write backslash is use Python raw strings and example write: r\"C:\\\\path\\\\to\\\\profile\".
Optional service_log_path argument defines the name of the file where to write the browser driver logs. If the service_log_path argument contain a marker index, it will be automatically replaced with unique running index preventing files to be overwritten. Indices start's from 1, and how they are represented can be customized using Python's format string syntax.
Using alias to decide, is the new browser opened is new in SeleniumLibrary 4.0. The options and service_log_path are new in SeleniumLibrary 4.0. Support for ff_profile_dir accepting an instance of the selenium.webdriver.FirefoxProfile and support defining FirefoxProfile with methods and attributes are new in SeleniumLibrary 4.0.
path argument specifies the absolute path to a directory where the screenshots should be written to. If the directory does not exist, it will be created. The directory can also be set when importing the library. If it is not configured anywhere, screenshots are saved to the same directory where Robot Framework's log file is written.
If path equals to EMBED (case insensitive) and Capture Page Screenshot or capture Element Screenshot keywords filename argument is not changed from the default value, then the page or element screenshot is embedded as Base64 image to the log.html.
XPath in Selenium is an XML path used for navigation through the HTML structure of the page. It is a syntax or language for finding any element on a web page using XML path expression. XPath can be used for both HTML and XML documents to find the location of any element on a webpage using HTML DOM structure.
Relative Xpath starts from the middle of HTML DOM structure. It starts with double forward slash (//). It can search elements anywhere on the webpage, means no need to write a long xpath and you can start from the middle of HTML DOM structure. Relative Xpath is always preferred as it is not a complete path from the root element.
The XPath text() function is a built-in function of selenium webdriver which is used to locate elements based on text of a web element. It helps to find the exact text elements and it locates the elements within the set of text nodes. The elements to be located should be in string form.
We can use xpath to grab SVG elements with Selenium Webdriver. A SVG element is identified with tagname svg. The svg image has the attributes like width and height attributes.
So, XPath in selenium can help to locate elements for further scraping. It can work with static data and dynamic data. Moreover, unlike to selectors XPath can operate on all levels of DOM structure including parent elements.
I shared all my tactics, such as XPath contains text, sibling, ancestor, child, preceding, descendant, parent, and so on. I hope this article will help you to write smart and non-brittle selenium find by statements in your projects.
This is by far the best tutorial on using xpath. It clearly explains the structure of an xpath expression; it then describes the variety of usage, clearly and with great graphics.
Great work and thanks.

Hi James, to be frank, I do not have any clue when will they move from 1.0 to 2.0 and 3.1. This question should go to Simon Stewart.
I also found a question here: -i-use-xpath-2-0-with-firefox-and-selenium
HI
I like your tutorial.
I am working on a automation i am unable to find xpath. Its there. but when i find its not coming. I have tried all what you have teach here.
i can find html web element, i can find /body and then the third one is macroponent-f51912f4c700201072b211d4d8c26010 . i can find this too. but after that, even i try relative or absolute path, next div it says its not there.
replaced executable_path in constructor in favor of browser_executable_pathwhich should not be used unless you are the edge case (yep, you are) who can't add your custom chrome installation folder to your PATHenvironment variable, or have an army of different browsers/versions and automatic lookup returns the wrong browser
