分析带有自定义标记的txt文件

Question

我试图从EDGAR解析一个txt文件，但是不同的文件类型，有不同的格式的报告，即使它们都是txt文件。我可以使用BeautifulGroup解析xml报表，但是我遇到了这种类型的报表：

正如您所看到的，这个文件只是带有自定义标记的纯文本文件。在

我的问题是：如何在一个特定的标记中定位文本？例如，我只需要文本标签内的文本从上述文本文件。在

Answer 1

您可以选择文本标记，然后处理该内容：

soup = BeautifulSoup(open("/yourfile.html"), "html.parser")
text_tags = soup.find('text')
for text in text_tags:
    print text
    # work from here

注：我用了html.parser它已经返回了文本标记。如果更适合您的需要，您可能需要更改为xml解析器
