【问题描述】：
我的 HTML 代码中有一个 Javascript。我想浏览以“Doc”结尾的链接。在这个 HTML 中只有一个链接，称为 SunnydataDoc。所以我想在这个页面上搜索这个字符串，如果存在任何以“Doc”结尾的链接，我想在这些页面中进一步向下导航。 你能帮我解决这个问题吗？我听说我可以将正则表达式和匹配方法与 Jsoup 结合使用。 这是我的代码。
<script>
var data = {"totalRecords": 2, "sort": "name", "startIndex": 0, "dir": "asc", "records": [{"raw_name": "samia/export/sunnydata", "last_changeset": "\n <div>\n <pre><a title=\"ownerID:\n\nAdded tag V2.11.d50.mkt.001 for changeset 56e10a4864ff\" class=\"tooltip\" href=\"/samia/export/sunnydata/changeset/f602409eba261d749d23dc75551b2959425dfa8d\">r17:f602409eba26</a></pre>\n </div>\n", "atom": "\n <a title=\"Subscribe to samia/export/sunnydata atom feed\" href=\"/samia/export/sunnydata/feed/atom?api_key=e214ebea2335318bee1460a1fd33725ab3e1002e\"><i class=\"icon-rss-sign\" style=\"color: #fa9b39\"></i></a>\n", "owner": "ownerID (Owner)", "rss": "\n <a title=\"Subscribe to samia/export/sunnydata rss feed\" href=\"/samia/export/sunnydata/feed/rss?api_key=e214ebea2335318bee1460a1fd33725ab3e1002e\"><i class=\"icon-rss-sign\" style=\"color: #fa9b39\"></i></a>\n", "name": "\n \n <div style=\"white-space: nowrap; }\">\n <a href=\"/samia/export/sunnydata\">\n\n <span title=\"Mercurial repository\"><i class=\"icon-hg\" style=\"color: #316293; font-size: 14px;\"></i></span>\n\n <span style=\"margin: 0px 8px 0px 8px\"></span>\n Sunnydata\n </a>\n </div>\n", "last_rev_raw": 17, "state": "\n <div>\n <div class=\"btn btn-mini btn-success disabled\">Created</div>\n </div>\n", "menu": "\n <ul class=\"menu_items hidden\">\n\n <li style=\"border-top:1px solid #003367;margin-left:18px;padding-left:-99px\"></li>\n <li>\n <a title=\"Summary\" href=\"/samia/export/sunnydata\">\n <span class=\"icon\">\n <i class=\"icon-file-text\"></i>\n </span>\n <span>Summary</span>\n </a>\n </li>\n <li>\n <a title=\"Changelog\" href=\"/samia/export/sunnydata/changelog\">\n <span class=\"icon\">\n <i class=\"icon-list-alt\"></i>\n </span>\n <span>Changelog</span>\n </a>\n </li>\n <li>\n <a title=\"Files\" href=\"/samia/export/sunnydata/files/tip/\">\n <span class=\"icon\">\n <i class=\"icon-file-alt\"></i>\n </span>\n <span>Files</span>\n </a>\n </li>\n <li>\n <a title=\"Fork\" href=\"/samia/export/sunnydata/fork\">\n <span class=\"icon\">\n <i class=\"icon-code-fork\"></i>\n </span>\n <span>Fork</span>\n </a>\n </li>\n </ul>\n", "desc": "GHU Sunnydataimport", "last_change": "\n <span class=\"tooltip\" date=\"2014-08-21 18:49:50\" title=\"Thu, 21 Aug 2014 18:49:50\">10 days and 16 hours ago</span>\n"}, {"raw_name": "samia/export/sunnydatadoc", "last_changeset": "\n <div>\n <pre><a title=\"ownerID;lt;owneremail;gt;:\n\nChangedokumentation\" class=\"tooltip\" href=\"/samia/export/sunnydataDoc/changeset/9ed1679c7a35b76e1402b540cee38000461fdfdd\">r0:9ed1679c7a35</a></pre>\n </div>\n", "atom": "\n <a title=\"Subscribe to samia/export/sunnydataDoc atom