jsoup 1.11.1 发布了，该版本降低了 30% 的 DOM 内存使用，增加了流式网络 HTML 解析，更快的 HTML 生成以及大量的改进和 bug 修复，下载地址：https://jsoup.org/download 详细的改进内容如下： Improvements When loading content from a URL or a file, the content is now parsed as it streams in from the network or disk, rather than being fully buffered before parsing. This substantially reduces memory consumption & large garbage objects when loading large files. Note that this change means that a response, once parsed, may not be parsed again from the same response object unless you call Connection.Response.bufferUp() first, which will buffer the full response into memory. Updated language level to Java 7 from Java 5. To maintain Android support (of minversion 8), try-with-resources are not used. Added Connection.Response.bodyStream(), a method to get the response body as an input stream. This is useful for saving a large response straight to a file, without buffering fully into memory first. Performance improvements in text and HTML generation (through less GC). Reduced memory consumption of text, scripts, and comments in the DOM by 40%, by refactoring the node hierarchy to not track childnodes or attributes by default for lead nodes. For the average document, that's about a 30% memory reduction. Reduced memory consumption of Elements by refactoring their Attributesto be a simple pair of arrays, vs a LinkedHashSet. Added support for Element.selectFirst(), to efficiently find the first matching element. Added Element.appendTo(parent) to simplify slinging elements about. Added support for multiple headers with the same name in Jsoup.Connect Added Element.shallowClone() and Node.shallowClone(), to allow cloning nodes without getting all their children. Updated Element.text() and the :contains(text) selector to consider character as spaces. Updated Jsoup.connect().timeout() to implement a total connect + combined read timeout. Previously it specified connect and buffer read times only, so to implement a combined total timeout, you had to have another thread send an interupt. Improved performance of Node.addChildren() (was quadratic) Added missing support for template tags in tables In Jsoup.Connect file uploads, added the ability to set the uploaded files' mimetype. Improved Node traversal, including less object creation, and partial and filtering traversor support. Bug Fixes Bugfix: if a document was was redecoded after character set detection, the HTML parser was not reset correctly, which could lead to an incorrect DOM. Bugfix: attributes with the same name but different case would be incorrectly treated as different attributes. Bugfix: self-closing tags for known empty elements were incorrectly treated as errors. Bugfix: fixed an issue where a self-closing title, noframes, or style tag would cause the rest of the page to be incorrectly parsed as data or text. Bugfix: fixed an issue with unknown mixed-case tags Bugfix: fixed an issue where the entity resources were left open after startup, causing a warning. Bugfix: fixed an issue where Element.getElementsByIndexLessThan(index) would incorrectly provide the root element Improved parse time for pages with exceptionally deeply nested tags. Improvement / workaround: modified the Entities implementation to load its data from a .class vs from a jar resource. Faster, and safer on Android. jsoup 1.11.1 发布，最强的 Java HTML 解析器下载地址
