Python:如何修改Microsoft Office文件的元数据? [英] Python: How to Modify metadata of Microsoft Office files?

问题描述

如何修改Microsoft Office文档的元数据?我找到了Jpg，PNG和PDF文件的结果数量.有人可以建议Office文件元数据的图书馆吗?

解决方案

对于较新的格式，它们通常只是压缩的xml，因此您可以使用标准库来解压缩和解析xml.以前发布了一些用于捕获文档创建者的代码，作为对stackoverflow的回答.

import zipfile, lxml.etree

# open zipfile
zf = zipfile.ZipFile('my_doc.docx')
# use lxml to parse the xml file we are interested in
doc = lxml.etree.fromstring(zf.read('docProps/core.xml'))
# retrieve creator
ns={'dc': 'http://purl.org/dc/elements/1.1/'}
creator = doc.xpath('//dc:creator', namespaces=ns)[0].text

对于较旧的格式，您可能需要查看 hach​​oir-元数据库

解决方案

For newer formats they are often just zipped xml, so you can use standard libs to unzip and parse the xml. Some code to grab the document creator was previously posted as an answer on stackoverflow.

import zipfile, lxml.etree

# open zipfile
zf = zipfile.ZipFile('my_doc.docx')
# use lxml to parse the xml file we are interested in
doc = lxml.etree.fromstring(zf.read('docProps/core.xml'))
# retrieve creator
ns={'dc': 'http://purl.org/dc/elements/1.1/'}
creator = doc.xpath('//dc:creator', namespaces=ns)[0].text

For older formats you might want to look at the hachoir-metadata library
