如何在td标签中查找文本？

  • 772

我通过beatidulsoup收到此数据

<td class="Value FormTd" id="p_body_fld_c3a5t2r34212155b1f173" z="custom.wgs_широта" zfieldshape="eSingleLine" zfieldtype="eDouble" ztags="координаты">42,831682</td>

如何获得42.831682？这是我的代码片段：

    browser = webdriver.Chrome()
    browser.get(url)
    open_search = browser.find_element(By.NAME, "p$body$ListSearch$listSearchBox")
    open_search.send_keys(bsfull +'\n')                       
    time.sleep(5)
    soup = BeautifulSoup(browser.page_source, "html.parser")
    candidate = soup.find_all(class_='fieldType-eString')
    #print(candidate[9])

    for linkCandidate in candidate[9]:
        #print(linkCandidate)
        print(f"+ Ссылка новой базовой станции: {linkCandidate['href']}\nИмя БС: {bsfull}")
        #with open("output.log", "a") as outfile:
        #    outfile.write("+ New base station link "+linkCandidate['href']+"\nИмя БС:"+bsfull+"\n")
        browser.get(linkCandidate['href'])
        soup = BeautifulSoup(browser.page_source, "html.parser")
        td = soup.find_all("td")
        #print(type(str(td[6])))
        if "УЦН" in str(td[6]):
            ucn = "УЦН"
            print(ucn)
            dataList2.append(ucn)
        else:
            ucn = "-"
            print(ucn)
            dataList2.append(ucn)
        print("Получены данные УЦН базовых станций, для которых нужно заполнить данные:")
        print(dataList2)
        with open("output.log", "a") as outfile:
            outfile.write("+ The UCN data of the base stations has been received, for which the data needs to be filled in\n")
        print(td[39])
        #latitude = soup.find(td[39])
        latitude = td[39].find(class_="Value FormTd").text
        print(latitude)

出现以下错误：

Получены данные УЦН базовых станций, для которых нужно заполнить данные:
['-']
<td class="Value FormTd" id="p_body_fld_c3a5t2r34212155b1f173" z="custom.wgs_широта" zfieldshape="eSingleLine" zfieldtype="eDouble" ztags="координаты">42,831682</td>

    由于html问题的作者没有给出代码示例，我将假设<td>他正在寻找的所有代码都有一个id以p_body_fld_

    根据文档，我们正在寻找<td>与这些相关的所有内容id

    elements = soup.find_all("td", id=re.compile("^p_body_fld_"))

    由于显然可以有多个，因此我们将循环遍历它们并显示它们的文本

    for element in elements:
  print("Text: \n",element.text)

    剩下的就是检查找到的文本是否包含我们需要的单词

    for element in elements:
  if "УЦН" in element.text:
    print("Found!\n")
