Selenium Python遍历在第一行停止的行表 [英] Selenium Python iterate over a table of rows it is stopping at the first row

问题描述

我正在使用Selenium Python遍历行表.在GUI上，我已从表中删除了一个项目.在我的脚本中，我正在检查该项目是否不存在，以确认它已被删除. 当我遍历我的桌子时，它停在第一行.直到最后一行才继续.

I am iterating over a table of rows using Selenium Python. On the GUI i have deleted an item from a table. In my script I am checking if the item is not there to verify it has been deleted. When i iterate over my table, it stops at the first row. It does not continue until to the last row.

例如我将Name参数传递给我的方法.我想遍历整个表的行，第1列，并检查名称是否不存在.如果名称"不存在，则返回true.

E.g. I am passing in a Name parameter to my method. I would like to iterate the whole table of rows, column 1 and check the Name is not there. Return true if Name is not there.

我的代码段是:

def is_data_objet_deleted(self, name):
    # Params : name : the name of the data object, e.g. Name, Address, Phone, DOB
     try:
        #WebDriverWait(self.driver, 20).until(EC.presence_of_element_located((By.ID, 'data_configuration_data_objects_ct_fields_body')))
        table_id = WebDriverWait(self.driver, 20).until(EC.presence_of_element_located((By.ID, 'data_configuration_data_objects_ct_fields_body')))
        rows = table_id.find_elements(By.TAG_NAME, "tr")
        for row in rows:
            # Get the columns
            col_name = row.find_elements(By.TAG_NAME, "td")[1]  # This is the Checkbox column
            col_name = row.find_elements(By.TAG_NAME, "td")[2]  # This is the Name column
            print "col_name.text = "
            print col_name.text
            if (col_name.text != name):
                return True
            #return False
     except NoSuchElementException, e:
        print "Element not found "
        print e
        self.save_screenshot("data_objects_page_saved_details")
        return False

我的表在第一行停止. 请帮忙 谢谢， 里亚兹

推荐答案

我只会使用

I would just use all():

def is_data_objet_deleted(self, name):
    table = WebDriverWait(self.driver, 20).until(EC.presence_of_element_located((By.ID, 'data_configuration_data_objects_ct_fields_body')))
    rows = table_id.find_elements(By.TAG_NAME, "tr")

    result = all(row.find_elements(By.TAG_NAME, "td")[2].text != name
                 for row in rows)

    # save a screenshot if there was name found
    if not result:
        self.save_screenshot("data_objects_page_saved_details")
    return result

基本上，如果所有名称均不等于name，则返回True；换句话说:如果name不存在，则返回True.

Basically, this would return True if all the names don't equal to name which is in other words: return True if name is not there.

作为旁注，您正在处理NoSuchElementException，但是它永远不会被try块内使用的任何方法抛出-如果找不到与定位符匹配的元素，find_elements()将返回一个空列表.

As a side note, you are handling NoSuchElementException, but it would never be thrown by any method used inside the try block - find_elements() would return an empty list if no elements matching a locator found.
