Question

我有一个BeautifulSoup返回的html源代码，使用下面的代码。我已经发布了“ tr”块的样本。我想创建一个字典列表，例如下面的示例“ outputList”，其“ tr”块的“ id”类似于“ ctl00_MainContent_subGBS_DataDetails_ctl01_trGBKItem”。“ _ ctl01”部分更改，其余的id保持不变。 >

我可以使用以下方法将所有具有类似“ id”的“ tr”块放入列表中：

tstsoup.find_all('tr',{'id':re.compile('ctl(\d\d)_MainContent_subGBS_DataDetails_ctl(\d\d)_trGBKItem')})

但是我还没有弄清楚如何挑选出“名称”和“标记”部分。

我刚接触硒和BeautifulSoup。我的最终目标是创建一个脚本，我可以运行该脚本从父母门户中获取孩子的高中成绩。

我一直在此仓库中查看代码：

https://github.com/AlbanyCompSci/aeries-api

代码：

tstsoup = BeautifulSoup(driver.page_source)

所需的输出：

outputList=[{‘name’:’Math 3 Period 1’,’Mark’:’85.10’},{‘name’:’French II’,’Mark’:’93.01’}

tstsoup数据示例：

<tr id="ctl00_MainContent_subGBS_DataDetails_ctl01_trGBKItem">

Answer 1

下面的代码似乎可以解决问题。

代码：

tst_tr=tstsoup.find_all('tr',{'id':re.compile('ctl(\d\d)_MainContent_subGBS_DataDetails_ctl(\d\d)_trGBKItem')})


def grbk(src_tr):

    std_grbk={'name':src_tr.find_all('td')[2].get_text(),
         'Mark':src_tr.find_all('td')[6].get_text()}

    return std_grbk



tst_stuff=[]

for i in range(len(tst_tr)):
    tst_stuff.append(grbk(tst_tr[i]))

从tr标签内部返回元素列表
