用于获取html起始标记的正则表达式

Question

I want get only the starting html tags. Lets say I have html like this

<div class="some">Here is a sample text<br /><p>A paragraph here</p></div>
<ul><li>List Item</li></ul>

From the above html I want to extract this information

<div
<br
<p
<ul
<li

see I dont need ending '>' of tags

Answer 1

Try regex /<[a-zA-Z]+[1-6]?/g . I added the [1-6] for the header HTML tags - I think they're the only ones with numbers. If you wanted to be sure you could do /<[a-zA-Z0-9]+/g , since in HTML a < is always a tag (unless it's a comment <-- ), because in-line < get converted to < .

Answer 2

以下内容将返回一个匹配数组，其中包含您想要的html正文。

'<div class="some">Here is a sample text<br /><p>A paragraph here</p></div><ul><li>List Item</li></ul>'.match(/<\w+/g)

Answer 3

How about this:

String input = "<div class=\"some\">Here is a sample text<br /><p>A paragraph here</p></div><ul><li>List Item</li></ul><6>";
Scanner scanner = new Scanner(input);
String result = "";
while( (result = scanner.findInLine("<\\w+")) !=null ){
    System.out.println(result);
}
