Docutils：遍历部分？

Question

如何在Sphinx中遍历文档的每个部分名称？

（doctils的文档在哪里？在Sphinx Application API之外找到有用的东西是非常困难的;即使查看source code for docutils/nodes.py也没有多大帮助。）

Answer 1

最后通过反复试验找出答案：/

import docutils

def doctree_resolved(app, doctree, docname):
    for section in doctree.traverse(docutils.nodes.section):
        title = section.next_node(docutils.nodes.Titular)
        if title:
            print title.astext()

def setup(app):
    app.connect('doctree-resolved', doctree_resolved)
