使用硒webdriver通過表循環

Question

我有一個表，可以在這裏找到：Ontario Gov Employee Directory，我試圖通過表循環拉出數據，但努力找到xpath能夠這樣做。

的表沒有一個id，當我檢查元素我看到：

<table title="results_list" border="0" width="100%" cellspacing="0" cellpadding="0">

我如何遍歷這些行的數據？

Answer 1

這是一個表格內的表格，然後有一些非常標準的格式。你有什麼挑戰？

的表沒有一個id，當我檢查元素我看到：

它具有其他屬性就可以使用，如標題。使用xpath //table[@title="results_list"]/tbody/tr/td從最裏面的表中查找每個數據元素。或者從xpath中刪除最後一個/td以獲取每一行。之後，找到它下面的每個td元素並使用它的text。

注意：最裏面的表格的第一列有序列號，第二列有實際的數據。我建議獲取每個td，然後使用'innerHTML'屬性或elem.text。之後，使用常規的exppresion來提取不同的部分。

>>> all_tdata = driver.find_elements_by_xpath('//table[@title="results_list"]/tbody/tr/td') 
>>> for td in all_tdata: 
...  print td.get_attribute('innerHTML') # save this in var and regex it 
...  # or 
...  data = td.text
