fix(slides): strip stale <note> id in +update-slide to avoid backend crash - #2475
Conversation
…crash A +update-slide carrying a <note id="..."> that is not the page's current note block makes RewriteSlideBySXSD reject the whole page with "block is not NoteBlock". This happens when the XML is copied from another page, or written over a page that was re-created (add-slide reassigns ids, so the note block's id no longer matches). Drop only the <note> id before sending. The backend then targets the page's own note block and the write succeeds. Every visible element keeps its id, so it is updated in place rather than rebuilt — text layout is preserved and there is no risk to svg-internal id references.

The note-id strip only matched id="...". A single-quoted or spaced form
(id='...', id = "...") slipped through. Both are valid XML, and the backend
accepts single-quoted markup — verified on ppe: an all-single-quote page
updates fine, and a single-quoted stale note id reproduces the exact
"block is not NoteBlock" crash this strip is meant to prevent, while the
double-quoted equivalent is stripped and succeeds.
Widen the regex to `\s+id\s*=\s*("[^"]*"|'[^']*')` so any quote style and
whitespace around '=' are covered. Still a targeted edit on the <note> tag,
not a re-serialization, so the caller's bytes are otherwise preserved.
Add regression cases: single quotes, whitespace around '=', single-quote
attribute order, and a single-quoted visible-element id left untouched.

removed. Preserve all other XML bytes and leave comments, CDATA, quoted
attribute content, and unrelated attributes unchanged; add regression coverage
for these cases while maintaining the existing output contract.

The strip tests checked that a specific id value ("blw") disappeared, which
would also pass if the implementation swapped the id for another value.
Assert on the <note> opening tag carrying no id attribute at all (any quote
style / spacing) via a noteTagHasID helper, so the removal itself is verified.
Addresses CodeRabbit review on #2475.
…pping id The raw regex parsed XML as plain text, so it could miss or mis-edit valid input: an id after an attribute whose value contains '>', and note-like text inside comments or CDATA. It also had no notion of where the note sat in the tree. Walk the document with encoding/xml to find the start tag of the <note> that is a direct child of the root <slide>, then delete the id attribute by editing only that tag's bytes. Nothing is re-serialized, so quote style, attribute order, whitespace, and every other element (notably inline <svg> namespaces, whose round-tripping is a known source of "embed missing inner svg") survive untouched — the same byte-preservation contract ensureXMLRootID keeps. This covers the cases the regex could not: '>' in an attribute value, and comment/CDATA text that merely looks like a <note>; and it scopes the edit to the slide-level note only. Regression cases added for each. Addresses CodeRabbit review on #2475.
Existing tests spot-checked that individual elements survived. Add exact-equality cases asserting the output equals the input with only the one note id removed — proving nothing else moves: inline svg subtrees, CDATA, a '>'-bearing attribute, quote style, attribute order, and whitespace all stay verbatim. Addresses CodeRabbit review on #2475.

LGTM. Verified the XML span-based edit preserves numeric character references and other untouched source bytes; targeted Slides tests and go vet pass.

slides +update-slide提交的 XML 里如果带了一个不属于当前页的<note id="...">,后端会用block is not NoteBlock拒绝整页更新复现场景:
+add-slide会重新分配 id),原来的 note id 已经失效后端
RewriteSlideBySXSD拿这个 stale 的 note id 去定位 note block,定位到的不是 NoteBlock,于是整页更新失败。修复
在发送前只去掉
<note>元素上的id属性(stripSlideNoteID)。没有 id 时后端会定位到本页自己的 note block 并原地改写,更新成功。为什么只去 note 的 id、保留其他所有元素的 id:
url(#id)/href="#..."这类文档内引用。验证
单测:
TestStripSlideNoteID(note id 被删,shape/embed/svg 的 id 及url(#grad)/href="#pp"全部保留)、无 note 直通、属性顺序三个用例。go test ./shortcuts/slides/通过,go vet无告警。线上 A/B 对比,把 A 页 XML(带 stale note id)应用到 B 页:
