Selenium Python 2 find element by name and value?
提问by user3883665
I have been trying to locate an element on a web page, this element has the same name as other elements and no id. It does have a different value, so I would like to find the element by the name AND the Value.
我一直试图在网页上定位一个元素，该元素与其他元素同名且没有 id。它确实有一个不同的值，所以我想通过名称和值来查找元素。
in my web page I have a search button:
在我的网页中，我有一个搜索按钮：
<input name="action" value=" Search " style=" border-style2; font-size: 11;
font-family: arial, helvetica" border="0" type="submit">
I can't use name because I have another element with the same name and type:
我不能使用 name，因为我有另一个具有相同名称和类型的元素：
<input name="action" value=" Go " onclick=" return custRange('cust', 'd_custno');"
style=" border-style2; font-size: 11; font-family: arial, helvetica"
border="0" type="submit">
I therefore tried to use xpath, I started by using the xpath checker to return the xpath which returned:
因此，我尝试使用 xpath，我首先使用 xpath 检查器返回返回的 xpath：
/x:html/x:body/x:center/x:table/x:tbody/x:tr/x:td/x:center/x:center[1]/x:table[2]/x:tbody/x:tr/x:td[1]/x:table[3]/x:tbody/x:tr[5]/x:td[2]/x:input[2]
Again pretty new to this but I'm assuming the "x:" shouldn't be in the path so I removed this and tried to find the element with the following:
再次对此很新，但我假设“x：”不应该在路径中，所以我删除了它并尝试找到具有以下内容的元素：
search = driver.find_element_by_xpath("//center[1]/table[2]/tbody/tr/td[1]/table[3]/tbody/tr[5]/td[2]/input[2]")
search.clickAndWait()
which resulted in:
这导致：
selenium.common.exceptions.NoSuchElementException: Message: 'Unable to find element with xpath == //center[1]/table[2]/tbody/tr/td[1]/table[3]/tbody/tr[5]/td[2]/input[2]'
So really I have 2 questions it would be great if someone could help with:
所以我真的有两个问题，如果有人可以提供帮助，那就太好了：
- is there a way to identify an element by name and value?
- obviously I'm missing something with xpath, is the way I'm trying to use xpath incorrect? if so could you suggest what I'm doing wrong?
- 有没有办法通过名称和值来识别元素？
- 显然我在 xpath 中遗漏了一些东西，我尝试使用 xpath 的方式不正确吗？如果是的话，你能建议我做错什么吗？
Any help greatly appreciated.
非常感谢任何帮助。
for completeness my unittest code is is as follows:
为了完整起见，我的单元测试代码如下：
import unittest
from selenium import webdriver
from selenium.webdriver.common.keys import Keys
class umLoginTest(unittest.TestCase):
def setUp(self):
self.driver = webdriver.Ie()
self.driver.implicitly_wait(3)
def test_login_to_um(self):
driver = self.driver
result_file = open("umLoginTest_result.txt", "w")
driver.get("http://ps-iweb/UserManage/Home")
self.assertIn("Welcome", driver.title)
elem = driver.find_element_by_name("userLogin")
elem.send_keys("pstevenson")
password = driver.find_element_by_name("sec_password")
password.send_keys("etc")
password.send_keys(Keys.RETURN)
test1 = driver.title
result_file.write(str(test1))
select = driver.find_element_by_name("conn_marketid")
for option in select.find_elements_by_tag_name('option'):
if option.text == 'Int Rate Swaps':
option.click()
search = driver.find_element_by_xpath("//center[1]/table[2]/tbody/tr/td[1]/table[3]/tbody/tr[5]/td[2]/input[2]")
search.clickAndWait()
result_file.close()
if __name__ == "__main__":
unittest.main()

Answering your questions,
回答你的问题，
1 - Yes you can,
1 - 是的，你可以，
driver.find_element_by_name(‘foo')
2 - I always try to avoid xpath because sometimes it doesn't work properly. Instead, you should always try to find by name or id .. I think is the best case.
2 - 我总是尽量避免使用 xpath，因为有时它无法正常工作。相反，您应该始终尝试按名称或 ID 查找 .. 我认为这是最好的情况。

Following is the Java code, which i tried with your 2 controls specified above.
以下是 Java 代码，我尝试使用上面指定的 2 个控件。
driver= new FirefoxDriver();
driver.get("file:///D:/Programming%20Samples/Input.html");
driver.findElement(By.xpath("//*[@name='action'][@value='Go']")).click();
driver.findElement(By.xpath("//*[@name='action'][@value='Search']")).click(); //observed here in your HTML i see some spaces. Make sure giving the right value.
Hope above helps.
以上希望有所帮助。
