Java 如何获取src url和a href html

我有这段html代码。我想替换三个单独属性中提到的内容的链接占位符。这就是我迄今为止所尝试的：

    String texto2 = "url(\"primeiro url\")\n" +
    "url('2 url')\n" +
    "href=\"1 href\"\n" +
    "src=\"1 src\"\n" +
    "src='2 src'\n" +
    "url('3 url')\n" +
    "\n" +
    ".camera_target_content .camera_link {\n" +
    "   background: url(../images/blank.gif);\n" +
    "   display: block;\n" +
    "   height: 100%;\n" +
    "   text-decoration: none;\n" +
    "}";

    String exp = "(?:href|src)=[\"'](.+)[\"']+|(?:url)\\([\"']*(.*)[\"']*\\)";
    // expressão para pegar os links do src e do href
    Pattern pattern = Pattern.compile(exp);

    // preparando expressao
    Matcher matcher = pattern.matcher(texto2); 


    // pegando urls e guardando na lista
    while(matcher.find()) {


    System.out.println(texto2.substring(matcher.start(), matcher.end()));   
    }

        String texto2 = "url(\"primeiro url\")\n" +
    "url('2 url')\n" +
    "href=\"1 href\"\n" +
    "src=\"1 src\"\n" +
    "src='2 src'\n" +
    "url('3 url')\n" +
    "\n" +
    ".camera_target_content .camera_link {\n" +
    "   background: url(../images/blank.gif);\n" +
    "   display: block;\n" +
    "   height: 100%;\n" +
    "   text-decoration: none;\n" +
    "}";

    String exp = "(?:href|src)=[\"'](.+)[\"']+|(?:url)\\([\"']*(.*)[\"']*\\)";
    // expressão para pegar os links do src e do href
    Pattern pattern = Pattern.compile(exp);

    // preparando expressao
    Matcher matcher = pattern.matcher(texto2); 


    // pegando urls e guardando na lista
    while(matcher.find()) {


    String s = matcher.group(2);
    System.out.println(s);  


    }

到目前为止，一切都很好-它与find一起工作，我需要获得干净的链接，如下所示：

  img/image.gif

而不是：

 href = "img/image.gif"

src=“img/image.gif” url（img/image.gif）

我想用一个变量替换一个占位符；这就是我迄今为止所尝试的：

    String texto2 = "url(\"primeiro url\")\n" +
    "url('2 url')\n" +
    "href=\"1 href\"\n" +
    "src=\"1 src\"\n" +
    "src='2 src'\n" +
    "url('3 url')\n" +
    "\n" +
    ".camera_target_content .camera_link {\n" +
    "   background: url(../images/blank.gif);\n" +
    "   display: block;\n" +
    "   height: 100%;\n" +
    "   text-decoration: none;\n" +
    "}";

    String exp = "(?:href|src)=[\"'](.+)[\"']+|(?:url)\\([\"']*(.*)[\"']*\\)";
    // expressão para pegar os links do src e do href
    Pattern pattern = Pattern.compile(exp);

    // preparando expressao
    Matcher matcher = pattern.matcher(texto2); 


    // pegando urls e guardando na lista
    while(matcher.find()) {


    System.out.println(texto2.substring(matcher.start(), matcher.end()));   
    }

        String texto2 = "url(\"primeiro url\")\n" +
    "url('2 url')\n" +
    "href=\"1 href\"\n" +
    "src=\"1 src\"\n" +
    "src='2 src'\n" +
    "url('3 url')\n" +
    "\n" +
    ".camera_target_content .camera_link {\n" +
    "   background: url(../images/blank.gif);\n" +
    "   display: block;\n" +
    "   height: 100%;\n" +
    "   text-decoration: none;\n" +
    "}";

    String exp = "(?:href|src)=[\"'](.+)[\"']+|(?:url)\\([\"']*(.*)[\"']*\\)";
    // expressão para pegar os links do src e do href
    Pattern pattern = Pattern.compile(exp);

    // preparando expressao
    Matcher matcher = pattern.matcher(texto2); 


    // pegando urls e guardando na lista
    while(matcher.find()) {


    String s = matcher.group(2);
    System.out.println(s);  


    }

事实证明，这个版本不起作用。它完美地抓住了url；有人能帮我找出问题吗？

使用。将HTML字符串解析为DOM，然后可以使用CSS选择器提取值，就像在JavaScript中使用jQuery一样。请注意，这仅在您实际使用HTML时有效；示例顶部的字符串不是HTML。

“我是HTML文本，需要向他提供链接…”使用HTML解析器。否则，我在哪里找到这个html解析器？搜索引擎“java html parse”…这太完美了，谢谢
