Looking For Text Of An Element Or Source Of Current Page

I am doing the following in selenium 2/webdrive using python and firefox... I am opening some web pages that I need to check for a specific string - which, if present, means it is

Solution 1:

If you don't know which exception to expect, use empty except and traceback:

import traceback

try:
    int('string')
except:
    traceback.print_exc()
    print "returning 0"

# will print out an exception and execute everything in the 'except' clause:
# Traceback (most recent call last):
#   File "<stdin>", line 2, in <module>
# ValueError: invalid literal for int() with base 10: 'string'
# returning 0

But from the stack trace you already do know the exact exception name, so use it instead:

from selenium.webdriver.exceptions import NoSuchElementException

try:
    #...
except NoSuchElementException, err:
    #...

---

UPDATE:

You just get an exception before the try ... except, here:

product_block = browser.find_element_by_xpath("//div[@class='page_content']");

and not here:

product_name = product_block.find_element_by_xpath("//h2[@class='page_title']");

Solution 2:

That's the solution! Thanks!

Here is the final code, cleaned up a bit to make the result more readable:

    #!/usr/bin/env python

from selenium import webdriver
from selenium.webdriver import Firefox as Browser
from selenium.webdriver.support.ui import WebDriverWait

browser = webdriver.Firefox()

def call_productpage(productlink):
    global browser

    print 'in call_productpage(' + productlink + ')'
    browser.get(productlink)
    browser.implicitly_wait(1)
    product_block = ''
    try:
        product_block = browser.find_element_by_xpath("//div[@class='page_content']");
    except:
        print 'this is NOT a good page - drop it'
        return 0
    else:
        textStr = str(product_block.text)
        #print 'page_content:' + str(textStr)
        print '\nthis is a good page - proceed\n'

    print 'made it past the exception!\n'

    product_name = product_block.find_element_by_xpath("//h2[@class='page_title']");
    nameStr = str(product_name.text)
    print '>>> product_name:' + nameStr + '\n'
    print "test over!"
    return 1

test1 = call_productpage('https://www.daz3d.com/i/3d-models/-/desk-clocks?spmeta=ov&item=12657')
print '\nTest #1:\n============\n'
if test1:
    print '\ntest 1 returned true\n'
else:
    print '\ntest 1 returned false\n'

print '\nTest #2:\n============\n'
test2 = call_productpage('https://www.daz3d.com/i/3d-models/-/dierdre-character-pack?spmeta=ov&item=397')
if test2:
    print '\ntest 2 returned true\n'
else:
    print '\ntest 2 returned false\n'
print '\n============\n'

And that works just as I need it to.

Again, thanks.
