如何从HTML字符串获取头部和身体标签作为字符串? [英] How to get head and body tags as a string from html string?

问题描述

嘿，我有一个html字符串，我无法从中获取标签.

Hey i have an html string i'm having trouble getting the tags from.

我尝试了很多东西，这里是一些:

I have tried alot of stuff, here are some :

var head = $("head",$(htmlString)).html();
var body = $("body",$(htmlString)).html();
var head = $("head",htmlString).html();
var body = $("body",htmlString).html();
var head = $("head",$(htmlString).html()).html();
var body = $("body",$(htmlString).html()).html();
var head = htmlString.match(/<head[^>]*>([^<]+)<\/head>/);
var body = htmlString.match(/<body[^>]*>([^<]+)<\/body>/);
var head = jQuery('<div/>').append(htmlString).find('head').html();
var body = jQuery('<div/>').append(htmlString).find('body').html();

除此之外，还有许多其他尝试.当我尝试将其登录到控制台时，所有这些都返回"undefined"或"或jquery对象.

Any many other tries besides that. All of this return "undefined" or "" or jquery object when i try loging it to console.

谁能告诉我如何将身体和头部标签作为字符串?

Could anyone tell me how can i get the body and head tags as a string?

首选jQuery/JS而不是正则表达式

推荐答案

尝试以下代码:

var head = htmlString.match(/<head[^>]*>[\s\S]*<\/head>/gi);
var body = htmlString.match(/<body[^>]*>[\s\S]*<\/body>/gi);
