将HTML字符串解析为数组

Question

I have an html string that contains multiple <p> tags. WIthin each <p> tag there is a word and its definition.

let data = "<p><strong>Word 1:</strong> Definition of word 1</p><p><strong>Word 2:</strong> Definition of word 2</p>"

My goal is to convert this html string into an array of objects that looks like below:

[
 {"word": "Word 1", "definition": "Definition of word 1"},
 {"word": "Word 2", "definition": "Definition of word 2"}
]

I am doing it as follows:

var parser = new DOMParser();
  var parsedHtml    = parser.parseFromString(data, "text/html");
  let pTags = parsedHtml.getElementsByTagName("p");
  let vocab = []
  pTags.forEach(function(item){
    // This is where I need help to split and convert item into object
    vocab.push(item.innerHTML)
  });

As you can see the comment in the above code, that is where I'm stuck. Any help is appreciated.

Answer 1

Use textContent to get the text out of an element. The word is in the strong child element, the definition is the rest of the text.

var parser = new DomParser();
  var parsedHtml    = parser.parseFromString(data, "text/html");
  let pTags = parsedHtml.getElementsByTagName("p");
  let vocab = []
  pTags.forEach(function(item){
    let word = item.getElementsByTagName("strong")[0].textContent.trim();
    let allText = item.textContent;
    let definition = allText.replace(word, "").trim();
    vocab.push({word: word, definition: definition})
  });

A bit adhoc but works.

 const data = "<p><strong>Word 1:</strong> Definition of word 1</p><p><strong>Word 2:</strong> Definition of word 2</p>"; const parsedData = [ { "word1": data.split('<strong>')[1].split('</strong>')[0].trim(), "definition": data.split('</strong>')[1].split('</p>')[0].trim() }, { "word2": data.split('</p>')[1].split('<strong>')[1].split('</strong>')[0].trim(), "definition": data.split('</p>')[1].split('</strong>')[1].split('</p>')[0].trim() } ] console.log(parsedData); 

Answer 3

You should fix:

• DOMParser , not DomParser
• pTags cannot use .forEach() , please use for loop

My solution for your problem:

 let data = "<p><strong>Word 1:</strong> Definition of word 1</p><p><strong>Word 2:</strong> Definition of word 2</p>" var parser = new DOMParser(); var parsedHtml = parser.parseFromString(data, "text/html"); let pTags = parsedHtml.getElementsByTagName("p"); let vocab = []; for (let p of pTags) { const word = p.getElementsByTagName('strong')[0].innerHTML.replace(':', '').trim(); const definition = p.innerHTML.replace(/<strong>.*<\\/strong>/, '').trim(); vocab.push( { word, definition } ) } console.log(vocab);
