How to find parent elements by python webdriver?

Question

Is there any methods for python+selenium to find parent elements, brother elements, or child elements just like

driver.find_element_parent? or
driver.find_element_next? or
driver.find_element_previous?

eg:

<tr>   <td>       <select>         <option value=0, selected='selected'> </option>          <option value=1, > </option>         <option value=2,> </option>      </select>    </td>    <td> 'abcd'      <input name='A'> </input>     <td> <tr> 

I've tried like below, but fail:

input_el=driver.find_element_by_name('A') td_p_input=find_element_by_xpath('ancestor::input') 

How can I get the parent of input element and then, finally, get the option selected?

Answer 1

You can find a parent element by using .. xpath:

input_el = driver.find_element_by_name('A') td_p_input = input_el.find_element_by_xpath('..')

What about making a separate xpath for getting selected option, like this:

selected_option = driver.find_element_by_xpath('//option[@selected="selected"]') 

Answer 2

From your example, I figure you only want the selected option within a table-row if and only if this row also has an input element with the name "A", no matter where in the html-tree this element resides below the row-element.

You can achieve this via the xpath ancestor-axis.

For the sake of better readability I will show how to do this step by step (but you can actually put everything in only one xpath-expression):

# first find your "A" named element namedInput = driver.find_element_by_name("A");          # from there find all ancestors (parents, grandparents,...) that are a table row 'tr' rowElement = namedInput.find_element_by_xpath(".//ancestor::tr");          # from there find the first "selected" tagged option selectedOption = rowElement.find_element_by_xpath(".//option[@selected='selected']");
