python开发_html_html处理
''' python中，html模块提供了只提供了一个方法： html.escape(s, quote = True) 该方法主要是把html文件中的特殊字符(&,<,>,",'等)转换为HTML-safe字符 '''
下面是我做的一个demo：
运行效果：
Python 3.3.2 (v3.3.2:d047928ae3f6, May 16 2013, 00:03:43) [MSC v.1600 32 bit (Intel)] on win32 Type "copyright", "credits" or "license()" for more information. >>> ================================ RESTART ================================ >>> 源html文件: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title> Python Html module </title> <meta name="Generator" content="EditPlus"> <meta name="Author" content="Hongten"> <meta name="Keywords" content="hongten,python"> <meta name="Description" content="this blogs is about python"> </head> <body> <table border = "1"> <tr> <td> Author </td> <td> Hongten </td> <td> Mail </td> <td> hongtenzone@foxmail.com </td> </tr> <tr> <td> Blos </td> <td> <a href="http://www.blogs.com/hongten">http://www.blogs.com/hongten</a> </td> <td> QQ </td> <td> 648719819 </td> </tr> </table> </body> </html> ################################################## 转换html文件: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title> Python Html module </title> <meta name="Generator" content="EditPlus"> <meta name="Author" content="Hongten"> <meta name="Keywords" content="hongten,python"> <meta name="Description" content="this blogs is about python"> </head> <body> <table border = "1"> <tr> <td> Author </td> <td> Hongten </td> <td> Mail </td> <td> hongtenzone@foxmail.com </td> </tr> <tr> <td> Blos </td> <td> <a href="http://www.blogs.com/hongten">http://www.blogs.com/hongten</a> </td> <td> QQ </td> <td> 648719819 </td> </tr> </table> </body> </html> >>>
经过源文件内容和转换后的内容相比较，我想你知道html.escape()方法的作用了吧
