数据=

<div class="dojoxGridView" id="dojox_grid__View_1" role="presentation" style="width: 1900px; height: 721px; left: 1px; top: 0px;" widgetid="dojox_grid__View_1">

         <div role="presentation" style="position: absolute; left: 0px; top: 0px;">
          <div aria-selected="false" class="dojoxGridRow" role="row" style="">
           <table border="0" cellpadding="0" cellspacing="0" class="dojoxGridRowTable" role="presentation" style="width: 1900px;">

              <td class="dojoxGridCell" idx="0" role="gridcell" style="display:none;width:100px;" tabindex="-1">
               78126
              </td>
              <td class="dojoxGridCell" idx="1" role="gridcell" style="width:10%;" tabindex="-1">
               Approved Plan
              </td>
              <td class="dojoxGridCell" idx="2" role="gridcell" style="width:10%;" tabindex="-1">
               G-10
              </td>
              <td class="dojoxGridCell" idx="3" role="gridcell" style="width:40%;" tabindex="-1">
               ROOF PLAN
              </td>
             </tr>
            </tbody>
           </table>
          </div>

输入=

    source = driver.page_source
soup = BeautifulSoup(source, "lxml")
print(soup. prettify())
for article in soup.find_all('div', class_='dojoxGridContent'):
drawing_no = article.find_all('td', class_='dojoxGridCell', idx='3')
# ->need one more line to extract text
print(""drawing_no")

Output =

<td class="dojoxGridCell" idx="3" role="gridcell" style="width:40%;" tabindex="-1">ROOF PLAN</td> ...

我只想提取“屋顶计划”，我应该如何编辑我的代码？我尝试了drawing_no.text和drawing_no.value，但它说“无属性”。感谢您的帮助！

Answer 1

请尝试以下代码。但是通常，如果您传入idx = 3，它将仅返回一个元素。如果要从多个元素中提取文本，则可能需要使用更通用的标识符。

import lxml
from lxml import html

html_string = """
<div class="dojoxGridView" id="dojox_grid__View_1" role="presentation" style="width: 1900px; height: 721px; left: 1px; top: 0px;" widgetid="dojox_grid__View_1">
  <input class="dojoxGridHiddenFocus" dojoattachpoint="hiddenFocusNode" role="presentation" type="checkbox"/>
  <input class="dojoxGridHiddenFocus" role="presentation" type="checkbox"/>
  <div class="dojoxGridScrollbox" dojoattachpoint="scrollboxNode" role="presentation" style="height: 721px;">
    <div class="dojoxGridContent" dojoattachpoint="contentNode" hidefocus="hidefocus" role="presentation" style="height: 504px; width: 1900px;">
      <div role="presentation" style="position: absolute; left: 0px; top: 0px;">
        <div aria-selected="false" class="dojoxGridRow" role="row" style="">
          <table border="0" cellpadding="0" cellspacing="0" class="dojoxGridRowTable" role="presentation" style="width: 1900px;">
            <tbody>
              <tr>
                <td class="dojoxGridCell" idx="0" role="gridcell" style="display:none;width:100px;" tabindex="-1">
                78126
                </td>
                <td class="dojoxGridCell" idx="1" role="gridcell" style="width:10%;" tabindex="-1">
                Approved Plan
                </td>
                <td class="dojoxGridCell" idx="2" role="gridcell" style="width:10%;" tabindex="-1">

"""

tree = html.fromstring(html_string)
ROOFPLAN = tree.xpath('//tbody/tr//td[@idx="3"]/text()')
print(''.join(ROOFPLAN).strip())

  drawing_no = article.find('td', class_='dojoxGridCell', idx='3')
  if drawing_no:
    print(drawing_no.get_text())

Answer 3

您可以使用public void CreateTableIfMissing() { var info = new StorageInfo(); // initialized with tablename and connectionstring var storageAccount = CloudStorageAccount.Parse(info.ConnectionString); var tableClient = storageAccount.CreateCloudTableClient(); var table = tableClient.GetTableReference(info.TableName); try { table.CreateIfNotExists(); var s = DateTime.Now.ToString("o"); var entry = new TableEntity("partkey" + s, "rowkey" + s); var op = TableOperation.Insert(entry); table.Execute(op); } catch (Exception e) { Console.WriteLine(e); throw; } }属性并按其值进行选择
