问题
I am trying to process text files like this one:
http://www.sec.gov/Archives/edgar/data/789019/000119312514289961/0001193125-14-289961.txt
If you see around the middle of the file there is something like the following:
</TEXT>
</DOCUMENT>
<DOCUMENT>
<TYPE>EXCEL
<SEQUENCE>21
<FILENAME>Financial_Report.xlsx
<DESCRIPTION>IDEA: XBRL DOCUMENT
<TEXT>
begin 644 Financial_Report.xlsx

This seems like an excel file ? Or an XBRL document ? What is that ? How do I get rid of it (or "process" it somehow??) This goes on for thousands of lines so I guess it is some encoding of some link of some attached file?? Any idea how to deal with it ?
I am trying to use BeautifulSoup in Python:
from bs4 import BeautifulSoup
with open("textWithHtml.txt") as markup:
soup = BeautifulSoup(markup.read())
with open("processedText.txt", "w") as f:
f.write(soup.get_text().encode('utf-8'))
but not everything is removed, and also I noticed that in some cases not even all html tags are removed.. sometimes running the code twice removes more than what were removed the first time the BeautifulSoup code was run..
回答1:
The encoding you are looking at is uuencode. In Python, you would use the uu module to decode this blob, or simply stringdata.decode('uu').
uuencode is a legacy format which was originally used to embed binaries in email (which then only permitted 7-bit US-ASCII; the format also has some concessions for interoperability with big-iron systems of the day which used their own bewildering character encodings). These days, you would expect to see base64 in this role.
I posted an answer to the followup question which shows how to remove uuencode blobs while reading from a filehandle or iterating over a bunch of lines of text.
回答2:
The problem can efficiently be solved using the sed command as provided here : sed command - apply in all text (.txt) files of folder
