How do you find a specific descendent from an element in selenium?

Question

I’m automating the process of filling some forms online. The problem is that there are many individual elements whose children have basically the same ID of the stuff I want to find and fill. So my idea was to first find the parent I needed using Selenium and then go from there.

for range in cards:
  cardID = driver.find_element(By.XPATH, "//a[contains(text(),'{cardis}/')]/ancestor::tr".format(cardis=allCards_NUMBER_List[range]))
  cardREG_PRICE = cardID.find_element(By.XPATH, "input[contains(id(), 'txt_preco_')]")

But when I run this it only said that it can’t find cardREG_PRICE. The ID name is correct, and from what I’ve read the XPATH structure should work. How can I fix this?

Answer 1

Your xpath is incorrect.That’s why it is failing.
Instead of this

cardREG_PRICE = cardID.find_element(By.XPATH, "input[contains(id(), 'txt_preco_')]")

if should be like.

cardREG_PRICE = cardID.find_element(By.XPATH, ".//input[contains(@id, 'txt_preco_')]")

first thing id is an attribute and should pass with @, second thing // denote the node, Third thing . means intermediate child of the parent.
