python-3.x - 如何从段落python docx获取图像(inlineshape)

Question

我想逐段阅读docx文档，如果有图片(InlineShape)，然后用它周围的文字处理它。函数 Document.inline_shapes 将给出文档中所有内联形状的列表。但我想得到一个，如果存在的话，它正好出现在当前段落中......

代码示例:

from docx import Document

doc = Document("test.docx")
blip = doc.inline_shapes[0]._inline.graphic.graphicData.pic.blipFill.blip
rID = blip.embed
document_part = doc.part
image_part = document_part.related_parts[rID]

fr = open("test.png", "wb")
fr.write(image_part._blob)
fr.close()

(这就是我想保存这些图片的方式)

假设您的段落是标准的，您可以使用以下代码来查找图像

import xml.etree.ElementTree as ET
def hasImage(par):
    """get all of the images in a paragraph 
    :param par: a paragraph object from docx
    :return: a list of r:embed 
    """
    ids = []
    root = ET.fromstring(par._p.xml)
    namespace = {
             'a':"http://schemas.openxmlformats.org/drawingml/2006/main", \
             'r':"http://schemas.openxmlformats.org/officeDocument/2006/relationships", \
             'wp':"http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing"}

    inlines = root.findall('.//wp:inline',namespace)
    for inline in inlines:
        imgs = inline.findall('.//a:blip', namespace)
        for img in imgs:     
            id = img.attrib['{{{0}}}embed'.format(namespace['r'])]
        ids.append(id)

    return ids
