Selenium web driver getting the text from the for attribute of a label using Ruby

Question

I have seen some examples of how to do this in Javascript or python, but am looking for how to find the text of the for attribute on a label. e.g.

<label for="thisIsTheTextNeeded">LabelText</label> 
<input type="checkbox" id=thisIsTheTextNeeded">

We want to pick up the text from the for attribute on the label element. Then use that text as the id to find the checkbox.

The .NET solution might look like:

textWeNeed = selenium.getAttribute("//label[text()='LabelText']/@for");

I tried this in Ruby:

textWeNeed =
@browser.find_element("xpath//label[text()='LabelText']/@for")

and get the error:

expected "xpath//label[text()=input_value]/@for":String to respond to #shift (ArgumentError)

Any ideas?

Here is how I fixed it. Thanks for all the help!

element = @browser.find_element(:xpath=>"//label[text()=\'#{input_value}\']")
attrValue = element.attribute('for') listElement =
@browser.find_element(:id=>"#{attrValue}")

You should use the attribute method to get the value of the attribute. See the doc

element = @browser.find_element(:xpath, "//label[text()='LabelText']")
attrValue = element.attribute("for")

According to OP's comment and provided html I think the element needs some explicit wait

wait = Selenium::WebDriver::Wait.new(:timeout => 10) # seconds

element = wait.until { @browser.find_element(:xpath => "//label[contains(text(),'My list name')]") }
attrValue = element.attribute("for")

I think I am closer, but not quite there. Thanks. – Laura Hannah Vachon Apr 07 '15 at 20:58
@LauraHannahVachon I see **Typo** in in xpath. It should be **LabelText** not *LaelText* correct? – Saifur Apr 07 '15 at 21:01
The given selector //label[text()="LabelText"] is either invalid or does not result in a WebElement. The following error occurred: InvalidSelectorError: Unable to locate an element with the xpath expression //label[text()="LabelText"] because of the following error: [Exception... "The expression is not a legal expression." code: "12" nsresult: "0x805b0033 (SyntaxError)" location: ""] (Selenium::WebDriver::Error::InvalidSelectorError) – Laura Hannah Vachon Apr 07 '15 at 21:04
Can you provide the actual html of the element? – Saifur Apr 07 '15 at 21:06
element = @browser.find_element(:xpath, "//label[text()=#{input_value}]") attrValue = element.attribute("for") listCheckboxPtr = @browser.find_element(:id, attrValue) – Laura Hannah Vachon Apr 07 '15 at 21:09

Is that the label you want ? – Saifur Apr 07 '15 at 21:11
Yes, I need to find that label and get the text of the for. Then use that ID to find a checkbox with the id – Laura Hannah Vachon Apr 07 '15 at 21:12

find_element function requires Hash to search with xpath.

correct way is here,

textWeNeed =
@browser.find_element(xpath: "xpath//label[text()='LabelText']/@for")

below is wrong way(your code).

textWeNeed =
@browser.find_element("xpath//label[text()='LabelText']/@for")

I found in Ruby when looking for Strings best to use is :find: instead of :find_element:

textWeNeed = @browser.find("xpath//label[text()='LabelText']/@for")

when presented with the error: "String to respond to #shift"