feed\" href=\"/samia/export/sunnydataDoc/feed/atom?api_key=e214ebea2335318bee1460a1fd33725ab3e1002e\"><i class=\"icon-rss-sign\" style=\"color: #fa9b39\"></i></a>\n", "owner": "ownerID (Owner)", "rss": "\n <a title=\"Subscribe to samia/export/sunnydataDoc rss feed\" href=\"/samia/export/sunnydataDoc/feed/rss?api_key=e214ebea2335318bee1460a1fd33725ab3e1002e\"><i class=\"icon-rss-sign\" style=\"color: #fa9b39\"></i></a>\n", "name": "\n \n <div style=\"white-space: nowrap; }\">\n <a href=\"/samia/export/sunnydataDoc\">\n\n <span title=\"Mercurial repository\"><i class=\"icon-hg\" style=\"color: #316293; font-size: 14px;\"></i></span>\n\n <span style=\"margin: 0px 8px 0px 8px\"></span>\n SunnydataDoc\n </a>\n </div>\n", "last_rev_raw": 0, "state": "\n <div>\n <div class=\"btn btn-mini btn-success disabled\">Created</div>\n </div>\n", "menu": "\n <ul class=\"menu_items hidden\">\n\n <li style=\"border-top:1px solid #003367;margin-left:18px;padding-left:-99px\"></li>\n <li>\n <a title=\"Summary\" href=\"/samia/export/sunnydataDoc\">\n <span class=\"icon\">\n <i class=\"icon-file-text\"></i>\n </span>\n <span>Summary</span>\n </a>\n </li>\n <li>\n <a title=\"Changelog\" href=\"/samia/export/sunnydataDoc/changelog\">\n <span class=\"icon\">\n <i class=\"icon-list-alt\"></i>\n </span>\n <span>Changelog</span>\n </a>\n </li>\n <li>\n <a title=\"Files\" href=\"/samia/export/sunnydataDoc/files/tip/\">\n <span class=\"icon\">\n <i class=\"icon-file-alt\"></i>\n </span>\n <span>Files</span>\n </a>\n </li>\n <li>\n <a title=\"Fork\" href=\"/samia/export/sunnydataDoc/fork\">\n <span class=\"icon\">\n <i class=\"icon-code-fork\"></i>\n </span>\n <span>Fork</span>\n </a>\n </li>\n </ul>\n", "desc": "GHU Sunnydataimport (Dokumentation)", "last_change": "\n <span class=\"tooltip\" date=\"2014-04-25 11:03:45\" title=\"Fri, 25 Apr 2014 11:03:45\">4 months and 6 days ago</span>\n"}]};
var myDataSource = new YAHOO.util.DataSource(data);
myDataSource.responseType = YAHOO.util.DataSource.TYPE_JSON;
所以在这个例子中我有这个链接：href=\"/samia/export/sunnydataDoc\"。我想获取此链接并使用我的代码进入那里。
这是我的 Java 代码。
public class JScripttest {
public static void main(String[] args) throws IOException {
Response res = Jsoup
.connect(
"url")
.data("username", "username", "password", "password")
.method(Method.POST).execute();
Map<String, String> loginCookies = res.cookies();
Document doc = Jsoup.connect("url")
.cookies(loginCookies).get();
Element script = doc.select("href").last();
Pattern p = Pattern.compile("href\s=\s"([^"]+Doc)""); // Regex for the value of the href
Matcher m = p.matcher(script.html()); // you have to use html here and NOT text! Text will drop the 'href' part
while( m.find() )
{
System.out.println(m.group());
System.out.println(m.group(1));
}
}
private static void print(String msg, Object... args) {
System.out.println(String.format(msg, args));
}
所以我在“Pattern....”行中出现错误
