Release Notes

jhy/jsoup (org.jsoup:jsoup)

v1.23.1

Improvements

• Reduced retained memory when parsing with source position tracking enabled (Parser#setTrackPosition(true)). Source ranges are now stored in compact parser-owned span records instead of node and attribute user data, and Position objects are created lazily when source ranges are read. This cuts tracked DOM retained size by about 50-60% on representative benchmark documents, while keeping Node#sourceRange(), Element#endSourceRange(), and Attribute#sourceRange() behavior intact. #​2498
• Added Element#classList(), an immutable snapshot of an element's class names in attribute order. Use hasClass() when you just need to test for one class, classList() when you want to read or iterate classes without needing a mutable result, and classNames() when you want the existing mutable, deduplicated set that can be written back with classNames(Set). The class APIs now share an HTML-whitespace scanner, which also makes classNames() faster and lighter on allocation, especially when walking many elements without class names. #​2500
• Aligned HTML parser scope classification with the current HTML spec for select, foreignObject, and template. #​2501
• Simplified the HTML tree builder's scope, implied-end-tag, and special-element checks by caching parser-only options on Tag. That improves HTML parser throughput by about 10% on small inputs and up to about 30% on larger inputs in the benchmark fixtures. #​2502
• Improved HTML parser throughput stability by making hot tokeniser scan paths compile more predictably. #​2507
• <noscript> fallback markup is now parsed into an inspectable DOM subtree in both the document head and body. The fallback acts as a contained parsing island, so malformed markup cannot disrupt the surrounding document structure, while normal HTML tokenization still applies within it. This also improves round-trip serialization. #​2537
• Improved redirect credential handling as a defense-in-depth measure: explicit authorization headers and request cookies are no longer forwarded across origins, reducing exposure through open redirects and aligning with HTTP guidance. Cookies managed by a CookieStore continue to follow their configured scope. #​2540
• Elements can now append their outer HTML, including their own tags, directly to an Appendable with Node#outerHtml(Appendable), without first creating a String. This complements Element#html(Appendable), which appends inner HTML only. #​2532
• Aligned CDATA tokenization with the HTML spec: CDATA syntax in HTML content is parsed as a bogus comment, while it remains supported in SVG, MathML, and XML. Also improved namespace-aware fragment parsing so SVG and MathML contexts, HTML integration points, and context-sensitive tokenizer states are handled correctly. #​2542
• When using the optional re2j regular expression engine, stack overflows caused by complex selector patterns are now normalized to a ValidationException with a Pattern complexity error message. #​2548

Bug Fixes

• Fixed HTML parsing of mixed-case RCDATA end tags after tag-shaped text. For example, <title><p>Foo</TiTLE> and <textarea><img src=x></TeXtArEa> now keep the tag-shaped content as text instead of promoting it to markup. #​2503
• Fixed W3CDom XML conversion so plain XML elements don't serialize with the reserved XML namespace as the default namespace. Explicit XML namespaces and xml:* attributes are still preserved. #​2504
• Preserve control characters in parsed tag names #​2538
• Updated HTTP redirects to follow the specification: 307 and 308 preserve the request method and content, 301 and 302 only change POST to GET, and Location is followed only for 301, 302, 303, 307, and 308 responses. Streamed request bodies are not buffered; if an automatic redirect requires replaying one, execution fails, so the caller can resend with a fresh stream. #​2540
• Corrected the Cleaner's same-site link detection to compare hostnames rather than URL prefixes when applying rel=nofollow. #​2543

Build Changes

• Cleaned up the Maven build for the multi-release JAR so Java 8 and Java 11+ sources compile as separate source sets. This avoids spurious Java 8 compiler warnings from newer-language overlay sources, keeps long-running parser checks behind an explicit profile, and preserves the same published artifacts and runtime behavior.
• Improved parallelism and tuned timing in our integration tests, so that a full mvn clean verify drops from ~ 1m18s to ~ 21 seconds.

v1.22.2

Improvements

• Expanded and clarified NodeTraversor support for in-place DOM rewrites during NodeVisitor.head(). Current-node edits such as remove, replace, and unwrap now recover more predictably, while traversal stays within the original root subtree. This makes single-pass tree cleanup and normalization visitors easier to write, for example when unwrapping presentational elements or replacing text nodes as you walk the DOM. #​2472
• Documentation: clarified that a configured Cleaner may be reused across concurrent threads, and that shared Safelist instances should not be mutated while in use. #​2473
• Updated the default HTML TagSet for current HTML elements: added dialog, search, picture, and slot; made ins, del, button, audio, video, and canvas inline by default (Tag#isInline(), aligned to phrasing content in the spec); and added readable Element.text() boundaries for controls and embedded objects via the new Tag.TextBoundary option. This improves pretty-printing and keeps normalized text from running adjacent words together. #​2493

Bug Fixes

• Android (R8/ProGuard): added a rule to ignore the optional re2j dependency when not present. #​2459
• Fixed a NodeTraversor regression in 1.21.2 where removing or replacing the current node during head() could revisit the replacement node and loop indefinitely. The traversal docs now also clarify which inserted nodes are visited in the current pass. #​2472
• Parsing during charset sniffing no longer fails if an advisory available() call throws IOException, as seen on JDK 8 HttpURLConnection. #​2474
• Cleaner no longer makes relative URL attributes in the input document absolute when cleaning or validating a Document. URL normalization now applies only to the cleaned output, and Safelist.isSafeAttribute() is side effect free. #​2475
• Cleaner no longer duplicates enforced attributes when the input Document preserves attribute case. A case-variant source attribute is now replaced by the enforced attribute in the cleaned output. #​2476
• If a per-request SOCKS proxy is configured, jsoup now avoids using the JDK HttpClient, because the JDK would silently ignore that proxy and attempt to connect directly. Those requests now fall back to the legacy HttpURLConnection transport instead, which does support SOCKS. #​2468
• Connection.Response.streamParser() and DataUtil.streamParser(Path, ...) could fail on small inputs without a declared charset, if the initial 5 KB charset sniff fully consumed the input and closed it before the stream parse began. #​2483
• In XML mode, doctypes with an internal subset, such as <!DOCTYPE root [<!ENTITY name "value">]>, now round-trip correctly. The subset is preserved as raw text only; entities are not expanded and external DTDs are not loaded. #​2486

Build Changes

• Migrated the integration test server from Jetty to Netty, which actively maintains support for our minimum JDK target (8). #​2491

v1.22.1

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 org.jsoup.helper.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 org.jsoup.parser.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

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
