Struct XmlElement 

pub struct XmlElement {
    pub name: String,
    pub namespace: Option<String>,
    pub attributes: BTreeMap<String, String>,
    pub children: Vec<XmlElement>,
    pub text: String,
}

Ein einzelnes XML-Element nach §7.1.4 / §7.1.5 (Element + Attribute).

Fields

name: String

Lokaler Tag-Name (ohne Namespace-Prefix).

namespace: Option<String>

Optionaler Namespace-URI gemaess §7.1.3.

attributes: BTreeMap<String, String>

Attribute (Name -> Wert, alphabetisch sortiert via BTreeMap fuer deterministische Iteration).

children: Vec<XmlElement>

Kind-Elemente in Dokument-Reihenfolge.

text: String

Direkter Text-Inhalt (zusammenhaengender Text-Teil unmittelbar vor dem ersten Kind-Element). Leer wenn kein Text vorhanden.

Implementations

impl XmlElement

pub fn child(&self, name: &str) -> Option<&XmlElement>

Liefert den ersten Kind mit dem gegebenen lokalen Namen, falls vorhanden.

pub fn children_named<'a>( &'a self, name: &'a str, ) -> impl Iterator<Item = &'a XmlElement> + 'a

Liefert alle Kinder mit dem gegebenen lokalen Namen.

pub fn attribute(&self, name: &str) -> Option<&str>

Liefert den Wert eines Attributs, falls vorhanden.

pub fn sequence_elements(&self) -> impl Iterator<Item = &XmlElement> + '_

Iteriert ueber <element>-Kinder gemaess Spec §7.2.4.1 (IDL-Sequence-Mapping) und §7.2.5 (IDL-Array-Mapping = Sequence- Mapping mit gleichem Element-Tag).

Spec OMG DDS-XML 1.0 §7.2.4.1: “The complexType contains zero or more elements named element. Nested inside each element is the XSD schema obtained from mapping the IDL type of the element itself.”

Spec §7.2.5: “The XML representation of IDL arrays is the same as it would be for IDL sequences of the same element type.” — d.h. <element>-Tag wird auch fuer Arrays genutzt.

Wird vom IDL-PSM-Mapping (qos_parser, sample) genutzt, um generische Sequenzen/Arrays zu iterieren.

Trait Implementations

impl Clone for XmlElement

fn clone(&self) -> XmlElement

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for XmlElement

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for XmlElement

fn default() -> XmlElement

Returns the “default value” for a type.

impl PartialEq for XmlElement

fn eq(&self, other: &XmlElement) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
