Question

我尝试从.doc文件中提取文本。提取了文本，但问题是它始终输出：

ࡱ ＆gt; ln字符。

这是我的代码：

    doc=open(input_file,'r')
    read_text_file = doc.readline()
    doc_text = ""
    for line in read_text_file:
        doc_text+=str(line)

    return doc_text

有没有办法将其删除或重新编码为utf-8？

docx文件只是一个zip文件（尝试在其上运行解压缩！），其中包含一堆定义良好的XML和附属文件。

import zipfile
from lxml import etree

def get_word(docx_file_name):
    with open(docx_file_name) as f:
        zip = zipfile.SipFile(f)
        xml_content = zip.read('word/document.xml')
return xml_content

#parse the string containing XML into a usable tree
def get_xml_tree(xml_string):
    return etree.fromstring(xml_string)
#xml has functions for traversing the XML tree, but I used the iter instead that 
#will traverse every node given a starting node ”my_etree”, and return every 
#text node and it’s containing text
def _itertext(self, myetree):
    """goes through the xml tree and extracts nodes"""
    for node in my_etree.iter(tag=etree.Element):
        if self._check_element_is(node, 't'):
            yield(node, node.text)

def _check_element_is(self, element, typr_char):
    word_schema = "http://schemas.openxmlformats.org/wordprocessingml/2006/main"
    return element.tag == '{%s}%s' %(word_schema, type_char)

xml_from_file = self.get_word_xml(wod_filename)
xml_tree = self.get_xml_tree(xml_from_file)
for node, txt in self._itertext(xml_tree):
    print txt
