python - 当行的 html 标记未嵌套在表头标记下时，在表头下抓取信息行

Question

我正在尝试抓取 table但我遇到了一些障碍。我想确保每个 header 下的数据(例如 Cert Issued (30))与相应的 header 分组。

当我尝试使用下面的 html 时出现问题。

<tr>

标题 (class="EPSBResultHeader") 下方的信息 (class="EPSBResultGridItem" & class="EPSBResultGridAlternatingItem")没有嵌套在它们下面，因此我一直无法找到一种方法来确保每个标题下的信息都与正确的标题分组。

这是我的代码:

count = 0
header = tree.xpath(
    './/table/tr[@class="EPSBResultGridHeader"]')
difference = 10 - len(header)
for i in range(0, difference):
    header.append('')

for license_row in header:
    count = count + 1

    try:
        header_data = license_row.xpath(".//text()")
        header_data = clean(header_data)

        nested_data = license_row.xpath(".//following-sibling::tr//text()")
        nested_data = clean(nested_data)
        print count, header_data
        print count, nested_data

    except AttributeError:
        header_data = ''

    # Append licensure data
    if count == 1:
        lheader1.append(header_data)
        lheader_info1(nested_data)
    if count == 2:
        lheader2.append(header_data)
        lheader_info2(nested_data)
    if count == 3:
        lheader3.append(header_data)
        lheader_info3(nested_data)
    if count == 4:
        lheader4.append(header_data)
        lheader_info4(nested_data)
    if count == 5:
        lheader5.append(header_data)
        lheader_info5(nested_data)

我的最终目标是得到这样的输出:

>>>print lheader_info2
['RANK1', 'Rank I', '07-01-2018', '06-30-2021']

>>>print lheader_info3
['G20', 'Middle School Teaching Field: Social Studies----', 'G30', 'Middle School Teaching Field: English And Communications----', 'ILE2', 'Professional Certificate For Instructional Leadership -- Early Elementary School Principal, Grades K-4; Level II', '07-01-2017', '06-30-2021', 'ILM2', 'Professional Certificate For Instructional Leadership--Middle Grade School Principal, Grades 5-8; Level II', '07-01-2017', '06-30-2021', 'ILV2', 'Professional Certificate For Instructional Leadership--Supervisor Of Instruction, Grades K-12; Level II', '07-01-2018', '06-30-2021', 'PMBF', 'Provisional Certificate For Teaching In The Middle Grades 5-8 (And For Other Assignments As Identified By Kentucky Program Of Studies)', '07-01-2016', '06-30-2021']

我正在使用 lxml 但我也使用了 BeautifulSoup 如果这看起来是更好的方法。

Answer 1

我会找到每个子标题并遍历 next tr siblings一旦遇到另一个 header 或到达表的末尾就打破循环:

from collections import defaultdict
from pprint import pprint

import requests
from bs4 import BeautifulSoup

url = "https://wd.kyepsb.net/EPSB.WebApps/KECI/view_data.aspx?id=37161"
response = requests.get(url)
soup = BeautifulSoup(response.content, "html.parser")

data = defaultdict(list)

table = soup.find("table", class_="EPSBResultGrid")
for header in table.select("tr.EPSBResultGridHeader")[1:]:
    header_name = header.get_text(strip=True)
    for row in header.find_next_siblings("tr"):
        if "EPSBResultGridHeader" in row.get("class", []):
            break

        data[header_name].append(row.td.get_text(strip=True))

pprint(dict(data))

打印:

{'Cert Issued (30)': ['G20', 'G30', 'ILE2', 'ILM2', 'ILV2', 'PMBF'],
 'Do Not Print (00)': ['RANK1'],
 'History (97)': ['ILE2', 'ILM2', 'ILV2', 'RANK1']}

此处的[1:] 切片是为了跳过初始的顶级表头。
