There is a * in the path of the following URL. Does it have special purpose?
...
Thanks
The most probable explanation is that some kind of parsing is taking place using javascript. Where did you find that?
If i'm correct it is called URLmapping, it uses some kind of framework to fill in the asterisk with dynamics

I can't find a good source of information about this. Why would I want to use <b:skin>, <b:section>, <b:widget> if there is a possibility to create a page without that? And what advantage is there of using those?
Also I have to necessarily include one <b:section>, but it's possible to leave it empty. Why is this including mandatory then?
I guess the answer is yes, but what’s the easiest way to do it? I use Template::Toolkit::Simple, if that makes a difference.
I don't think so, but since it's based on a template - just make your template pretty printed.
If you want to create pretty-print HTML then you have to use Template::Plugin::HTML instead of Template::Toolkit::Simple.
You may also try these approaches: Template::Flute and Markapl
I would like to parse a html page and extract the meaningful text from it. Anyone knows some good algorithms to do this?
I develop my applications on Rails, but I think ruby is a bit slow in this, so I think if exists some good library in c for this it would be appropriate.
Thanks!!
PD: Please do not recommend anything with java
UPDATE:
I found this link text
Sadly, is in python
Use Nokogiri, which is fast and written in C, for Ruby.
(Using regexp to parse recursive expressions like HTML is notoriously difficult and error prone and I would not go down that path. I only mention this in the answer as this issue seems to crop up again and again.)
With a real parser like for instance Nokogiri mentioned above, you also get the added benefit that the structure and logic of the HTML document is preserved, and sometimes you really need those clues.
Solutions integrating with Ruby
use Nokogiri as recommended by Amigable Clark kant
Use Hpricot

If your HTML is well-formed, you could use the Expat XML Parser for this.
For something more targeted toward HTML-only, the W3C actually released the code for the LibWWW, which contains a simple HTML parser (documentation).
Lynx is able to do this. This is open source if you want to take a look at it.
You should strip all angle-bracketed part from text and then collapse white-spaces.
In theory the < and > should not be there in other cases. Pages contain < and > everywhere instead of them.
Collapsing whitespaces: Convert all TAB, newline, etc to spaces, then replace every sequence of spaces to a single space.
UPDATE: And you should start after finding the <body> tag.
I'm using the DataContractSerializer to convert and object returned from a WCF call to xml. The client would like to see that xml string in a webpage. If I output the string directly to a label, the browser strips out the angle brackets obviously. My question is how can I do something similar to StackOverflow? Are they doing a find & replace to replace angle brackets with their html entities? I see they are doing a code tag inside a pre tag and then making spans with the appropriate class. Is there an existing utility out there I can use to do this instead of writing some kind of parsing routine. I'm sure something free must be out there. If anyone can direct to the right place or some code that can easily accomplish this, I would greatly appreciate it. I apologize if this is more of a meta.stackoverflow question. Thanks for any tips.
The basic answer is that to get HTML displayed as typed, special characters and all, you need to replace the special characters (<, > etc.), with their escaped equivalents (>, < etc.). Beyond that if you want syntax colouring you'll have to parse the input to identify the keywords etc.
A full list of the special characters and their escape codes can be found here, but this is just one site of many.
you're talking about "pretty print".. if you want to diplay source code you could use this link 16 Free Javascript Code Syntax Highlighters For Better Programming
But if you want to display only xml.. there are some functions on the web that could help you with that, like this one: XML PHP Pretty Printer
and dont forget the special characters =)
good luck
Could anyone give me a good use case for ActionScript dynamic classes?
Because it really looks like a bad pratice, for me, in every case.
Anything that uses Proxy must by extension be dynamic. I use Proxy fairly regularly; for example, here's a replacement syntax for ExternalInterface using Proxy.
URLVariables, for example.
You could store the data in a dictionary / object / array too, but you don't gain much in this case, I think, and you cut down some boilerplate.
Well you could use an Object object, but using a dynamic class ensures that it is typed. That's the way I see it, and it's the only reason I would use them. What Juan Pablo is saying is a good reason too.
