mm include

Dieses Notebook:

• lese eine Freeplane-Mindmap ein

• für Text-Knoten, die mit “°i ” beginnen: lies die danach angegebene Mindmap ein

Beispiel

• Input: die Mindmap test.mm

• Output: die JSON-Datei test-included.mm

mm_path = "test.mm"

# wir verwenden die xml und xslt-Engine
# https://lxml.de/
from lxml import etree

    etree_tree = etree.parse(mm_path, parser)
    etree_startnode = etree_tree.getroot().find("node")
    return etree_tree, etree_startnode

included = [ mm_path ]
walk( etree_startnode, included)

included test2.mm: Root von test2
WARNING: rejecting multiple inclusion of test2.mm

['test.mm', 'test2.mm']

Wir schreiben das Ergebnis wieder ‘raus:

etree_tree.write(f"{mm_path}_included.mm", pretty_print=True)
