jsoup Java HTML Parser release 1.15.4

2023-Feb-18

jsoup 1.15.4 is out now, and includes a bunch of improvements, particularly when pretty-printing HTML, and bug fixes.

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

Improvements

Added the ability to escape CSS selectors (tags, IDs, classes) to match elements that don't follow regular CSS syntax. For example, to match by classname <p class="one.two">, use document.select("p.one\\.two"); #838

When pretty-printing, wrap text that follows a <br> tag. #1858

When pretty-printing, normalize newlines that follow self-closing tags in custom tags. #1852

When pretty-printing, collapse non-significant whitespace between a block and an inline tag. #1802

In Element.forEach() and Node.forEachNode(), use java.util.function.Consumer instead of the previous Android compatibility shim org.jsoup.helper.Consumer. Subsequently, the latter has been deprecated. #1870

Added a new method Document.forms(), to conveniently retrieve a List<FormElement> containing the <form> elements in a document.

Added a new method Document.expectForm(), to find the first matching FormElement, or blow up trying.

Bug Fixes

URLs containing characters such as and <code> were not escaped correctly, and would throw a MalformedURLException when fetched. #1873

Element.cssSelector() would create invalid selectors for elements where the tag name, ID, or classnames needed to be escaped (e.g. if a class name contained a : or .). #1742

Element.text() should have a space between a block and an inline element. #1877

If a Node or an Element was replaced with itself, that node would incorrectly be orphaned. #1843

Form data on a previous request was copied to a new request in newRequest(), resulting in an accumulation of form data when executing multi-step form submissions, or data sent to later requests incorrectly. Now, newRequest() only copies session related settings (cookies, proxy settings, user-agent, etc) but not the request data nor the body. #1778

Fixed an issue in Safelist.removeAttributes() which could throw a ConcurrentModificationException when using the :all pseudo-attribute.

Given extremely deeply nested HTML, a number of methods in Element could throw a StackOverflowError due to excessive recursion. Namely: #data(), #hasText(), #parents(), and #wrap(html). #1864

Changes

Deprecated the unused Document.normalise() method. Normalization occurs during the HTML tree construction, and no longer as a distinct phase.
