Príklady použitia

Prečítajte nadpis stránky 

from aspose.note import Document, Page

doc = Document("MyNotes.one")
for page in doc.GetChildNodes(Page):
    title = page.Title
    if title and title.TitleText:
        print("Title:", title.TitleText.Text)
    if title and title.TitleDate:
        print("Date:", title.TitleDate.Text)
    if title and title.TitleTime:
        print("Time:", title.TitleTime.Text)

Pomocník pre bezpečné získavanie nadpisu 

from aspose.note import Document, Page

def get_title(page: Page) -> str:
    if page.Title and page.Title.TitleText:
        return page.Title.TitleText.Text
    return "(untitled)"

doc = Document("MyNotes.one")
for page in doc.GetChildNodes(Page):
    print(get_title(page))

Získajte uzol nadpisu pomocou GetChildNodes

Title je skutočný podriadený uzol v Page podstrome, takže ho možno nájsť pomocou GetChildNodes:

from aspose.note import Document, Page, Title

doc = Document("MyNotes.one")
for page in doc.GetChildNodes(Page):
    titles = page.GetChildNodes(Title)
    if titles:
        t = titles[0]
        print("TitleText:", t.TitleText.Text if t.TitleText else None)

Použite návštevníka na zhromaždenie textu nadpisu 

from aspose.note import Document, DocumentVisitor, Title

class TitleCollector(DocumentVisitor):
    def __init__(self):
        self.titles = []

    def VisitTitleStart(self, title: Title) -> None:
        if title.TitleText:
            self.titles.append(title.TitleText.Text)

doc = Document("MyNotes.one")
collector = TitleCollector()
doc.Accept(collector)
print(collector.titles)

Bezpečnosť pri None

page.Title sám môže byť None pre stránky bez metadát názvu. TitleDate a TitleTime sú None keď nie je prítomné. Vždy chráňte:

text = page.Title.TitleText.Text if page.Title and page.Title.TitleText else ""
