Use Python Selenium to get span text
提问by doremi
This should be easy, but I can't get it to work. I'm running a little demo using the Google homepage as a test.
这应该很容易，但我无法让它工作。我正在使用 Google 主页运行一个小演示作为测试。
Here's my script:
这是我的脚本：
from selenium import webdriver
from selenium.common.exceptions import NoSuchElementException
from selenium.webdriver.common.keys import Keys
import time
browser = webdriver.Chrome()
browser.get("http://www.google.com") # Load page
time.sleep(0.2)
#top nav elements
elems = browser.find_elements_by_xpath("//span[contains(@class, 'gbts')]")
for e in elems:
print e.get_attribute('text')
browser.close()
It returns:
它返回：
None
None
None
None
None
None
None
None
None
None
None
So I think it's grabbing the right elements, but perhaps not the right attribute? Not sure. I also tried to print e.text() but that spit out:
所以我认为它抓取了正确的元素，但可能不是正确的属性？没有把握。我也尝试打印 e.text() 但它吐出来了：
Traceback (most recent call last):
File "sample.py", line 14, in <module>
print e.text()
TypeError: 'unicode' object is not callable
Any thoughts?
有什么想法吗？

e.get_attribute('innerHTML') seems to work.

This should do it:
这应该这样做：
from selenium import webdriver
browser = webdriver.Firefox()
browser.get("http://www.google.com")
for elem in browser.find_elements_by_xpath('.//span[@class = "gbts"]'):
print elem.text
textis a property of the WebElementclass, thus it is not callable.
text是WebElement类的属性，因此不可调用。
class WebElement(object):
"""Represents an HTML element.
...
...
@property
def text(self):
"""Gets the text of the element."""
return self._execute(Command.GET_ELEMENT_TEXT)['value']
You have two alternatives to get the third match:
您有两种选择来获得第三场比赛：
# 1. Modify your xpath expression
browser.find_elements_by_xpath('(.//span[@class = "gbts"])[3]')[0].text
# 2. Access it by list index
browser.find_elements_by_xpath('.//span[@class = "gbts"])')[2].text

YES ! Solution was found (I`am using Python) For instanc: webelement is a p tag
是的 ！找到了解决方案（我正在使用 Python）对于 instanc：webelement 是 ap 标签
webelement.text()
from real situation, stacktrace:
从实际情况来看，堆栈跟踪：
print page_box_block.text() TypeError: 'unicode' object is not callable
打印 page_box_block.text() TypeError: 'unicode' 对象不可调用
it expect to be a html in stdout, but not !
它期望是标准输出中的 html，但不是！
sometimes could be a strange string "unicode object is not callable" or some type error solution is very easy:
有时可能是一个奇怪的字符串“unicode object is not callable”或者一些类型错误的解决方案很简单：
print element.get_attribute("innerHTML")
In java get_attribute("innerHTML") and text() are about to "same", if you need plain text from element In Python 2.7 for now text() sometimes fails.
在 java get_attribute("innerHTML") 和 text() 即将“相同”，如果您需要来自元素的纯文本 在 Python 2.7 现在 text() 有时会失败。
