jsoup Java HTML Parser release 1.22.1

jsoup 1.22.1 is out now, adding support for the re2j regular expression engine for regex-based CSS selectors, a configurable maximum parser depth, and numerous bug fixes and improvements.

jsoup is a Java library for working with real-world HTML and XML. It provides a very convenient API for extracting and manipulating data, using the best of HTML5 DOM methods and CSS selectors.

Improvements

• Added support for using the re2j regular expression engine for regex-based CSS selectors (e.g. [attr~=regex], :matches(regex)), which ensures linear-time performance for regex evaluation. This allows safer handling of arbitrary user-supplied query regexes. To enable, add the com.google.re2j dependency to your classpath, e.g.:

  <dependency>
    <groupId>com.google.re2j</groupId>
    <artifactId>re2j</artifactId>
    <version>1.8</version>
  </dependency>

(If you already have that dependency in your classpath, but you want to keep using the Java regex engine, you can disable re2j via System.setProperty("jsoup.useRe2j", "false").) You can confirm that the re2j engine has been enabled correctly by calling Regex.usingRe2j(). #2407

• Added an instance method Parser#unescape(String, boolean) that unescapes HTML entities using the parser's configuration (e.g. to support error tracking), complementing the existing static utility Parser.unescapeEntities(String, boolean). #2396
• Added a configurable maximum parser depth (to limit the number of open elements on stack) to both HTML and XML parsers. The HTML parser now defaults to a depth of 512 to match browser behavior, and protect against unbounded stack growth, while the XML parser keeps unlimited depth by default, but can opt into a limit via Parser.setMaxDepth(). #2421
• Build: added CI coverage for JDK 25 #2403
• Build: added a CI fuzzer for contextual fragment parsing (in addition to existing full body HTML and XML fuzzers). [oss-fuzz #14041](google/oss-fuzz#14041)

Changes

• Set a removal schedule of jsoup 1.24.1 for previously deprecated APIs.

Bug Fixes

• Previously cached child Elements of an Element were not correctly invalidated in Node#replaceWith(Node), which could lead to incorrect results when subsequently calling Element#children(). #2391
• Attribute selector values are now compared literally without trimming. Previously, jsoup trimmed whitespace from selector values and from element attribute values, which could cause mismatches with browser behavior (e.g. [attr=" foo "]). Now matches align with the CSS specification and browser engines. #2380
• When using the JDK HttpClient, any system default proxy (ProxySelector.getDefault()) was ignored. Now, the system proxy is used if a per-request proxy is not set. #2388, #2390
• A ValidationException could be thrown in the adoption agency algorithm with particularly broken input. Now logged as a parse error. #2393
• Null characters in the HTML body were not consistently removed; and in foreign content were not correctly replaced. #2395
• An IndexOutOfBoundsException could be thrown when parsing a body fragment with crafted input. Now logged as a parse error. #2397, #2406
• When using StructuralEvaluators (e.g., a parent child selector) across many retained threads, their memoized results could also be retained, increasing memory use. These results are now cleared immediately after use, reducing overall memory consumption. #2411
• Cloning a Parser now preserves any custom TagSet applied to the parser. #2422, #2423
• Custom tags marked as Tag.Void now parse and serialize like the built-in void elements: they no longer consume following content, and the XML serializer emits the expected self-closing form. #2425
• The <br> element is once again classified as an inline tag (Tag.isBlock() == false), matching common developer expectations and its role as phrasing content in HTML, while pretty-printing and text extraction continue to treat it as a line break in the rendered output. #2387, #2439
• Fixed an intermittent truncation issue when fetching and parsing remote documents via Jsoup.connect(url).get(). On responses without a charset header, the initial charset sniff could sometimes (depending on buffering / available() behavior) be mistaken for end-of-stream and a partial parse reused, dropping trailing content. #2448
• TagSet copies no longer mutate their template during lazy lookups, preventing cross-thread ConcurrentModificationException when parsing with shared sessions. #2453
• Fixed parsing of <svg> foreignObject content nested within a <p>, which could incorrectly move the HTML subtree outside the SVG. #2452

Internal Changes

• Deprecated internal helper org.jsoup.internal.Functions (for removal in v1.23.1). This was previously used to support older Android API levels without full java.util.function coverage; jsoup now requires core library desugaring so this indirection is no longer necessary. #2412
