| description | Faithfully archive public WPS/KDocs/金山文档 links, especially embedded ProcessOn .pof mind maps and canvases, as raw source data, original SVG/PNG, and Markdown. Use when a user gives a kdocs.cn or wps.processon.com link and asks to scrape, save, download, 扒下来, 归档, or 转 Markdown without logging in or saving the document to an account. |
WPS Doc Scraper
Overview
Archive WPS/KDocs public documents with source fidelity. Prefer unauthenticated data APIs, keep the raw payloads, capture the original visual artifact when the document is a canvas or mind map, and generate Markdown only as a structured representation of the source.
This is an extraction skill, not a writing skill. Do not use an LLM to rewrite, summarize, smooth, or infer missing document content unless the user explicitly asks for a separate analysis after the archive is complete.
Workflow Decision Tree
-
Identify the URL type.
kdocs.cn/view/l/<share_id> or kdocs.cn/l/<share_id>: read public link metadata first.wps.processon.com/diagrams/view?...: extract file_id and group_id, then use the ProcessOn data API.wps.processon.com/wpsapi/diagrams/view/api?...: treat as the source API directly.- Other WPS/KDocs pages: collect public metadata, try official public export/download only when available, then use browser DOM capture as a fallback.
-
For ProcessOn .pof mind maps or canvases, run the API extractor:
python3 /path/to/wps-doc-scraper/scripts/wps_processon_extract.py \
--url "https://www.kdocs.cn/view/l/..." \
--output-dir "/path/to/archive-dir"
Expected outputs: processon-api.json, processon-definition.json, capture-manifest.json, and <title>.md.
-
Capture the original image.
- If the page exposes a rendered SVG, save the serialized full SVG as
<title>-全画布.svg.
- If the SVG uses
foreignObject, do not trust ImageMagick alone for text rendering. Use scripts/render_svg_tiles.py to make the PNG through macOS Quick Look square tiles.
python3 /path/to/wps-doc-scraper/scripts/render_svg_tiles.py \
--svg "/path/to/<title>-全画布.svg" \
--output "/path/to/<title>-全画布.png"
-
Validate the archive.
- Markdown is a structural conversion, not an editorial rewrite.
- The original image exists for visual documents.
- Raw JSON and manifest exist.
- No output text contains the Unicode replacement character
�.
- Any failed or permission-limited path is recorded in the manifest or final response.
Hard Rules
- Never log in, save to an account, copy into the user's cloud drive, or mutate the remote document unless the user explicitly requests it.
- Never bypass CAPTCHAs, paywalls, tenant restrictions, or permission walls. A public link that requires login is a hard boundary unless the user provides authorized access.
- Do not infer hidden nodes or missing text. Preserve what the API or rendered DOM actually exposes.
- HTTP 200 is not enough. Detect login-wall payloads such as
用户未登录, empty definitions, and placeholder shells.
- Keep raw source artifacts before transformation: API JSON, parsed definition JSON, serialized SVG, screenshots or PNGs, and a capture manifest.
- For browser fallback, capture DOM/source data before screenshots when possible; screenshots alone are not a faithful text archive.
- Report extraction gaps plainly. Do not silently produce a polished Markdown file from partial data.
Bundled Resources
scripts/
wps_processon_extract.py: deterministic extractor for public WPS/KDocs ProcessOn .pof mind maps. It resolves KDocs share metadata, downloads the ProcessOn data API JSON, parses the embedded definition, and writes Markdown plus a manifest.render_svg_tiles.py: macOS Quick Look based SVG-to-PNG renderer for full-canvas SVGs with foreignObject text. It renders square vertical tiles and stitches them into one PNG.
references/
processon-mindmap-api.md: endpoint pattern and payload shape for WPS-hosted ProcessOn files.rendered-svg-capture.md: browser-side process for extracting the rendered full-canvas SVG and producing a PNG.capture-manifest.md: minimum manifest fields and acceptance checks.permission-and-failure-boundaries.md: login walls, forbidden escalation, and failure reporting rules.
