Struct XmlElement 

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

A single XML element per §7.1.4 / §7.1.5 (element + attributes).

Fields

name: String

Local tag name (without the namespace prefix).

namespace: Option<String>

Optional namespace URI per §7.1.3.

attributes: BTreeMap<String, String>

Attributes (name -> value, alphabetically sorted via BTreeMap for deterministic iteration).

children: Vec<XmlElement>

Child elements in document order.

text: String

Direct text content (contiguous text part immediately before the first child element). Empty if no text is present.

Implementations

impl XmlElement

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

Returns the first child with the given local name, if present.

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

Returns all children with the given local name.

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

Returns the value of an attribute, if present.

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

Iterates over <element> children per Spec §7.2.4.1 (IDL sequence mapping) and §7.2.5 (IDL array mapping = sequence mapping with the same 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.” — i.e. the <element> tag is also used for arrays.

Used by the IDL-PSM mapping (qos_parser, sample) to iterate generic sequences/arrays.

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 Eq for XmlElement

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.
