我有以下 HTML 文件，其中包含bbox來自 PDF 文件的信息：<flow> <block xMin="53.879997" yMin="369.965298" xMax="63.939976" yMax="380.991433"> <line xMin="53.879997" yMin="369.965298" xMax="63.939976" yMax="380.991433"> <word xMin="53.879997" yMin="369.965298" xMax="63.939976" yMax="380.991433">10</word> </line> </block></flow><flow> <block xMin="53.879997" yMin="417.965298" xMax="63.939976" yMax="428.991433"> <line xMin="53.879997" yMin="417.965298" xMax="63.939976" yMax="428.991433"> <word xMin="53.879997" yMin="417.965298" xMax="63.939976" yMax="428.991433">20</word> </line> </block></flow><flow> <block xMin="111.351361" yMin="369.965298" xMax="134.220382" yMax="380.991433"> <line xMin="111.351361" yMin="369.965298" xMax="134.220382" yMax="380.991433"> <word xMin="111.351361" yMin="369.965298" xMax="116.331548" yMax="380.991433">1</word> <word xMin="121.909358" yMin="369.965298" xMax="134.220382" yMax="380.991433">PC</word> </line> </block></flow>以上是單詞的邊界框區域：10 20 1 PC在原始文檔中，是這樣寫的：10 1 PC20因此，我想解析上面的 HTML 文件并提取所有 <line>標簽，然后按yMin值對它們進行排序。上面的最終輸出將是：10 1 PC 20而不是。到目前為止我嘗試過的我不是很遠，因為我還在學習 Python。我正在使用 BeautifulSoup4：with open("test.html", "r") as f: contents = f.read() soup = BeautifulSoup(contents, 'lxml') for line in soup.find_all("line", attrs={"ymin":True}): print(line.get('ymin'))上面只是打印出每個標簽及其內容。我不確定如何對行標簽進行排序。任何幫助將不勝感激。

您可以BeautifulSoup使用soup.find_all：
from bs4 import BeautifulSoup as soup
r = [i.find_all('word') for i in sorted(soup(html, 'html.parser').find_all('line'), key=lambda x:float(x['ymin']))]
result = [i.text for b in r for i in b]
輸出：
['10', '1', 'PC', '20']

試試下面的代碼?？梢远x平均值，然后檢查平均值。

soup=BeautifulSoup(html,'lxml')

else:

print(list1+list_last)
輸出：

打印這個
print(' '.join(list1+list_last))
輸出：
