jsoup HTML解析器
jsoup 是一款 Java 的HTML 解析器，可直接解析某个URL地址、HTML文本内容。它提供了一套非常省力的API，可通过DOM，CSS以及类似于JQuery的操作方法来取出和操作数据。
jsoup 1.9.1 发布。
更新日志：
改进：
Added support for HTTP and SOCKS request proxies, specifiable per connection. See Connection.proxy(String, int).
Added support for sending plain HTTP request bodies in POST and PUT requests, with Connection.requestBody(String).
Added support in Jsoup.Connect() for HEAD, OPTIONS, and TRACE.
Added support for HTTP 307 Temporary Redirect (replays posts, if applicable).
Performance improvements when parsing HTML, particularly on Android Dalvik.
Added support for writing HTML into Appendable objects (like OutputStreamWriter), to enable stream serialization. See Node.html(T)
Added support for XML namespaces when converting jsoup documents to W3C documents.
Added support for UTF-16 and UTF-32 character set detection from byte-order-marks (BOM).
Added support for tags with non-ascii (unicode) letters.
Added Connection.data(String) to retrieve a data KeyVal by its key. Useful to update form data before submission.
Bug 修复
Fixed an issue in the Parent selector where it would not match against the root element it was applied to.
Fix an issue where Elements.select(String) would not return every matching element if they had the same content.
Added not-null validators to Element.appendText() and Element.prependText()
Fixed an issue when moving moving nodes using Element.insert(int, Collection) where the sibling index would be set incorrectly, leading to the original loads being lost.
Reverted Node.equals() and Node.hashCode() back to identity (object) comparisons, as deep content inspection had negative performance impacts and hashkey stability problems. Functionality replaced with Node.hasSameValue().
In Connection, if the same header key is seen multiple times, combine their values with a comma per the HTTP RFC, instead of keeping just one value. Also fixes an issue where header values could be out of order.
