我将如何使用 Python 解析'Front Matter'



我似乎找不到任何关于如何用Python解析"Front Matter"的例子。我有以下内容:

---
name: David
password: dwewwsadas
email: david@domain.com
websiteName: Website Name
websitePrefix: websiteprefix
websiteDomain: domain.com
action: create
---

我正在使用以下代码:

listing = os.listdir(path)
for infile in listing:
    stream = open(os.path.join(path, infile), 'r')
    docs = yaml.load_all(stream)
    for doc in docs:
        for k,v in doc.items():
            print k, "->", v
    print "n",

由于第二组---

,我一直收到错误

我知道这是一个老问题,但我只是遇到了同样的问题,并使用了python-frontmatter。下面是一个向Front matter添加新变量的示例:

import frontmatter
import io
from os.path import basename, splitext
import glob
# Where are the files to modify
path = "en/*.markdown"
# Loop through all files
for fname in glob.glob(path):
    with io.open(fname, 'r') as f:
        # Parse file's front matter
        post = frontmatter.load(f)
        if post.get('author') == None:
            post['author'] = "alex"
            # Save the modified file
            newfile = io.open(fname, 'w', encoding='utf8')
            frontmatter.dump(post, newfile)
            newfile.close()

:如何使用python 解析frontmatter

---启动新文档,这会导致第二个文档为空,第二部分的docNone。您遍历doc的键和值对,就好像每个doc都是Python dict或等效类型,但None不是,所以您应该在循环中测试这一点(当然有多种方法可以做到这一点,以及如果doc不是dict该怎么办):

....
for doc in yaml.load_all(stream):
    if hasattr(doc, 'items'):
        for k, v in doc.items():
            print k, "->", v
    else:
        print doc
