jsoup 1.23.2

jsoup 1.23.2 is out now. This release focuses largely on bug fixes, specification correctness, and performance improvements.

It brings closer alignment with the HTML, XML, URL, and form submission specifications; improves XML and W3C DOM conversion; and makes HTTP workloads more efficient through streamed request bodies and broader JDK HttpClient reuse.

This version also includes new node insertion methods for Elements, and DOM mutations now reject operations that would create a cycle.

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

• Improved consecutive StreamParser.selectFirst() calls during progressive parsing, so later matches are returned with their parsed contents when earlier selections had left them as parser lookahead. E.g., given <title>One</title><p id=hit>Full</p><p>Next</p>, selecting title and then #hit now advances the partial lookahead and returns <p id="hit">Full</p>, rather than returning an empty <p id="hit"></p> before its content is parsed. The updated readiness tracking follows StreamParser's normal emission order across implicit HTML structure and parser recovery. #2551
• Improved XML parser performance and memory use for documents with many nested namespace declarations by recording namespace changes within each element scope. #2556
• Improved W3CDom conversion performance for documents with many nested namespace declarations. The W3C converter now uses the same optimized namespace tracking as the XML parser. #2559
• Improved W3CDom XML conversion to retain processing instructions, comments outside the root element, and CDATA sections, which were previously dropped or converted to text. #2572
• DOM mutation methods, including child insertion and replacement, now reject operations that would create a cycle, such as making a node its own child or moving an ancestor beneath a descendant. #2552
• Added Elements#before(Node), after(Node), prepend(Node), and append(Node) to match the existing HTML string methods. #953
• Large file-backed uploads through Connection.requestBodyStream(InputStream) now stream directly with the JDK HttpClient on Java 11+, rather than being loaded fully into memory first. #2575
• Extended Java 11+ HTTP client reuse from requests sharing a Jsoup.newSession() to ordinary Jsoup.connect() calls, reducing transport thread and connection setup churn under sustained request loads. Sessions with custom authentication or SSL contexts continue to use their own client. #2584

Changes

• Aligned the XML parser stack depth and lookups to the configured maximum, which now defaults to 512 for both HTML and XML. Use Parser#setMaxDepth(int) to configure. #2570

Bug Fixes

• Fixed W3CDom namespace conversion in several cases: #2559
  • Namespace declarations and prefixed attributes now carry the correct namespace URI, so namespace-aware DOM lookups work as expected.
  • Attributes added after parsing, or included through subtree conversion, now use inherited prefix declarations.
  • Namespace declarations now apply regardless of attribute order, and an empty declaration shadows an inherited binding only within its scope.
  • With namespace awareness disabled, inherited and undeclared prefixes now receive the declarations needed for XML serialization.
  • Valid HTML names that are not XML QNames, such as a:b:c, are normalized. Attributes that still cannot be represented are skipped, and unrepresentable elements no longer change the surrounding tree.
• Fixed W3CDom conversion of programmatically created or renamed elements whose names can be represented in a jsoup HTML DOM but are not valid XML names, such as 1abc. These names are now normalized (e.g. _1abc) instead of causing a NullPointerException. #2560
• Fixed XML doctype serialization when a system identifier contains a double quote, which could otherwise produce invalid XML. #2571
• XML serialization now repairs element and attribute names that start with an invalid character, rather than outputting null elements or dropping attributes. For example, an attribute named 1a is written as _1a. Additional leading underscores keep repaired attribute names unique if they conflict with another attribute. #2573
• Supplementary Unicode characters are now escaped correctly when serializing with non-UTF, non-ASCII output charsets such as ISO-8859-1. Previously, characters could be emitted unescaped when their low 16-bit value was representable by the configured charset, causing replacement or corruption when the output was encoded. #2578
• Fixed the JDK HttpClient implementation to accept responses missing a Content-Type header, matching the HttpURLConnection implementation. #2549
• Fixed HTTP response content-type matching to handle media types case-insensitively and recognize structured +xml suffixes, including vendor-specific media types. #2550
• HTTP request URL normalization now percent-encodes ASCII control characters, DEL, and embedded fragment delimiters, keeping normalized URLs valid for HTTP requests while preserving existing escapes. #2585
• Corrected multipart form encoding to percent-escape CR and LF in field names and filenames, matching the HTML form submission specification. Multipart file content-types containing CR or LF are now rejected with a ValidationException. #2555
• Aligned trailing comment placement with the HTML specification: comments after </body> remain children of the html element, while comments after </html> remain children of the document. #2557
• When using the optional re2j regular expression engine, memory allocation errors caused by complex selector patterns at match time are now normalized to a ValidationException with a Pattern complexity error message.
• Fixed parsing of malformed SVG and MathML content so that breakout HTML tags are placed according to the HTML specification. #2562
• Fixed deeply nested malformed HTML parsing that could lose the document body because stack lookups did not align to the configured maximum parser depth. #2569
• Aligned RCDATA, RAWTEXT, and script-data parsing with the HTML specification: malformed end tags no longer consume following markup, unclosed title/textarea content stays text through EOF, and custom text tags match exact names. #2577
• Improved URL validation during HTTP/HTTPS URL resolution and cleaning; resolved URLs without a host are now rejected instead of being accepted based only on their scheme prefix, aligning to RFC 9110. Valid relative links and non-HTTP(S) schemes are unchanged. #2579
• Redirects with malformed single-slash HTTP locations now use standard URL resolution to align with browsers. #2580
• Template fragment parsing now handles unmatched </template> tags without throwing a ValidationException. #2581
• Improved source tracking for adopted formatting elements and malformed markup ending at EOF. #2582
