将解析的链接保存到一个字符串或一个数组java

Question

String html = Jsoup.connect("www.example.com").get().html(); 
Scanner in = new Scanner(html); 

String links ; 
while(in.hasNext()){ 
    String line = in.nextLine(); 
    if(line.contains("sometext")){ 

String links += line.substring(line.indexOf("http").line.indexOf("</a>") + "\n"); 

    } 

我有上面的代码。它使用JSoup获取网页的HTML，之后，我想将它们保存为一个字符串或一个由新行分隔的数组。这是我的问题。

您应该继续使用jsoup来检索和解析HTML。另外，jsoup的文档address this。

String output = ""; 
// Get the webpage and parse it. 
Document doc = Jsoup.connect(url).get(); 
// Get the anchors with href attribute. 
// Or, you can use doc.select("a") to get all the anchors. 
Elements links = doc.select("a[href]"); 
// Iterate over all the links and process them. 
for (Element link : links) { 
    output += link.attr("abs:href"); 
}
