From: Lady Date: Sun, 14 Apr 2024 19:44:22 +0000 (-0400) Subject: Add support for manually serializing X·M·L X-Git-Tag: 0.7.2~1 X-Git-Url: https://git.ladys.computer/Shushe/commitdiff_plain/3dc36d1f23aff7cb60b498d88e503b619a7bc543?ds=sidebyside Add support for manually serializing X·M·L This commit adds a transform for a new `<书社:serialize-xml>` element, which is useful in conjunction with `<书社:raw-text>` to produce a more finely‐controlled X·M·L output, or in other X·M·L‐y situations where an escaped X·M·L value is required. The algorithm used for serialization attempts to closely match the DOM Parsing and Serialization spec, including such behaviours as mandating an undeclared `xml:` prefix for the X·M·L name·space and dropping the prefix from elements whose name·space matches the default, but it probably isn’t exactly the same (due in part to the fact that the underlying data structure is an X·M·L infoset, not a potentially dynamically‐modified Dom). No special allowances are made for elements in the H·T·M·L name·space; this is not (yet) a suitable polyglot serializer (or intended to be one). --- diff --git a/README.markdown b/README.markdown index 55d6f8f..643a4d8 100644 --- a/README.markdown +++ b/README.markdown @@ -87,19 +87,23 @@ As this is a Make‐based program, steps will only be run if the corresponding buildfile or output file is older than its prerequisites. -## Namespaces +## Name·spaces -The ⛩️📰 书社 namespace is `urn:fdc:ladys.computer:20231231:Shu1She4`. +The ⛩️📰 书社 name·space is `urn:fdc:ladys.computer:20231231:Shu1She4`. -This document uses a few namespace prefixes, with the following +This document uses a few name·space prefixes, with the following meanings :⁠— -| Prefix | Expansion | -| -------: | :----------------------------------------- | -| `html:` | `http://www.w3.org/1999/xhtml` | -| `xlink:` | `http://www.w3.org/1999/xlink` | -| `xslt:` | `http://www.w3.org/1999/XSL/Transform` | -| `书社:` | `urn:fdc:ladys.computer:20231231:Shu1She4` | +| Prefix | Expansion | +| ---------: | :-------------------------------------------- | +| `catalog:` | `urn:oasis:names:tc:entity:xmlns:xml:catalog` | +| `exsl:` | `http://exslt.org/common` | +| `exslstr:` | `http://exslt.org/strings` | +| `html:` | `http://www.w3.org/1999/xhtml` | +| `svg:` | `http://www.w3.org/2000/svg` | +| `xlink:` | `http://www.w3.org/1999/xlink` | +| `xslt:` | `http://www.w3.org/1999/XSL/Transform` | +| `书社:` | `urn:fdc:ladys.computer:20231231:Shu1She4` | ## Setup and Configuration @@ -293,7 +297,7 @@ New ⛩️📰 书社 parsers which target plaintext formats should have an `` element with no `@name` or `@mode` and whose `@match` attribute… -- Starts with an appropriately‐namespaced qualified name for a +- Starts with an appropriately‐name·spaced qualified name for a `` element. - Follows this with the string `[@type=`. @@ -350,7 +354,7 @@ Parsers are applied *prior* to embedding (and can be used to generate embeds); transforms are applied *after*.
