v1.0.2

Fixes

Most of these were reported in #3 and #4.

Parsing

• A stray quote in a tag, like <a href="/x"">, no longer turns the rest of the page into text. Tags follow the attribute rules of htmlparser2: a quote starts a value only after =. (877ff5a)
• An unquoted value can end with /, so <svg><path d=M0/> is not self-closing, like in htmlparser2 and browsers. (877ff5a)
• The tokenizer follows browsers at the edges: (e1f66fb)
  • An unfinished tag at the end of the source is dropped, not kept as text.
  • Only <!doctype …> is a directive. Other <!…> markup is a comment.
  • <![CDATA[…]]> is text inside <svg> and <math>.
  • <!--> and <!---> are empty comments, and --!> ends a comment.
• Inside <svg>, the text of <style> is decoded like normal text, because it is not raw text there. (f816928)
• Selectors skip the contents of <template>, like css-select. (6c0340a)

@lukeed/html/mutable

• An edited self-closing tag, like <path/> in SVG, keeps its />. If it gets children, it gets an end tag. (95c4a98)
• A rebuilt tag copies its unedited attributes as written, so viewBox stays viewBox and © stays ©. An edited attribute keeps its name as written. A new attribute is written as given to setAttr(). (b56b76a, 744e073)
• An element without an end tag in the source, like <li> without </li>, gets one when an edit moves what closed it. Before, nodes inserted after it ended up inside it. (bed2162)
• Text that moves into or out of <script>, <style>, or <title> is escaped for its new parent. (bd54bf7)
• The html setter parses in the context of the element, so svg.html = "<path/><path/>" gives two paths. (f816928)

Features

• clone() on Element, Text, Comment, and Directive in @lukeed/html/mutable. (07966a0)
• A name setter on Element in @lukeed/html/mutable, to rename an element. (1dd6b37)
• Document.text, in both modules. (7a95b39)

Performance

Edits are faster. Results on 12 real pages (4.79 MB), with Bun 1.4.4 and Node 26.12.1 on an Apple M1 Max:

Workload	Bun	Node
mutable parse + edit + stringify	27.8ms → 20.7ms	35.5ms → 28.3ms

When an edit only adds attributes, the tag is copied from the source and the new attributes are added at the end, so the other values are not escaped again. (744e073) On pages with <template>, part of the gain comes from selectors that now skip template contents.

Other workloads are within a few percent of 1.0.1, and memory is the same. (89bd48a, c6ff936, 8faf3f9)

Notes

• Some output changes:
  • <!x> and similar markup are now Comment nodes, not Directive nodes.
  • The value of a <?…> comment now starts with ?, like in browsers.
  • In a rebuilt tag, an empty attribute value is written as name="".
  • The comment and directive setters throw for a value that would not parse back to the same node.
• The bundle is larger: 6.3 kB gzip for @lukeed/html (was 5.9 kB) and 8.8 kB for @lukeed/html/mutable (was 7.1 kB).
