Ich befinde mich in der unglücklichen Situation ein Python-Skript anpassen zu müssen, ohne den Drang ein Profi in Python-Programmierung werden zu wollen. Ich bin schon recht weit gekommen, aber bei einer Sache komme ich einfach nicht weiter und hoffe hierbei nun auf Hilfe. Ich habe auch keine Ahnung, ob der Titel überhaupt stimmt, da ich mein Problem nicht einmal ganz einordnen kann und die richtigen Begriffe nicht kenne.
Problem kurz angerissen: Ich möchte auf ein spezifisches Element eines Arrays zugreifen, jedoch haben mehrere Elemente den gleichen Namen und ich bekomme nur den Wert des ersten. Ich möchte an die Werte der Tags <comment /> in der XML-Datei (siehe unten) kommen.
Um meinen Wissensstand einordnen zu können, kurz zu meiner Person: Ich habe Assambler, C, C++ und Python beiläufig im Studium gehabt, verstehe was von C und C++, aber habe mir Programmierung mehr selbst beigebracht, als dass ich es richtig gelernt hätte.
Worum geht es? Ich nutze die Software KiCAD (Software zum Erstellen von Platinen). Die Software erzeugt eine XML-Datei aus dem Schaltplan und generiert daraus mittels Python-Skript eine CSV-Datei, die dann die gewünschten Informationen enthält. Dieses Skript möchte ich anpassen und habe es auch größtenteils schon geschafft, nur auf eine Information kann ich einfach nicht zugreifen. Hier habe ich offenbar ein Verständnisproblem.
Ich verwende PyCharm als IDE. Das Skript heißt "bom_csv_grouped_by_value.py". Das Skript habe ich auf das Wesentliche (für das Problem) reduziert unten angefügt. Das Meiste passiert in "kicad_netlist_reader.py", vollständig angefügt. Auf Wunsch kann ich auch eine ZIP hochladen, die alles enthält.
In den meisten Fällen sah es im Skript so aus, dass eine Klasse einzelne Attribute hat, die vershachtelte Arrays sind. Ein Attribut heißt "element". Auf die verschachtelten Elemente (in PyCharm immer als "children" bezeichnet, ich nenne es daher mal Kind) greife ich mit der Methode get() zu, der ich mit Kommata getrennt die Kind-Namen übergebe, zum Beispiel so: self.element.get("field", "name", "Hersteller")
"element" hat das Kind "field", das wiederum das Kind "name" und das wiederum "Hersteller". Den Wert von diesem Kind-Element bekomme ich als Rückgabewert. Dass ich über Kommata getrennt auf untergeordnete Kind-Elemenze zugreifen kann, konnte ich im Internet so nicht finden, aber im Original-Skript wurde das so gemacht. Manchmal klappte das nicht, da brauchte ich die Methode getChild(), obwohl die Struktur und Darstellung für mich im PyCharm-Debugger gleich aussieht. Das akzeptiert auch nur einen Übergabewert. Kann ich mir bisher nicht erklären. Wenn es nicht zu umfangreich ist, wäre ich hier für eine Erklärung dankbar, auch wenn das eventuell nichts mit dem Pronlem zu tun hat.
Die Klasse "netlist" hat ein Attribut "design", das ein Array ist und der Struktur der XML-Datei entspricht. Das <design>-Tag enthält den Tag <sheet>, das den Tag <title_block> und das wiederum unter anderem die <comment />-Tags, die mich interessieren. Wie in dem Skript "bom_csv_grouped_by_value.py" zu sehen ist, musste ich mir hier damit helfen die Methode getChild() zu benutzen, um an das Array "sheet" zu kommen und dann erneut die gleiche Methode, um an das darin enthaltene Array "title_block" zu kommen. Das speichere ich in "sheet", siehe Bild.
Ich kann mit sheet.get() auf die Elemente title, company, rev, date und source zugreifen, nicht aber auf die Elemente mit dem Namen "comment". Dafür brauche ich wieder getChild(). Versuche ich den Wert des Attributs "value" mit c1.get_attribut("value") zu bekommen, wird mit der Fehler angezeigt, c1 hätte das Attribut "value" gar nicht. Ich komme da einfach nicht weiter. Hilfe!
