Subgroup: Gml

Class: QgsGml

class qgis.core.QgsGml

Bases: PyQt5.QtCore.QObject

This class reads data from a WFS server or alternatively from a GML file. It uses the expat XML parser and an event based model to keep performance high. The parsing starts when the first data arrives, it does not wait until the request is finished *

disconnectNotify()

featuresMap(self) → object

Get parsed features for given type name

getFeatures(self, data: Union[QByteArray, bytes, bytearray], extent: QgsRectangle = None) → Tuple[int, QgsWkbTypes.Type]

Read from GML data. Constructor uri param is ignored Supports only UTF-8, UTF-16, ISO-8859-1, ISO-8859-1 XML encodings.

getFeaturesUri(self, uri: str, extent: QgsRectangle = None, userName: str = '', password: str = '', authcfg: str = '') → Tuple[int, QgsWkbTypes.Type]

Does the Http GET request to the wfs server Supports only UTF-8, UTF-16, ISO-8859-1, ISO-8859-1 XML encodings.

Parameters:

• uri – GML URL
• wkbType – wkbType to retrieve
• extent – retrieved extents
• userName – username for authentication
• password – password for authentication
• authcfg – authentication configuration id
