I got a html file like this:

HTML

<!document>
<!--alo 123-->
<html>
<head>
<title>TEST</title>
</head>
<body>
<!--alo 123-->
<span>hello and cut the site</span>

<div>
<header>
<div>
<!--alo 123-->
<span>header here!</span>
</div>
</header>
</div>

<p> This is 123</p>
<content >
<!--alo 123-->
<ul>
<li>a</li>
<li>b</li>
<li>c</li>
</ul>
</content>
<p> This is 345</p>

<div>
<!--alo 123-->
<footer><!--alo 123-->
<div>footer here</div></footer>
</div>
<br/>
<h2>hahaha</h2>
</body>
</html>

With Jsoup, i got

HTML

<div>

tag, which before my <content> tag; and

HTML

<div>

tags, which are before/after

HTML

<content>

tag as arguments in my function:

C#

private  void extractPage(Element previousTag,Element nextTag)throws IOException    
{ 
        Document doc = getDocHTML("product.html");      
        String str=previousTag.tagName()+"~*";
        Elements rs= doc.select(str);   
        String str2=nextTag.tagName()+"~*";       
        Elements rs2=rs.select(str2).remove();        
        this.messager.show(rs.outerHtml());
    }

I want to extract everything between my 2 previousTag and nextTag.
But with my function, i can't do it now.
I want to get result as this :

HTML

<p> This is 123</p>
<content >
<!--alo 123-->
<ul>
<li>a</li>
<li>b</li>
<li>c</li>
</ul>
</content>
<p> This is 345</p>

Please help me.
