正则表达式匹配标签之间的文本

Question

我有这个字符串:

My name is <b>Bob</b>, I'm <b>20</b> years old, I like <b>programming</b>.

我想将b标签之间的文本转换为数组,即:

['Bob', '20', 'programming']

我尝试了这个,/<b>(.*?)<\/b>/.exec(str)但它只会得到第一个文本.

Answer 1

/<b>(.*?)<\/b>/g

添加g(全局)标志后:

/<b>(.*?)<\/b>/g.exec(str)
             //^-----here it is 

但是,如果你想获得所有匹配的元素,那么你需要这样的东西:

var str = "<b>Bob</b>, I'm <b>20</b> years old, I like <b>programming</b>.";

var result = str.match(/<b>(.*?)<\/b>/g).map(function(val){
   return val.replace(/<\/?b>/g,'');
});
//result -> ["Bob", "20", "programming"] 

Answer 2

var root = document.createElement("div");

root.innerHTML = "My name is <b>Bob</b>, I'm <b>20</b> years old, I like <b>programming</b>.";

var texts = [].map.call( root.querySelectorAll("b"), function(v){
    return v.textContent || v.innerText || "";
});

//["Bob", "20", "programming"]

Answer 3

改为使用匹配和g标志.

str.match(/<b>(.*?)<\/b>/g);
