python生成RSS（PyRSS2Gen）

既然能够用python解析rss，那么也顺带研究下生成rss。

其实很简单，只是生成一个比较特殊点的xml文档而已。

这里我使用了PyRss2Gen,用法很简单，看代码就知道了，如下：

 1 import datetime

 2 import PyRSS2Gen

 3

 4 rss = PyRSS2Gen.RSS2(

 5    title = "Andrew‘s PyRSS2Gen feed",

 6    link = "http://www.dalkescientific.com/Python/PyRSS2Gen.html",

 7    description = "The latest news about PyRSS2Gen, a "

 8                  "Python library for generating RSS2 feeds",

 9

10    lastBuildDate = datetime.datetime.now(),

11

12    items = [

13       PyRSS2Gen.RSSItem(

14         title = "PyRSS2Gen-0.0 released",

15         link = "http://www.dalkescientific.com/news/030906-PyRSS2Gen.html",

16         description = "Dalke Scientific today announced PyRSS2Gen-0.0, "

17                       "a library for generating RSS feeds for Python.  ",

18         guid = PyRSS2Gen.Guid("http://www.dalkescientific.com/news/"

19                          "030906-PyRSS2Gen.html"),

20         pubDate = datetime.datetime(2003, 9, 6, 21, 31)),

21       PyRSS2Gen.RSSItem(

22         title = "Thoughts on RSS feeds for bioinformatics",

23         link = "http://www.dalkescientific.com/writings/diary/"

24                "archive/2003/09/06/RSS.html",

25         description = "One of the reasons I wrote PyRSS2Gen was to "

26                       "experiment with RSS for data collection in "

27                       "bioinformatics.  Last year I came across...",

28         guid = PyRSS2Gen.Guid("http://www.dalkescientific.com/writings/"

29                               "diary/archive/2003/09/06/RSS.html"),

30         pubDate = datetime.datetime(2003, 9, 6, 21, 49)),

31    ])

32

33 rss.write_xml(open("pyrss2gen.xml", "w"))

这个生成的rss文档是这样的：

 1 <?xml version="1.0" encoding="iso-8859-1"?>

 2 <rss version="2.0">

 3 <channel>

 4 <title>Andrew‘s PyRSS2Gen feed</title>
