ancXmlAttribute: xml element um Attribut erweitern

was macht diese Extension und wodurch zeichnet sie sich aus

• diese extension ist Beispielhaft und minimal
• sie soll ein ausgewähltes Element einfach ein Attribut anfügen und einen übergebenen wert zuweisen

folgende links haben mir dabei geholfen

• Write an Inkscape extension: create multiple duplicates
• 19.7. xml.etree.ElementTree — The ElementTree XML API
• PythonEffectTutorial

Installation

• damit sie läuft müssen folgende beiden Dateien in eines von den beiden Verzeichnissen kopiert werden
  • /usr/share/inkscape/extensions/
  • .config/inkscape/extension/
