使用硒webdriver通过表循环

Question

我有一个表，可以在这里找到：Ontario Gov Employee Directory，我试图通过表循环拉出数据，但努力找到xpath能够这样做。

的表没有一个id，当我检查元素我看到：

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

我如何遍历这些行的数据？

Answer 1

这是一个表格内的表格，然后有一些非常标准的格式。你有什么挑战？

的表没有一个id，当我检查元素我看到：

它具有其他属性就可以使用，如标题。使用xpath //table[@title="results_list"]/tbody/tr/td从最里面的表中查找每个数据元素。或者从xpath中删除最后一个/td以获取每一行。之后，找到它下面的每个td元素并使用它的text。

注意：最里面的表格的第一列有序列号，第二列有实际的数据。我建议获取每个td，然后使用'innerHTML'属性或elem.text。之后，使用常规的exppresion来提取不同的部分。

>>> 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
