This is a somewhat backwards approach to web scraping. I need to locate the xpath of a web element AFTER I have already found it with a text()= identifier
Because the xpath values are different based on what information shows up, I need to use predictable labels inside the row for locating the span text next to found element. I found a simple and reliable way is locating the keyword label and then increasing td integer by one inside the xpath.
def x_label(self, contains):
mls_data_xpath = f"//span[text()='{contains}']"
string = self.driver.find_element_by_xpath(mls_data_xpath).get_attribute("xpath")
digits = string.split("td[")[1]
num = int(re.findall(r'(\d )', digits)[0]) 1
labeled_data = f'{string.split("td[")[0]}td[{num}]/span'
print(labeled_data)
labeled_text = self.driver.find_element_by_xpath(labeled_data).text
return labeled_text
I cannot find too much information on .get_attribute() and get_property() so I am hoping there is something like .get_attribute("xpath") but I haven't been able to find it.
Basically, I am taking in a string like "ApprxTotalLivArea" which I can rely on and then increasing the integer after td[0] by 1 to find the span data from cell next door. I am hoping there is something like a get_attributes("xpath") to locate the xpath string from the element I locate through my text()='{contains}' search.

The Remote WebElement does includes the following methods:
But xpath
isn't a valid property of a WebElement. So get_attribute("xpath")
will always return NULL

I was able to find a python version of the execute script from this post that was based off a JavaScript answer in another forum. I had to make a lot of .replace() calls on the string this function creates but I was able to universally find the label string I need and increment the td/span xpath by 1 to find the column data and retrieve it regardless of differences in xpath values on different page listings.
