原标题:Beautifulsoup navigating divs by attribute without findAll

How do I find a specific div by calling the attributes of a soup? i.e. something like soup.html.body.div however I don t see how to get the specific div with id= idname here?

我可以做以下工作:soup.findAll(id=idname )[0],以获得具体标签,但我的理解是,这正在寻找整个电梯。

I imagine getting the div by attribute on the soup would be faster since you are not using findAll()?

消防局报告,地点为html. . . .div/ form.table/ table/12.t .tr[3]然而,在soup.html. . . . . .andiv/ <上留下了重大错误。

<>条码>html/上/上/上/上/上/上/上/上/上/上/上/上[3]/div[3]/上/上/上/英寸>

使用<条码>限值的 所有?

最佳回答

你们从火焰中走的道路是XPath。 最好使用允许你直接使用xpath的教区。 我愿使用<条码>lxml及其<条码>。

from lxml import etree
tree = etree.parse(yourfile)
lucky = tree.xpath( /html/body/center/span/center/div[2]/form/div[2]/div[3]/center/input[2] )
问题回答

采用<条码>定型儿童方法,其方式大部分。

相当于:

findAll(tagname, recursive=False)

这通常会使其更有效率。

因此,你的例子将变成:

soup.html.body.center.span.center.findChildren( div )[2].
    form.findChildren( div )[2].findChildren( div )[3].
    center.findChildren( input )[2]
