Paul King updated GROOVY-11927:
-------------------------------
Description:
Add {{Node.toMap()}} for converting XML node trees to nested Maps, and
{{XmlParser.parseTextAs()}} / {{parseAs()}} for typed XML parsing via Jackson
databinding.
Three levels of support:
* `node.toMap()` — zero-dependency conversion to `Map<String, Object>`, usable
standalone
* `node as MyType` — coercion via `toMap()` + Groovy's named-param constructor
(works for String-typed properties, no additional deps)
* `parser.parseTextAs(Type, xml)` — full typed conversion (String→int, boolean,
etc.) plus `@JsonProperty`/`@JsonFormat` support; requires `jackson-databind`
at runtime, throws clear error if absent
Also adds {{XmlRuntimeException}} and an internal {{JacksonHelper}} utility
using reflective access to avoid a compile-time Jackson dependency on
{{groovy-xml}}.

static class ServerConfig {
String host

def config = new XmlParser().parseTextAs(ServerConfig, '''
<server>
<host>localhost</host>
<port>8080</port>
<debug>true</debug>

assert config instanceof ServerConfig
assert config.host == 'localhost'
assert config.port == 8080
