使用python查找图像当前docx文件

Question

我如何找到文档文件中存在的图像图像，python中是否有用于此的任何模块。我搜索了但没有用。这就是我们可以从Word文件读取的方式。下面的代码不提供有关文件中存在的图像的信息

 from  docx import Document

 documnet=Document('new-file-name.docx')
 para=documnet.paragraphs
     for par in para:
         print par.text

Answer 1

由于.docx文件是zip文件，因此可以使用zipfile模块：

import zipfile

z = zipfile.ZipFile("1.docx")

#print list of valid attributes for ZipFile object
print dir(z)

#print all files in zip archive
all_files = z.namelist()
print all_files

#get all files in word/media/ directory
images = filter(lambda x: x.startswith('word/media/'), all_files)
print images

#open an image and save it
image1 = z.open('word/media/image1.jpeg').read()
f = open('image1.jpeg','wb')
f.write(image1)

#Extract file
z.extract('word/media/image1.jpeg', r'path_to_dir')

Answer 2

您必须首先将所有图像文件解压缩为 .zip，在 XML 代码中查找图像元素并将每个图像与其 rId 相关联。

import os
import docx
import docx2txt

# Extract the images to img_folder/
docx2txt.process('document.docx', 'img_folder/')

# Open you .docx document
doc = docx.Document('document.docx')

# Save all 'rId:filenames' relationships in an dictionary named rels
rels = {}
for r in doc.part.rels.values():
    if isinstance(r._target, docx.parts.image.ImagePart):
        rels[r.rId] = os.path.basename(r._target.partname)

# Then process your text
for paragraph in doc.paragraphs:
    # If you find an image
    if 'Graphic' in paragraph._p.xml:
        # Get the rId of the image
        for rId in rels:
            if rId in paragraph._p.xml:
                # Your image will be in os.path.join(img_path, rels[rId])
    else:
        # It's not an image
