Python/Selenium - find element by xpath - element there, but not found

Question

I have a website with the following items:

<input type="text" style="width:230px;" name="email"></input>

and

<input type="password" style="width:230px;" name="password"></input>

With the following python code trying to set values (know username and password are set earlier in code):

Helper.getElementByxPath(mydriver,'//*[@name="email"]',username);
Helper.getElementByxPath(mydriver,'//*[@type="password"]',password);

And Helper.getElementByxPath is defined as:

def getElementByxPath(mydriver,xPath,valueString):
    try:
        a = mydriver.find_element_by_xpath(xPath);
        a.send_keys(valueString);
        return 1;
    except:
        return 0;

I get the following errors:

Unexpected error: <class 'selenium.common.exceptions.NoSuchElementException'>
Unexpected error: <class 'selenium.common.exceptions.NoSuchElementException'>

What am I possibly doing wrong here? Banging my head against a wall.

I am an idiot, my desired form was embedded in a frame. Within a frame.

Answer 1

If your elements are in a frame , you can use

driver.switch_to_frame(IDENTIFIER)

IDENTIFIER can be
- Frame name
- Frame webelement
- Frame index

API reference here: http://selenium-python.readthedocs.org/en/latest/api.html

Once you're finished in the frame, you can return to the top of the document as follows:

driver.switch_to_default_content()
