XmlNode

class xsdata.formats.dataclass.parsers.nodes.XmlNode[source]

The xml node interface.

The nodes are responsible to find and queue the child nodes when a new element starts and build the resulting object tree when the element ends. The parser needs to maintain a queue for these nodes and a list of all the intermediate object trees.

abstract child(qname, attrs, ns_map, position)[source]

Initialize the next child node to be queued, when a new xml element starts.

This entry point is responsible to create the next node type with all the necessary information on how to bind the incoming input data.

Parameters
  • qname (str) – Qualified name

  • attrs (Dict) – Attribute key-value map

  • ns_map (Dict) – Namespace prefix-URI map

  • position (int) – The current objects position, to mark future objects as children

Return type

XmlNode

abstract bind(qname, text, tail, objects)[source]

Build the object tree for the ending element and return whether the result was successful or not.

This entry point is called when an xml element ends and is responsible to parse the current element attributes/text, bind any children objects and initialize new object.

Parameters
  • qname (str) – Qualified name

  • text (Optional[str]) – Text content

  • tail (Optional[str]) – Tail content

  • objects (List) – The list of intermediate parsed objects, eg [(qname, object)]

Return type

bool
