XmlError

pub suberror XmlError {
  Parse(String, Int, Int)
}

Internal parser error carrying the source position.

Document

source

pub struct Document {
  nodes : Array[Node]
  root_id : Int?
}

A parsed XML document.

Document::add_attribute

source

fn Document::add_attribute(self : Document, element : Int, name : QName, value : String) -> Int

Append an attribute node to an element.

Attribute ids are ordered by declaration and share the document-order key of their element.

Append a comment node under parent.

Document::add_element

source

fn Document::add_element(self : Document, parent : Int, name : QName) -> Int

Append a new element node under parent and return its id.

Used by the parser and by result-tree construction in the XSLT engine.

fn Document::add_processing_instruction(self : Document, parent : Int, target : String, data : String) -> Int

Append a processing-instruction node under parent.

Document::add_raw_text

Append a text node whose content is written without escaping, for disable-output-escaping="yes".

Document::add_text

source

fn Document::add_text(self : Document, parent : Int, text : String) -> Int

Append a text node under parent.

Adjacent text nodes are merged, as required by the XPath data model; in that case the existing node id is returned.

Ancestors of a node, nearest first.

Document::ancestors_or_self

fn Document::attribute_by_expanded(self : Document, element : Int, uri : String, local_part : String) -> Int?

Look up an attribute by expanded (uri, local_part) name.

Document::attribute_by_local

source

fn Document::attribute_by_local(self : Document, element : Int, local_part : String) -> Int?

Look up an attribute by local_part name, ignoring the namespace.

Document::attribute_value

source

fn Document::attribute_value(self : Document, element : Int, local_part : String) -> String?

Look up an attribute value by local_part name.

Child node ids of a document or element node, in document order.

Document::compare_order

source

fn Document::compare_order(self : Document, a : Int, b : Int) -> Int

Compare two node ids in document order.

Returns a negative number when a precedes b, zero when they are the same node, and a positive number otherwise.

Descendants of a node in document order, including the node itself.

Document::document_order

source

fn Document::document_order(self : Document, id : Int) -> Int

Document-order key of a node.

Nodes are numbered in document order, except that attributes reuse the order key of their owning element so that a sort on (order, id) yields element, then its attributes, then its children.

Document::import_subtree

source

fn Document::import_subtree(self : Document, parent : Int, source : Document, node : Int) -> Int

Copy a subtree from another document under parent.

Names are already resolved in the source document, so the copy keeps the resolved names, the namespace declarations and the text escaping flags. Returns the id of the copied node, or parent for node kinds that cannot be copied (document and attribute nodes).

Document::index_in_parent

source

fn Document::index_in_parent(self : Document, id : Int) -> Int?

source

fn Document::name(self : Document, id : Int) -> QName?

The expanded name of an element or attribute node.

Document::namespace_declarations

source

Namespace declarations attached to an element, as (prefix, uri) pairs.

The empty prefix denotes the default namespace.

Document::namespace_uri

The namespace URI of an element or attribute name, "" when unqualified.

Document::node_count

source

fn Document::node_count(self : Document) -> Int

Document::nodes_in_document_order

source

fn Document::nodes_in_document_order(self : Document) -> Array[Int]

Document::to_xml

source

fn Document::to_xml(self : Document, indent? : Bool, declaration? : Bool) -> String

source

pub(all) enum NodeKind {
  Document
  Element
  Attribute
  Text
  Comment
  ProcessingInstruction
}

The six node kinds of the XPath 1.0 data model.

Namespace nodes are not materialised: the namespace axis is derived from the declarations stored on element nodes.

QName

  prefix : String
  local_part : String
  uri : String
}
