Scraping data inside an iframe with splinter

Question

Currently using splinter and trying to get some data from this page :

• https://ecomm.one-line.com/one-ecom/manage-shipment/cargo-tracking?ctrack-field=CAAU4023030&trakNoParam=CAAU4023030

• Since the data Im looking for is inside the iframe, Im using the get_iframe() according to those docs.

My attempt

iframe = browser.get_iframe('IframeCurrentEcom')

iframe
<contextlib._GeneratorContextManager object at 0x00000210118653A0>

iframe.find_by_xpath("/html/body/div[3]/div[2]/div[1]/form/div[3]/div[1]/div/div/div/div[2]/span[2]")

Output:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: '_GeneratorContextManager' object has no attribute 'find_by_xpath'

I have also tried

>>> with browser.get_iframe('IframeCurrentEcom') as iframe:
...     iframe.find_by_xpath('/html/body/div[3]/div[2]/div[1]/form/div[3]/div[1]/div/div/div/div[2]/span[2]')

Output:

Cannot find element with that id ? Really , here it is a proof that he should be able to find it :

Example (run it on your own)

from splinter import Browser

>>> browser = Browser()
>>> browser.visit("https://www.one-line.com/en")
>>> browser.execute_script("window.scrollTo(0,500)") 
>>> input = browser.find_by_xpath('//*[@id="ctrack-field"]')
>>> input.fill("CAAU4023030")
>>> search = browser.find_by_xpath('/html/body/div[1]/div/main/div[3]/div/div/div/div/div[2]/div/div/div[2]/form/div[2]/button') 
>>> search.click()
>>> browser.get_iframe('IframeCurrentEcom') 
<contextlib._GeneratorContextManager object at 0x000002100F991C40>
>>> iframe = browser.get_iframe('IframeCurrentEcom') 
>>> iframe.html
