Parsing Data-Bind-Tag in HTML mit Beautiful Soup

Question

Ich habe Probleme bei der Auswahl dieses "Div" -Objekt in Beautiful Soup und dann analysieren die Daten darin.

Zuerst muss ich die HTML-Entitäten wie die Funktion auf dieser Website (https://mothereff.in/html-entities) dekodieren.

Welche Schritte würde ich nehmen, um zum Beispiel programmatisch wählen

(Grösse: '/ s3/fhphotos/CIRD-72K6-H9_SID_1.jpg, Breite = 1000 & height = 1000 & mode = max')

aus dem Code unten

Answer 1

Es ist nicht ganz klar, wo diese HTML-String herkommt und was genau sind Sie bei der Gewinnung interessiert, sondern auch für die schöne Suppe Teil, den Sie brauchen einfach:

soup = BeautifulSoup(s) 
text = soup.div['data-bind'] 

wo s die Zeichenfolge in Ihrer Frage ist . Wir bekommen zuerst das 'div' tag, bevor wir die 'Datenbindung' attribute bekommen.

Das Format verwirrt mich wie es ist ähnlich wie json und ähnlich wie ein Python-Wörterbuch, aber keiner dieser Parser mochte die Eingabe. Ich schätze sein Javascript? Ich schrieb eine schnelle und schmutzige Schleife Klammer Zählen von diesen question inspiriert:

nest_lvl = 0 
lvl_string = list() 
for char in text: 
    if char == '{': 
     nest_lvl += 1 
    elif char == '}': 
     nest_lvl -= 1 

    try: 
     lvl_string[nest_lvl] += char 
    except IndexError:   # first iter 
     lvl_string.append(char) 

    if char == '}': 
     print nest_lvl, lvl_string[nest_lvl] 
     lvl_string[nest_lvl] = '' 

, die hoffentlich werden Sie den Start. Auch hier hängt der Parsing-Teil davon ab, wie allgemein der Parser sein muss und was genau Sie extrahieren wollen.
