python 中的 feedparser 输出意外截断
Output of feedparser in python unexpectedly truncated
我正在编写一段代码来解析来自 RSS 提要的信息。我正在存储解析后的信息以供以后研究。在手头的案例中，我想存储 [姓名、姓氏、内幕交易类型、价格……] 等信息。
我的问题
我尝试解析的字符串有超过 1800 个字符，但我的解析器输出的字符串只有大约 330 个字符，并以“...”结尾。
我的问题是 如何调整 Python 中 feedparser 解析的字符串的最大长度？ 或 为什么我的代码被截断并且没有完整列出打印还是存储？
我试过的
import feedparser
InsiderFeed = feedparser.parse("https://www.finanztreff.de/rdf_news_category-insidertrades.rss")
summary = InsiderFeed.entries[0].summary # just to give one example here instead of looping through full list
print(summary)
输出
看起来像：

但应该看起来像：（忽略刹车 \n 似乎默认情况下由 feedparser 清理）

在此处使用此示例 http://www.finanztreff.de/news/dgap-dd-encavis-ag-english/20845911。
我也试图在 feedparser documentation 中找到一个合适的标志/关键字来定义我解析的字符串的最大长度，但没有成功。
期待您的帮助，不胜感激！

事实证明 feedparser 没有问题。网站 RSS 提要的内容只是网站上显示内容的截断版本，因为下面提要的摘录清楚地显示了每个标题。
看来我必须解析 RSS 提要附带的链接以获得完整的内容，并解析它以获得我需要的信息。
