【问题描述】：

这是我上一个问题的后续问题。当我想使用this 问题中的参考将 html 字符串转换为没有 HTML 标签的谷歌应用脚​​本中的纯文本时遇到问题。但是，这次是段落格式。

这是我使用的脚本：

function pullDataFromWorkday() 
  var url = 'https://services1.myworkday.com/ccx/service/customreport2/[company name]/[owner's email]/[Report Name]?format=csv'; //this is the csv link from workday report
  var b64 = 'asdfghjklkjhgfdfghj=='; //this is supposed to be our workday password in b64
  var response = UrlFetchApp.fetch(url, 
      headers: 
        Authorization: 'Basic '+ b64
      
  );

//Parse   
  if (response.getResponseCode() >= 200 && response.getResponseCode() < 300) 
    var blob = response.getBlob();
    var string = blob.getDataAsString();
    var data = Utilities.parseCsv(string, ",");

    for(i=1;i<data.length;i++)
    

      data[i][0];
      data[i][1];
      data[i][2]=toStringFromHtml(data[i][2]);
      data[i][3]=toStringFromHtml(data[i][3]);
      data[i][4]=toStringFromHtml(data[i][4]);
      data[i][5]=toStringFromHtml(data[i][5]);
    

  //Paste  it in   
  var ss = SpreadsheetApp.getActive();
  var sheet = ss.getSheetByName('Sheet1');
  sheet.clear();
  sheet.getRange(1,1,data.length,data[0].length).setValues(data);
    

  else 
    return;
    
  



function toStringFromHtml(html)

  
html = '<div>' + html + '</div>';
html = html.replace(/<br>/g,"");
var document = XmlService.parse(html);
var strText = XmlService.getPrettyFormat().format(document);
strText = strText.replace(/<[^>]*>/g,"");
return strText.trim();

这是我想要的数据样本：

或者您可以使用这个sample 电子表格。

我有没有遗漏或做错的步骤？

感谢您之前回答问题

【参考方案1】：

我认为您可以使用这个库：[cheerio for Google Apps Script][1]

function htmltotext() 
  let html = `<p><span>Hi Katy</span></p><p></p><p><span>The illustration (examples) paragraph is useful when we want to explain or clarify something, such as an object, a person, a concept, or a situation. Sample Illustration Topics:</span></p><p></p><p></p><p><span>1. Examples of annoying habits people have on the Skytrain.</span></p><p><span>2. Positive habits that you admire in other people.   </span></p><p><span>3. Endangered animals in Asia. </span></p>`
  const $ = Cheerio.load(html)
  let paragraph = []
  let lines = $('p')
  for(let i = 0; i < lines.length;i++) 
    let line = lines.get((i))
    let line_text = $(line).text();
    if(line_text) 
      paragraph.push(line_text)
    
  
  Logger.log(paragraph.join('\n'))
  return paragraph.join('\n')

【讨论】：

您能否提供有关此软件包是什么、它的作用以及它如何帮助 OP 的更多信息？

Cheerio 是一个 GAS 帮助用户解析 html 的库。

@Tyler2P 请检查最后的评论。我已经更新了我的脚本

【参考方案2】：

你的情况，如何修改toStringFromHtml如下？

修改脚本：

function toStringFromHtml(html) 
  html = '<div>' + html + '</div>';
  html = html.replace(/<br>/g, "").replace(/<p><\/p><p><\/p>/g, "<p></p>").replace(/<span>|<\/span>/g, "");
  var document = XmlService.parse(html);
  var strText = XmlService.getPrettyFormat().setIndent("").format(document);
  strText = strText.replace(/<[^>]*>/g, "");
  return strText.trim();

在此修改后的脚本中，您的以下示例 HTML 转换如下。

来自

  <p><span>Hi Katy</span></p>
  <p></p>
  <p><span>The illustration (examples) paragraph is useful when we want to explain or clarify something, such as an object, a person, a concept, or a situation. Sample Illustration Topics:</span></p>
  <p></p>
  <p></p>
  <p><span>1. Examples of annoying habits people have on the Skytrain.</span></p>
  <p><span>2. Positive habits that you admire in other people. </span></p>
  <p><span>3. Endangered animals in Asia. </span></p>

到

  <div>
    <p>Hi Katy</p>
    <p></p>
    <p>The illustration (examples) paragraph is useful when we want to explain or clarify something,
      such as an object,
      a person,
      a concept,
      or a situation. Sample Illustration Topics:</p>
    <p></p>
    <p>1. Examples of annoying habits people have on the Skytrain.</p>
    <p>2. Positive habits that you admire in other people. </p>
    <p>3. Endangered animals in Asia. </p>
  </div>

通过这种转换，得到以下结果。

  Hi Katy

  The illustration (examples) paragraph is useful when we want to explain or clarify something, such as an object, a person, a concept, or a situation. Sample Illustration Topics:

  1. Examples of annoying habits people have on the Skytrain.
  2. Positive habits that you admire in other people.
  3. Endangered animals in Asia.

注意：

使用问题中显示的示例 HTML 时，修改后的脚本可以实现您的目标。但是，我不确定您的其他 HTML 数据。所以我不确定这个修改后的脚本是否可以用于您的实际 HTML 数据。请注意这一点。

嗨@tanaike 非常感谢你！现在它工作正常。我通过删除 "replace(/|/g, "")" 稍微修改了脚本，因为显然不是所有写在 "" 中的原始数据跨度>

@Nadila 感谢您的回复。很高兴您的问题得到解决。
