Question

我有一个表可以在这里找到：Ontario Gov Employee Directory我正在尝试遍历表来提取数据，但是很难找到xpath才能这样做。

当我检查我看到的元素时，表没有id：

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

如何遍历这些行中的数据？

Answer 1

它是表格中的一个表格，然后有一些非常标准的格式。你有什么挑战？

当我检查我看到的元素时，表格没有id：

它可以使用其他属性，例如标题。使用xpath //table[@title="results_list"]/tbody/tr/td查找最里面的表中的每个数据元素。或者从xpath中删除最后一个/td以获取每一行。之后，找到其下的每个td元素并使用其text。

注意：最里面的表有第一列带有序列号，第二列带有实际数据。我建议让每个td然后使用＆＃39; innerHTML＆＃39;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

使用selenium webdriver循环通过表
