html-manipulation

I need a servlet filter that will capture all input, then mangle that input, inserting a special token in every form. Imagine that the filter is tied to all requests (E.g. url-pattern=* ). I have the code for capture of content, but it doesn't seem like the RequestWrapper is robust enough to capture all input. Some input returns zero bytes and then I can't "stream" that content back to the user. For example, we are still using Struts 1.3.10 and any Struts code does not "capture" properly, we get zero byte content. I believe it is because of how Struts handles forwards. If there is a forward

Here is what I need to be able to do: I need to match the following tag: <SPAN style="TEXT-DECORATION: underline">text sample</SPAN> I need to replace the span with an html3 compliant tag, but keep the text in between. The final tag should look like this after replacement: <u>text sample</u> I'm just not good with regular expressions and can't seem to come up with the answer. Thank you in advance. Regular expressions are not designed for tag manipulation. If you have any form of nesting going on, it gets messy. However, given the very simple example provided you could perhaps do this:

I'm having an html file, index.php I want to take the content within a <div> with the class main of that file and replace it with another text. How can i achieve that? Sample content in html: <div class="main"> Replace this text with some code! </div> I want get the content within this div using php and replace it with another content. But I have no idea on how to do this. Update: I'm aware of client side trick with javascript. I want to do this server side. And the file will be html and not php. so I think i have to open the html in php and do this, though i don't precisely how. Can this be

I have a DIV with a form in it. When users submit the form and it gets successfully submitted, I replace the form with a simple "everything is good now" message: $("#some_div").html("Yeah all good mate!"); Is there a good way to "reset" the div to its "original state" as per the HTML it has arrived with? I can only think of actually doing something like this: //before I change the DIV var originalState = $("#some_div").html(); //manipulate the DIV //... //push the state back $("#some_div").html(originalState); It doesn't look very elegant - I guess there is a better solution for this, no?

I'm trying to do my frist steps with jQuery but I have some trouble to understand how to find a list of child elements from a div parent element. I'm used to work with ActionScript 2 and ActionScript 3 so i could mistake some concept, like what is the better way to randomize a sequence of div elements with jQuery! I have this simple portion of HTML code: <div class="band"> <div class="member"> <ul> <li>John</li> <li>Lennon</li> </ul> </div> <div class="member"> <ul> <li>Paul</li> <li>McCartney</li> </ul> </div> <div class="member"> <ul> <li>George</li> <li>Harrison</li> </ul> </div> <div class
