beautifulsoup .get_text（）不是对我的HTML解析不够具体 [英] beautifulsoup .get_text() is not specific enough for my HTML parsing

问题描述

由于HTML code下面我想输出H1的只是文本，但不是关于详情及NBSP;，这是跨度（这是由H1封装）的文本。

Given the HTML code below I want output just the text of the h1 but not the "Details about  ", which is the text of the span (which is encapsulated by the h1).

我的电流输出给：

Details about   New Men's Genuine Leather Bifold ID Credit Card Money Holder Wallet Black

我想：

New Men's Genuine Leather Bifold ID Credit Card Money Holder Wallet Black

这里是我一起工作的HTML

Here is the HTML I am working with

<h1 class="it-ttl" itemprop="name" id="itemTitle"><span class="g-hdn">Details about  &nbsp;</span>New Men&#039;s Genuine Leather Bifold ID Credit Card Money Holder Wallet Black</h1>

下面是我目前的code：

Here is my current code:

for line in soup.find_all('h1',attrs={'itemprop':'name'}):
    print line.get_text()

请注意：我不希望只是截断字符串，因为我想这code有一定的重复使用性。
什么是最好的一些code的出露由跨度为界的任何文本。

Note: I do not want to just truncate the string because I would like this code to have some re-usability. What would be best is some code that crops out any text that is bounded by the span.

推荐答案

您可以使用<一个href=\"http://www.crummy.com/software/BeautifulSoup/bs3/documentation.html#Removing%20elements\"><$c$c>extract()删除所有跨度标签：

for line in soup.find_all('h1',attrs={'itemprop':'name'}):
    [s.extract() for s in line('span')]
print line.get_text()
# => New Men's Genuine Leather Bifold ID Credit Card Money Holder Wallet Black
