Question

好的我正在尝试使用python beautiful soup从下面的html中选择文本数据，但我遇到了麻烦。基本上<b>中有一个标题，但我想要除此之外的数据。例如，第一个是评估类型，但我只想要容量曲线。以下是我到目前为止的情况：

modelinginfo = soup.find( "div", {"id":"genInfo"} ) # this is my raw data
rows=modelinginfo.findChildren(['p']) # this is the data displayed below
for row in rows:
    print(row)
    print('/n')
    cells = row.findChildren('p')
    for cell in cells:
         value = cell.string
         print("The value in this cell is %s" % value)

Answer 1

1。）您可以迭代p children并打印所有内容，但b代码除外：

for cell in cells:
    for element in cell.children:
        if element.name != 'b':
            print("The value in this cell is %s" % element)

2。）您可以使用extract()方法为b标记清除不需要的内容：

for cell in cells:
    if cell.b:
        # remove "b" tag
        cell.b.extract()
    print("The value in this cell is %s" % cell)
