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>
