How do I parse XML in Zig?

With serde.zig: serde.xml.fromSliceManaged(User, allocator, input). The root element is matched against .xml_root.

Are XML namespaces supported?

Prefixed names are kept as the wire names serde.zig matches, and xmlns declarations are ignored rather than turned into fields.

XML to Zig struct

Paste an XML document and zigshape produces Zig structs with xml_root and xml_attribute decoration for serde.zig.

API responseSmallest int widths from observed range; auto enum suggestion; missing/null become optional.

Upload

<user id="42">
  <name>Alice</name>
  <role>admin</role>
</user>

User.zig

const serde = @import("serde");

pub const User = struct {
    name: []const u8,
    role: []const u8,
    id: u8,

    pub const serde = .{
        .xml_root = "user",
        .xml_attribute = .{ .id },
    };
};

Field decisions

Why each field got its type. Click a row to see it in the input; edit to override.

struct User $ 3 fields

What zigshape does with XML

Attributes are listed in .xml_attribute; child elements become fields.
Namespace prefixes stay on the wire: soap:Body becomes a body field with .rename.
Text is typed as a number only when it parses back (2.0 is a float, 02134 stays a string).
Text inside an element that also has attributes becomes an optional value field, because serde.zig skips that text.
