95af23d3a5 Forms: multi-select list values survive XML, CSV and text import (#5 )

Export data writes a multi-select list's values into one cell joined by ", " ("A, C"), but
import passed the cell on as a single choice, which the list refused, so the selection was
silently lost on an export → import round trip (the field was only counted as rejected).
A multi-select list now splits such a cell into its options, unless the whole cell is itself
one of them.

Forms: multi-select list values survive XML, CSV and text import (#5 )

2026-10-04 14:00:23 -04:00

Cargo.toml

M5.6/M6.7: Comment and form data exchange: new xfdf crate (L4): XFDF (ISO 19444-1) export/import of comments (replies, pop-ups, ink, quads, line ends, flags, colours) and nested field values; FDF both ways; form data as Acrobat XML, CSV and tab-delimited text. Import replaces comments with the same name and sets values through formats/validation (read-only fields take data). Import/Export commands; doc_export_data/doc_import_data tools (69 tools)

Layer L4: comment and form data exchange (execution plan M5.6, M6.7).

let xml = export_xfdf(&doc, true, true, "form.pdf");   // comments and/or field values
let fdf = export_fdf(&doc, false, true, "form.pdf");
let txt = export_data(&doc, Format::Txt);               // or Xml, Csv
let report = import(&mut doc, &bytes)?;                 // XFDF, FDF, XML, CSV or text, detected

XFDF (ISO 19444-1): every comment type PrintCraft knows (text, free text, line, square, circle, polygon, polyline, markup, stamp, caret, ink, attachments, sound, redact) with rect, name, author, subject, dates, flags, colours, opacity, width, icon, quads, line ends, ink, default appearance, pop-ups and reply threads (inreplyto); field values nested by name.
FDF: fields (with /Kids hierarchies) and comments as direct objects.
Form data: Acrobat's XML (xfdf:original keeps names that aren't XML names), CSV and tab-delimited text (a row of names, a row of values).

Import replaces comments with the same /NM, draws appearances PrintCraft can draw, and sets values through the form's own checks (formats, validation, recalculation); read-only fields take imported values, as in Acrobat. XML is read with roxmltree.
