使用python textract或替代lib从.doc文件中提取页眉和页脚内容

Question

I'm trying to extract page content along with header and footer content. I tried using textract lib. for .docx it's good. But it's not the same for .doc

I tried checking other libraries but none of it worked for me.

Below I have snippet for .docx

import textract
def convert_to_txt(filename):
    try:
        my_text = textract.process(filename, encoding='ascii')
    except Exception as e:
        msg = "Couldn't able to open the file: {}".format(filename)
        raise RuntimeError(msg)
    return my_text

There is a better solution to this problem :

Method Used to extract

using MS XML Word document

just zip the word document using zip module, It will give you access to xml format of word document, then you can use simple xml node extraction for text.

Following is the working code that extracts Header , Footer , Text Data from a docx file.

try:
    from xml.etree.cElementTree import XML
except ImportError:
    from xml.etree.ElementTree import XML
import zipfile    
WORD_NAMESPACE = '{http://schemas.openxmlformats.org/wordprocessingml/2006/main}'
PARA = WORD_NAMESPACE + 'p'
TEXT = WORD_NAMESPACE + 't'


def get_docx_text(path):
    """
    Take the path of a docx file as argument, return the text in unicode.
    """
    document = zipfile.ZipFile(path)
    contentToRead = ["header2.xml", "document.xml", "footer2.xml"]
    paragraphs = []

    for xmlfile in contentToRead:
        xml_content = document.read('word/{}'.format(xmlfile))
        tree = XML(xml_content)
        for paragraph in tree.getiterator(PARA):
            texts = [node.text
                     for node in paragraph.getiterator(TEXT)
                     if node.text]
            if texts:
                textData = ''.join(texts)
                if xmlfile == "footer2.xml":
                    extractedTxt = "Footer : " + textData
                elif xmlfile == "header2.xml":
                    extractedTxt = "Header : " + textData
                else:
                    extractedTxt = textData

                paragraphs.append(extractedTxt)
    document.close()
    return '\n\n'.join(paragraphs)


print(get_docx_text("E:\\path_to.docx"))
