I've started using elementtree and don't understand how to use it to manipulate and replace nodes. I know how to do this using a simple, but inefficient parser I wrote, but I'd rather learn to use a better tool - especially as it is to be added to the standard library.
I'll use a simple, but representative example. Suppose I have the following text, where I inserted blank lines to isolate the part I want to manipulate. =================== <html> <body> <p> This is some text. </p> <pre class="text"> a = 6*7 print a </pre> <p> Done. </p> </body> </html> ==================== Now, I would like to find all <pre> tags of the "text" class and 1. change the class value 2. append another node ( <textarea> ) 3. surround the both nodes by a third one ( <form> ) ================== <html> <body> <p> This is some text. <p> <form> <pre class="text2"> a = 6*7 print a </pre> <textarea cols=80 name="code"> </textarea> <input type="submit"></input> </form> <p> Done. </p> </body> </html> =============== Any help would be appreciated.
