[FIXED] How to extract all attributes value inside nested android tag or how to extract the value/string inside the attribute by searching on attribute name

Issue

I want to parse the html(or andriod content?) from an mobile app, and i am doing something like

pageSource = driver.page_source
print("page = ",pageSource)

and what i got is the following:

   page =  <?xml version='1.0' encoding='UTF-8' standalone='yes' ?>
<hierarchy index="0" class="hierarchy" rotation="0" width="1080" height="2274">

I want to get all the content of "content-desc"

Updated with full resource get from the webdriver and what i want is the "number" vs the text inside "content-desc".

I have tried

soup = BeautifulSoup(pageSource,"lxml")

with the soup return null

Solution

Since you want all the tags that has an attribute content-desc inside it. You can use regex to do this, as the xml has nested android.view.view tags and content-disc attribute are also present inside other tags in the xml.

Here is how we can do this :

Creating data

page = '''<?xml version='1.0' encoding='UTF-8' standalone='yes' ?>
<hierarchy index="0" class="hierarchy" rotation="0" width="1080" height="2274">

Extracting attribute

import re
soup = BeautifulSoup(page, 'lxml')
for content_disc_element in soup.findAll(re.compile(r".*"), {"content-desc" : re.compile(r".*")}):
    print(content_disc_element['content-desc'])

Output :

This gives us the expected output present for attribute content-desc :
