Changing data of xhtml document
Hello list! I've got a unicode string which holds an xhtml website, begining with !DOCTYPE ... and a functions which alters strings in a certain way. I want to replace all actual data in this xhtml unicode string with the function's output. (By 'actual data' I mean anything that I thought I should use the XMLGenerator package, but first, I don't like it's output, and second, it complaints about the !DOCTYPE ... tag. Also, it writes the ?xml ? tag which I want to avoid at this stage. Are there any really easy solutions to this problem? Any modules that could be helpful for slight modification of such sgmlish files? The downside of SGMLParser is that I have to override all parser functions to actually leave everything intact instead of doing nothing and override characters(data) to print the altered data.

Re: psp php integration

However, I do not want to recode the navigation part of the site which is currently coded using PHP. Somehow I need to merge the outputs of the PHP file and my PSP file to create the HTML output which is sent to the browser. Can this be done inside my PSP file? If not, is there any other way in Python (or PHP) to achieve this? I have never used PSP, (I prefer old-time cgi's) but one *BAD* solution is that you can open a local connection to your server asking for the .php file through the psp file which should do the extra functionality, or vice versa.

Are you telling me that the ONLY thing you use dictobj objects for is to print them? I'm sorry to disappoint you, but yes. When you have a long text template to fill-out, with lots of %(foo)s, and all those foos are attributes of an object, it really helps to have dictobj. I don't think so. I do know how to print an object, amazingly. Please, tell me, how would you print it in my case? Perhaps you would like to explain how you use the rest of the functionality of the dictobj, instead of taking my words out of context and giving an inane answer. I dont see _ANY_ other functionality in the dictobj class. Do you? Why jump through all those hoops to get attributes when Python already provides indexing and attribute grabbing machinery that work well? Why do you bother to subclass dict, only to mangle the dict __getitem__ method so that you can no longer retrieve items from the dict? Because *obviously* I don't know of these indexing and attribute grabbing machineries you are talking about in my case. If you cared to read my first post, all I asked was for the normal, built-in way to do it. Now, is there one, or not? -- Thanos Tsouanas .: My Music: http://www.thanostsouanas.com/ http://thanos.sians.org/ .: Sians Music: http://www.sians.org/ -- http://mail.python.org/mailman/listinfo/python-list

I didn't know about it, but I knew about object.__dict__ which is, as I see equivalent with vars(object). But it doesn't do the job for me, since it fails to grab all obj.foo's, some of them being properties, etc. vars() is good to know though, Thanks! -- Thanos Tsouanas .: My Music: http://www.thanostsouanas.com/ http://thanos.sians.org/ .: Sians Music: http://www.sians.org/ -- http://mail.python.org/mailman/listinfo/python-list

Is there one? Now if your *only* need is to access object as a dict for formated output, you don't need to subclass dict. This is (well, should be) enough: class Wrapper(object): def __init__(self, obj): self._obj = obj def __getitem__(self, name): return getattr(self._obj, name) This works with 'normal' attributes as well as with properties. Notice that this wrapper is read-only, and don't pretend to be a real dictionnary - but still it implements the minimum required interface for %(attname)s like formatting. Thanks!! You made clear what 'the extra functionality' was. Indeed there is no need to subclass dict... HTH it does!
